A New Species

As part of ongoing efforts to understand and document the flora of the southeastern United States, we propose a number of taxonomic changes. In Trichostema, we name a new species, narrowly endemic to maritime grasslands in the Carolinas and warranting formal conservation status and action. In Dichanthelium (Poaceae), we continue the reassessment of taxa formerly recognized in Panicum and provide new combinations along with a new key to taxa in the Dichanthelium scabriusculum complex. In Paspalum (Poaceae), we address the controversial taxonomy of P. arundinaceum and P. pleostachyum and treat the two as conspecific, with P. arundinaceum the correct name. In Portulaca (Portulacaceae), we report the discovery of the Bahamian P. minuta as a native component of the North American flora, occurring in southern Florida.

Taxonomic Changes

As part of ongoing efforts to understand and document the flora of the southeastern United States, a number of taxonomic changes at generic, specific, and infraspecific rank are made. We also discuss and clarify the recommended taxonomy for other taxa (not requiring nomenclatural acts) and present a point of view about the practical and philosophic basis for making taxonomic changes in an allegedly well-understood flora. The genera (and families) affected are Endodeca (Aristolochiaceae), Erigeron, Pityopsis, and Solidago (Asteraceae), Tillandsia (Bromeliaceae), Carex (Cyperaceae), Baptisia and Indigofera (Fabaceae), Salvia and Scutellaria (Lamiaceae), Stenanthium (Melanthiaceae), Epidendrum (Orchidaceae), and Andropogon, Coleataenia, Dichanthelium, Digitaria, and Panicum (Poaceae).

Taxonomic Changes

As part of ongoing efforts to understand and document the flora of the southeastern United States, we propose a number of taxonomic changes and report a distributional record. In Rhynchospora (Cyperaceae), we elevate the well-marked R. glomerata var. angusta to species rank. In Dryopteris (Dryopteridaceae), we report a state distributional record for Mississippi for D. celsa, filling a range gap. In Oenothera (Onagraceae), we continue the reassessment of the Oenothera fruticosa complex and elevate O. fruticosa var. unguiculata to species rank. In Eragrostis (Poaceae), we address typification issues. In the Trilliaceae, Trillium undulatum is transferred to Trillidium, providing a better correlation of taxonomy with our current phylogenetic understanding of the family.

A New Species

Background and Aims: Cochemiea is a genus which currently comprises five species occurring in Mexico. It is morphologically characterized by cylindrical decumbent to prostrate stems and by a long red-scarlet zygomorphic perianth, presumably specialized for hummingbird pollination. As part ofthe ongoing taxonomic studies on the North Mexican flora, a population discovered by Thomas Linzen in 2012 in central Sinaloa (Mexico), previously identified as Mammillaria sp., actually refers to a Cochemiea species and cannot be ascribed to any of the known species of that genus. As a consequence,we here propose to describe this population as a a new species for science.Methods: The work is based on field surveys (autumn 2018 and spring 2019) in central Sinaloa, examination of herbarium specimens, and analysis of relevant literature. Its conservation status was assessed following the guidelines of the IUCN; AOO and EOO were calculated with the programGeoCAT.Key results: Cochemiea thomasii is described and illustrated from Sinaloa. The new species is morphologically similar to C. halei from which it differs by the hanging stems, the larger conical tubercles, less numerous and shorter central spines, and the ovoid fruits. A diagnostic key of the knownCochemiea species is included.Conclusions: Cochemiea thomasii is endemic to the state of Sinaloa where it occupies a small area. On the basis of the criteria B2a (geographic range) and C (small population) of IUCN, the new species can be assessed as Critically Endangered (CR) or Vulnerable (VU). Adopting the precautionary approach, Cochemiea thomasii is considered as Critically Endangered (CR).

A New Species

A new species, Eucalyptus fusiformis Boland et Kleinig, from the north coast of New South Wales is described. Its taxonomic position is in E. subgenus Symphyomyrtus series Paniculatae following the informal classification of eucalypts proposed by Pryor and Johnson (1971). E. fusiformis is characterised by its flowers, fruits and adult leaves. In the bud the staminal filaments are fully inflected while the androecium has outer staminodes and the anthers are cuboid and adnate. The fruits are narrow, often truncate fusiform, tapering into long slender pedicels. The adult leaves are dull grey, concolorous and hypoamphistomatic. The species resembles the more numerous and often co-occurring ironbark E. siderophloia which has similar adult and seedling leaves. The volatile oils of both species are very similar. The ecology, distribution, taxonomic affinities and conservation status are discussed.

A New Species

The history of the genus Eupithecia Curtis is reviewed, and a preliminary redescription of the genus is proposed on the basis of the Palaearctic, Nearctic and Oriental fauna. Several Asian species previously placed in Eupithecia  have been found to be anomalous. These are examined and some are placed in related genera, two of them new (Pareupithecia and Girida). A further group (the ‘subrubescens’ group) is retained within Eupithecia as a separate species group. The genus Eva Vojnits is redescribed. A new species is described in the genus Mesoptila Meyrick. Descriptions are given of all genera involved, and full lists of taxa included within them, with the exception of Eupithecia itself. Selected adults and genitalia are illustrated. Taxonomic changes proposed in this paper include: new genera Pareupithecia, Girida; new species  Mesoptila murcida; new synonymies, Emmesocoma Warren, 1907 of Mesoptila Meyrick, 1891 and Horisme sternecki Prout, 1938 of Chloroclystis chingana Wehrli, 1926; new combinations Mesoptila melanolopha Swinhoe, 1895, Mesoptila unitaeniata Warren, 1906, Mesoptila deviridata Warren, 1907, Mesoptila excita Prout, 1958, Mesoptila festiva Prout, 1916, Eupithecia eurytera Prout, 1938, Eupithecia chingana Wehrli, 1926, Pareupithecia spadix Inoue, 1955, Girida rigida Swinhoe, 1892, Girida sporadica Prout, 1932; reinstated taxon Eupithecia brevifasciaria Leech, 1897; and status change  Girida sporadica Prout, 1932.
