The typification and nomenclature pertaining to Funastrum heterophyllum (Engelm. ex Torr.) Standl. are reviewed. The legitimacy of several synonyms pertaining to this species is discussed. A revised and complete synonymy is provided.
Biodiversity is as important as climate to a healthy, sustainable and prosperous planet. For Erik Solheim, the head of the United Nations Environment Program, biodiversity has to be protected therefore for spiritual, ecosystem, and economic reasons. The climate in northeastern North America is also influenced, especially in winter, by a fourth air mass: the cold, moist oceanic North Atlantic air mass generated by the waters off Newfoundland, Labrador, and Greenland. The northern half of the continent is covered with deposits such as tills and moraines that reflect the action of the ice sheets on the terrain. Grassland vegetation is dominated by herbaceous plants that form one or two canopy layers. Woody plants are restricted to local areas of distinctive topography, soil, or protection from fire. A central section, much richer in tree species, extends from the southern Alaska–British Columbia border to the Oregon-California border.
Recent systematic treatments for Jamaica have shown that the island is home to seven endemic genera of seed-plants [viz., Dendrocousinsia (Euphorbiaceae), Jacmaia (Asteraceae), Odontocline (Asteraceae), Portlandia (Rubiaceae), Salpixantha (Acanthaceae), Tetrasiphon (Celastraceae), and Zemisia (Asteraceae)]. These taxa account for over 23 species, with three genera (Jacmaia, Tetrasiphon, and Zemisia) being monotypic. Further study of these taxa revealed that five names need typification: (1) Tetrasiphon jamaicensis Urb.; (2) Senecio fadyenii Griseb.; (3) S. fadyenii var. dolichanthus Krug & Urb.; (4) S. hollickii Britton ex Greenm. [all the three Senecio taxa included in Odontocline]; and (5) Gymnanthes elliptica Sw. Lectotypes for these names are designated here. Furthermore, G. elliptica is transferred to Dendrocousinsia and the new combination is made here: D. elliptica (Sw.) Commock & K. Wurdack
A new name, Piptochaetium fuscum, is provided for a taxon hitherto known as Piptochaetium setosum (Trin.) Arechav. Morphological, anatomical, and molecular studies that argue against including Piptochaetium in Stipa, and hence use of S. purpurata (Phil.) Columbus & J.P. Sm., are cited.
