Reseda collina is included in Reseda section Phyteuma, a monophyletic and morphologically well-defined group that is also characterized by taxonomic problems regarding species circumscription. The status of this species has been controversial, usually being subordinated to the widespread R. phyteuma. A study of R. collina and allied taxa based on morphological and molecular (nuclear ITS, plastid trnL-F) data supports the taxonomic identity of R. collina and its separation from R. phyteuma. An epitype is designated to support the holotype and prevent future nomenclature problems. In addition, our molecular and morphological analyses suggest that some problematic southeastern Iberian populations, previously identified as R. phyteuma, belong to R. collina, which implies a new European record for this species that was previously considered as a northwestern African endemic. Following this finding, biogeographic relationships between the southern Iberian Peninsula and northwestern Africa are also discussed.
Reseda minoica(Resedaceae), a New Species from the Eastern Mediterranean Region
Annales Botanici Fennici, 2013
Reseda minoica Martín-Bravo & Jim. Mejías (Resedaceae), a new species from the eastern Mediterranean region, is described and illustrated. It is distributed in Crete (Gavdos Island), Cyprus and S Anatolia (Mersin), where it grows mostly on basic, occasionally schistose, substrates near the coast. It is included in Reseda sect. Phyteuma, a taxonomically complex group mostly containing narrow endemics from the western or eastern Mediterranean region. Reseda minoica has been confused with R. odorata, R. orientalis and R. balansae in Crete, Cyprus and Turkey. It can be distinguished from those by the lower number of stamens, seed size, colour of petals and indumentum. An identification key to the eastern Mediterranean taxa of Reseda sect. Phyteuma is provided.
Reseda globulosa (Resedaceae): a new record for the flora of Turkey
Turkish Journal of Botany
The authors carried out extensive field floristic studies in the northeast part of Turkey, collected some Reseda L. specimens from Yusufeli to Olur (Erzurum) road (Artvin district), on calcareous rocks, in Artvin province. The flora of this part of Turkey is particularly interesting as it is characterized with Mediterranean climate although it is located in the Euro-Siberian region. The collected specimens did not match any of the species included in the taxonomic accounts of the Resedaceae for the flora of Turkey (Coode 1965;

The Resedaceae, containing 6 genera and ca. 85 species, are widely distributed in the Old World, with a major center of species diversity in the Mediterranean basin. Phylogenetic analyses of ITS and plastid trnL-trnF sequences of 66 species from all genera of the Resedaceae reveal (1) monophyly of the family, in congruence with preliminary phylogenetic studies; (2) molecular support for the traditional morphological subdivision of the Resedaceae into three tribes according to ovary and placentation types, and carpel number; (3) two monophyletic genera (Caylusea, Sesamoides), and one natural group (core Reseda), which includes the remaining four genera of the family (Ochradenus, Oligomeris, Randonia, Reseda); (4) a monophyletic origin for four of the six taxonomic sections recognized within Reseda (Leucoreseda, Luteola, Glaucoreseda, Phyteuma). Our results lead us to interpret an increment of the basic chromosome number in the family from x D 5 to x D 6 in at least two independent in...

Our results lead us to interpret an increment of the basic chromosome number in the family from x D 5 to x D 6 in at least two independent instances, and a broad representation of polyploids in multiple lineages across phylogenies, including association between octoploids and alien invasion in many parts of the world. Species diversity, endemism number, phylogenetic relationships and sequence divergence in Resedaceae suggest two major centers of diVerentiation, one in the western Mediterranean, and the other in the eastern Mediterranean and SW Asia. Two independent colonization events to the Canary Islands from Africa are indicated for the two Canarian Reseda endemics.
A study on the autecology of Reseda lutea L. (Resedaceae) distributed in Western Anatolia
Turkish Journal of Botany, 2001
The aim of this study was to determine the autecological characteristics of Reseda lutea L. (Resedaceae) distributed in Western Anatolia. The chemical and physical analysis was carried out on soil and plant samples collected from 54 different localities in Western Anatolia. The results show that the plant generally prefers sandy-loam and sandy-clayey-loam textural soils, with a slightly alkaline or medium alkaline pH. They prefer non-saline, calcareous soils which are poor in potassium and phosphorus, but the nitrogen content of the soils was found to vary greatly. The soil and plant analysis results were evaluated statistically and correlations were established.

A study on Reseda lutea L. distributed naturally in West Anatolia in Turkey
Acta Botanica Croatica, 2002
Morphology and seed germination of Reseda lutea L. (Resedaceae), which is distributed naturally in Turkey, were investigated. Germination trial was observed at 10, 15, 20, 25, 30, 35 and 40 °C. In laboratory conditions at 25 °C, 87% of the seeds of R. lutea germinated, while in soil conditions, the best germination rate was only 23%, achieved with seeds sowed at 10 mm depth. The results of germination under different light conditions showed that the germination rate at 25 °C in continuous darkness was 87%, 76% with 6 hours of light, 67% with 12 hours of light, 52% with 18 hours of light and 42% with continuous light. Measurements of samples collected from different localities showed that the length of the plant is inversely proportional to the altitude.
Pollen morphology of some Turkish Ajuga L. (Lamiaceae) and its taxonomic value
Bangladesh Journal of Botany, 2011
Pollen morphological structures of eight Turkish species of Ajuga, namely A. bombycina Boiss., A. chamaepitys (L.) Schreber ssp. chia var. chia (Schreber) Arcangeli, A. chamaepitys (L.) Schreber ssp. chia var. ciliata Briq., A. chamaepitys (L.) Schreber ssp. cuneatifolia (Stapf) P. H. Davis, A. genevensis L., A. laxmannii (L.) Benthum, A.orientalis L. and A. reptans L. have been studied under light and scanning electron microscopes for the first time. It is revealed that the pollen grains of Ajuga taxa are more or less suboblata-subprolata and tricolpatae. The exine sculpture is granulate in A. chamaepitys subsp. chia var. chia, A. chamaepitys subsp. cuneatifolia, A. genevensis, A. laxmannii, A. orientalis and A. reptans, but it is reticulate in A. bombycina and A. chamaepitys subsp. chia var. ciliata.
