Many of the sheets are from the non Ohio holdings of Oberlin College (OC). A brief history of the MU collection and a complete listing of the specimens are given, with annotations correcting mistakes in protologues or monographic accounts involving a few of the specimens.

Nakai (Moraceae) is reported from Ohio, from outdoor sites in Butler, Franklin, and Washington counties, and from greenhouse sites in Athens, Butler, and Hamilton counties. The species was first found in the state in 1979, but has not previously been reported in floristic literature for Ohio. It probably entered the state through greenhouses and nursery stock from which it escaped into weedy areas and flower beds. It persists in outdoor situations in the state and is likely to become a common weedy species in Ohio. An illustration is included for the first time in North American botanical literature. OHIO J. SCI. 93 (5): 147-149, 1993 INTRODUCTION Fatoua villosa (Thunb.) Nakai, an herbaceous member of the Moraceae, was collected by the author in 1992 in Butler County, OH, in both greenhouse and outdoor sites. A search of herbaria in the state and vicinity revealed two previous collections of the species from Ohio, one from Hamilton County in 1979, and the oth...

Populations ranged in size from 75–100 individuals. The species is rarely collected, perhaps due to its unobtrusive habit and small size, and may be sought in similar habitats in late summer.

Included are seven new genera and 49 new species and subspecies, representing 10 families. Of these, the following genera are first reports for the state: Calibrachoa, Callicarpa, Cyclospermum, Dittrichia, Hippophae, Photinia, and Sideritis. None of the discoveries included in this work represents a new family for Ohio. Also included are noteworthy finds and discussions of taxa deleted from the flora and from county records, along with our rationale for each change.

Tumble windmill grass (also known as windmill grass and finger windmill grass) is a tufted perenn... more Tumble windmill grass (also known as windmill grass and finger windmill grass) is a tufted perennial species growing from 10 to 40 cm tall. Its stems are erect to decumbent, often strongly jointed at the nodes, with flattened sheaths, and often rooted at the nodes. The leaves are often concentrated at the base of the stem, with flat blades ranging from 4 to 15 cm in length and 2 to 4 mm wide. Inflorescences of the species are purple to pinkish, when young consisting of upwardly pointed branches emerging from a folded leaf at the tip of the stem. As the inflorescence emerges, the branches flatten out to a verticillate arrangement of 2 to 4 or more whorls of branches, giving the species its characteristic appearance (Fig. 1a). The inflorescence measures from 15 to 28 cm in width at maturity, and up to 15 cm from the lowest whorl of branches to the upper tip. The spikelets (Fig. 1b), composed of 2 glumes and 1 fertile (lower) floret and 1 sterile (upper) floret, measure about 3 mm in length, with an awn up to 10 mm in length at the tip of each lemma. As the fruits mature, the inflorescence fades to straw-colored or slightly pink, often breaking loose from the plant and being blown around by wind. The spread of Chloris verticillata from its historical range appears to have several causes. First, the species may have expanded its range naturally due to the wind-borne nature of its inflorescence, which can be blown around quite effectively by strong winds (personal observation). Secondly, the interstate highway system may play a role in its distribution, as may rail lines. The species may be weedy or invasive in at least some regions of the United States (e.g., Kansas, problem weed in lawns [Haddock 2004]; Michigan, considered a widespread non-native species [Michigan Association of Conservation Districts 2004]; Nebraska, considered invasive [Stubbendieck et al. 1994]; US Forest Service East

The most abundant oil components were the monoterpenoids α-pinene (24.7%), α-terpineol (13.8%), and trans-pinocarveol (11.6%). The antimicrobial activity against Bacillus cereus, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, and Aspergillus niger, and the in-vitro cytotoxicity of the oil on Hep G2, MDA-MB-231, Hs 578T, and PC-3 human tumor cells were also examined.
