A revision of infrageneric classification in Astelia Banks & Sol. ex R.Br. (Asteliaceae) (original) (raw)

Abstract Abstract

Systematic investigations and phylogenetic analyses have indicated that _Astelia, as currently circumscribed, is paraphyletic, with _Collospermum nested within it. Further, _Astelia subgenus Astelia is polyphyletic, and _Astelia subgenera _Asteliopsis and _Tricella are paraphyletic, as currently circumscribed. Revision of the subgeneric classification of _Astelia is warranted to ensure classification accurately reflects the evolutionary history of these taxa. _Collospermum is relegated to synonymy within _Astelia. _Astelia is dioecious or polygamodioecious, with a superior ovary, anthers dorsi- or basifixed, pistillodes or pistils that have a single short or poorly defined style, a 3 lobed stigma, and fleshy uni- or trilocular fruit with funicular hairs that are poorly to well developed. _Astelia subgenus Collospermum (Skottsb.) Birch is described. A key to _Astelia sections is provided. _Astelia hastata Colenso, _Astelia montana Seem., and _Astelia microsperma Colenso pro parte are resurrected and the new combination _Astelia samoense (Skottsb.) Birch, comb. nov. is made.

Introduction

_Astelia Banks & Sol. ex R.Br. is the largest genus in _Asteliaceae Dumort., containing twenty-six species and three non-nominotypical varieties with an Austral-Pacific distribution. _Astelia species exhibit a range of growth forms including low, cushion-forming and tall, clustered habits. _Astelia species grow in a diverse range of habitats including coastal, lowland wetlands, tropical and temperate lowland forests, tropical montane cloud forests, sub-alpine heath, alpine fellfields and grasslands, and bog habitats. Many _Astelia species are facultatively epiphytic and three species are primarily epiphytic. _Collospermum Skottsb. includes four species that occur in lowland forests and in lowland and tropical montane cloud forests in New Zealand, the Independent State of Samoa and the Republics of Fiji and Vanuatu. All species exhibit a tall, clustered habit and are primarily epiphytic, although plants that fall to the ground can persist for long periods.

_Astelia and _Collospermum share many morphological characters (Bayer et al. 1998, Rudall et al. 1998). All _Asteliaceae genera have branched hairs that are otherwise uncommon in the _Lilianae (Bayer et al. 1998) and those of _Astelia and _Collospermum are dense, at least in the young leaves of most species. The tomentum of _Astelia and _Collospermum consist of a multi-celled stalk, frayed unicellular filaments that form a basal wool adjacent to the stalk, and linear or ovate scales that are a single cell thick (McCarthy 1928, Skottsberg 1934, L. B. Moore 1980, Rudall et al. 1998). In _Astelia the scales are linear, may be short or long, and the stalk is attached at the base of the scale. In _Collospermum, the scales are ovate, short, and the stalk is peltate. Scales may be present on the adaxial and/or abaxial leaf surfaces, inflorescences, and flowers. On the leaves of _Astelia species the scales may become fused to form a membranous pellicle over the leaf epidermis. _Astelia and Collospermum have superior ovaries that are uni- or trilocular and trilocular, respectively. Published chromosome numbers for Astelia taxa range from 2_n = 60 to 2_n = 210 (Wheeler 1966, Dawson and Beuzenberg 2000, de Lange et al. 2004). Darlington and Wylie (1955) proposed a basic chromosome number for _Astelia of x = 8, but Wheeler (1966) considered the basic chromosome number to be x = 5, 7, or 35. _Collospermum hastatum and _Collospermum microspermum are the only _Collospermum taxa for which chromosome numbers are known and both have a chromosome number of n = 35.

Skottsberg (1934) segregated _Collospermum from _Astelia based on the presence of simple lateral racemes, dimorphism of staminate and pistillate plants, basifixed anthers, long style papillae, and mucilaginous seed hairs of the former, which differ from the predominantly paniculate lateral racemes, versatile anthers, and poorly developed mucilaginous seed hairs of the latter (Birch unpublished PhD thesis 2011, Birch et al. 2012). However, morphological (Bayer et al. 1998, Birch unpublished PhD thesis 2011), cytological (Wheeler 1966, Moore 1980), and molecular (Birch unpublished PhD thesis 2011, Birch et al. 2012) data suggested a close evolutionary relationship between these genera. Moore (1980) considered that a re-evaluation of the circumscriptions of _Astelia and _Collospermum was warranted due to the production of viable progeny from intergeneric crosses. _Collospermum, while monophyletic, was nested within _Astelia in phylogenetic reconstructions based on combined chloroplast and nuclear sequence data applying Bayesian inference, maximum likelihood, and maximum parsimony criteria (Birch unpublished PhD thesis 2011, Birch et al. 2012). As a result, those authors recognized a broadly circumscribed _Astelia s.l., including _Collospermum.

