  • 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.