Within _Astelia, Skottsberg (1934) recognized three subgenera (_Astelia subg. Astelia Skottsb., _Astelia subg. Asteliopsis Skottsb., and _Astelia subg. Tricella Skottsb.) based on open or cushion-forming growth form, degree of tepal fusion, ovary division, and seed shape. Within these subgenera, he recognized seven sections (_Astelia sect. Astelia Skottsb., _Astelia sect. Desmoneuron Skottsb., _Astelia sect. Isoneuron Skottsb., _Astelia sect. Micrastelia Skottsb., _Astelia sect. Palaeastelia Skottsb., _Astelia sect. Periastelia Skottsb., and _Astelia sect. Tricella Skottsb.) based on leaf venation, pistillode size, seed surface features, and extent of funicle development. In phylogenetic analyses (Birch unpublished PhD thesis 2011, Birch et al. 2012), each of Skottsberg’s (1934) sections, except _Astelia sect. Tricella, were monophyletic, _Astelia subg. Astelia and _Astelia subg. Asteliopsis were polyphyletic, and _Astelia subg. Tricella was paraphyletic. A revised circumscription of _Astelia subgenera is proposed that accurately reflects the evolutionary relationships within the genus. _Collospermum is relegated to synonomy under _Astelia. Skottsberg’s sections are retained as they are monophyletic and accurately capture the extensive morphological diversity that is present within the subgenera.

A revision based on recognition of monophyletic taxa is proposed here. Multiple characters support the proposed circumscription of _Astelia. All taxa are dioecious or polygamodioecious, with a superior ovary, dorsi- or basifixed anthers, pistillodes or pistils that have a single short or poorly defined style, a 3 lobed stigma, and fleshy uni- or trilocular fruit with funicular hairs that are poorly to well developed.

Methods

Taxonomic sampling

All _Astelia taxa, (twenty-six species and three non-nominotypical varieties) and all _Collospermum (four species) were included in this study. Herbarium specimens were examined from the following herbaria: (AK), (BISH), (CHR), (GH), (K), (MEL), (MO), (P), (PTBG), (US), and (WELT). Type specimens were examined from AK, BISH, MEL, P, WELT and digital images of type specimens were examined from CHR and K (Herbarium abbreviations follow Index Herbariorum (Thiers continuously updated).

Morphological data and analyses

Morphological data were obtained for 410 herbarium specimens (Appendix 1). Data were obtained for ten specimens per species, including five staminate and five pistillate specimens for species with unisexual flowers. Measurements and scores were averaged across all specimens to give a mean value for each taxon. Flower and fruit color data were obtained from multiple sources including field observations, specimen label data, and taxon descriptions in national floras (Drake del Castillo 1893, L. B. Moore and Edgar 1976, Coode 1978, D. M. Moore 1983, Williams 1987, Wagner et al. 1999).

Morphological characters that varied at or below the genus rank were measured or scored for all _Astelia and _Collospermum taxa in the field and/or herbarium. Herbarium specimens were studied under a dissecting microscope and measurements obtained using digital calipers. Pollen and seed characters were examined directly from material obtained from herbarium specimens after coating with gold-palladium using a Hitachi S-4800 field emission (SEM) at the Biological Electron Microscope Facility, Pacific Biosciences Research Center of the University of Hawai‘i at Mānoa. Images were digitally processed and the final plates were prepared in Photoshop 10.0.

_Astelia microsperma

Colenso pro parte

Remarks.

_Astelia microsperma was described by Colenso based on a specimen at Kew that contained material from two species (Skottsberg 1934). The species description “referred to both, but mainly to the pistillate raceme in the envelope” (Skottsberg 1934, 82). Skottsberg (1934) lectotypified the fruiting material in the packet (K000524879) as the type material of _Astelia microsperma (as syn. _Collospermum microspermum) and determined the remaining material on the specimen (K000524882) as _Astelia hastata (as syn. _Collospermum hastatum).

Excluded species.

_Astelia montana

Seem.

Remarks.

Seemann stated in the preface of Flora Vitiensis (1965, iv) that “the first set of specimens collected by me were deposited at the Royal Herbarium, Kew and from these the plates accompanying this work have chiefly been taken”. The type material of _Astelia montana, which was effectively published in Flora Vitiensis, can reasonably be expected to have been accessioned at Kew. Two sheets containing _Astelia montana specimens collected by Seemann are accessioned at K. One sheet (K000524875) includes a vegetative plant collected at Mt. Mbuke Levu and a second sheet (K000524876) includes a leaf fragment annotated as collected at “Vuna, June 1860” and a pistillate inflorescence labeled as collected by Seemann (n. 641) in 1860. Sheet K000524876 includes the illustrations of the pistillate flower, staminode, berry and seed that appear in the plate that accompanies the protologue of _Astelia montana (Seemann 1965).

The pistillate inflorescence labeled as Seemann’s collection n. 641 on sheet K000524876 represents the holotype. According to Seemann’s (1962, 1965) accounts of his field collections, he successfully ascended Mt. Mbuke Levu only once, on 6 September 1860. The vegetative specimen on sheet K000524875 was also collected by Seemann on “Buke Levu” [_sic_]. A type specimen can be mounted on multiple sheets “as long as the parts are clearly labeled as being part of that same specimen” (International Botanical Congress and JH Wiersema 2015); Article 8.3). Although it is likely that sheets K000524875 and K00524876 represent a single specimen that was mounted on separate sheets (Birch pers. comm., Smith 1979), they were not clearly labeled as such. Therefore, K000524875 is considered a duplicate. The leaf fragment on sheet K000524876 annotated as collected in “Vuna June 1860” may represent a fragment of an earlier collection from Vuna on the island of Taveuni (Smith 1979) where Seemann spent time during June 1860 (Seemann 1962).

_Astelia samoense

(Skottsb.) Birch comb. nov.

urn:lsid:ipni.org:names:77148140-1

Remarks.

Two specimens were identified by Skottsberg (1934) as types in the list of specimens examined. This included a staminate specimen (Vaupel 356 noted by Skottsberg (1934) as accessioned at HBG) and a pistillate specimen (K. and L. Rechinger n. 4334 noted by Skottsberg (1934) as accessioned at W). The pistillate specimen of Rechinger is not extant at W (pers. comm. A. Löckher, Department of Botany at Naturhistorisches Museum Wien). Efforts are underway to locate type material of _Astelia samoense held in herbaria globally.

Diacritical signs, which should be suppressed in species names (International Botanical Congress and JH Wiersema 2015; Article 60.6) have not been transferred from _Collospermum samoënse.

_Astelia subg. Tricella

Skottsb.

Note.

Flowers with a short (_Astelia sect. Periastelia) or long (_Astelia sect. Tricella) perianth tube (0.3–3.5 mm); anthers dorsifixed, versatile; seeds ellipsoid, fusiform, or ovoid; funicle short, truncate, mucilaginous funicular hairs poorly developed; Type: _Astelia nervosa Banks & Sol. ex Hook.f., designated here.

Remarks.

_Astelia subg. Tricella is revised to include both _Astelia sect. Tricella and _Astelia sect. Periastelia, which form a well supported clade in phylogenetic analyses (Birch unpublished PhD thesis 2011, Birch et al. 2012). _Astelia sect. Periastelia is monophyletic; however _Astelia sect. Tricella is present as a grade and relationships within each of these sections remain equivocal.

_Astelia sect. Tricella

Skottsb.

Note.

Compact to open growth form; leaves linear or ensiform; inflorescences bearing many flowers; staminate flowers with short or long filaments (0.8–3.5 mm); pistillate flowers with long outer tepals (2.3–5.3 × 1.2–2.6 mm); ovary trilocular, long (2.9–6.8 mm); fruit globose with few seeds per fruit (4–12); seeds long and wide (2.2–3.7 × 1.3–2.3 mm).

_Astelia sect. Periastelia

Skottsb.

Note.

Open growth form; leaves linear or ensiform; inflorescences bearing many flowers; staminate flowers with short or long filaments (0.9–2.8 mm); pistillate flowers with long outer tepals (2.3–5.3 × 1.2–2.6 mm); ovary trilocular, intermediate length (1.8–4.6 mm); fruit globose, few seeds per fruit (4–12); seeds long and narrow (1.8–3.6 × 0.7–1.6 mm).

Incertae sedis

_Astelia sect. Micrastelia

Skottsb.

Note.

Low, compact, turf forming growth form; leaves caniculate; inflorescence bearing few flowers; staminate flowers with short filaments (0.6–1.9 mm); pistillate flowers with short outer tepals (2.6–3.8 × 0.8–1.3 mm); ovary trilocular, intermediate length (2.6–3.8 mm); fruit ellipsoid, many seeds per fruit (17–24); seeds short and narrow (1.1–1.7 × 0.5–0.8 mm). Type: _Astelia pumila (Forst.) Gaudich.

Remarks.

The relationships of _Astelia sect. Micrastelia are poorly resolved, with alternate relationships with _Astelia subg. Asteliopsis and the clade containing _Astelia subg. Tricella and _Collospermum (Birch unpublished PhD thesis 2011, Birch et al. 2012). _Astelia sect. Microastelia contains a single species, _Astelia pumila, which is a compact, turf-forming plant and dominant component of _Astelia moorland in Chile, the Falkland Islands, and Tierra del Fuego. As a cushion-forming species, it differs morphologically from _Astelia subg. Asteliopsis, which contains species with open, spreading growth form that are epiphytic or terrestrial and primarily found of the understory in lowland to montane forests. _Astelia pumila does share morphological features with _Astelia subg. Asteliopsis (e.g. short pistillode or pistil) and, alternatively, with _Astelia subg. Collospermum and _Astelia subg. Tricella (e.g. seeds with a short, truncate funicle). The subgeneric placement of _Astelia sect. Micrastelia remains equivocal and the section is unplaced (incertae sedis).

Included species and distribution.

Chile, Falkland Islands, Tierra del Fuego: _Astelia pumila (Forst.) Gaudich.

Habitat.

Lowland (low latitudes) to sub-alpine (mid and higher latitudes) herbfields particularly on wet substrates (seeps, swamps etc.).
