6297), Petit Coulibri (Whitcifoord 5996), South Chiltern
(Nicolson 2167), Springfield (King 6333, 6338). Sylvania
(Cooper 24), Tete Morne (King 6322).
Verbesina howardiana
Verbesi~ howardiana J. Olsen, 1989107.
Subshrub with rather succulent stems; leaves clustered near
branch ends, obovate, to 10 cm x 5 cm, the small teeth
glandular; involucral bracts dark brown; ray-florets yellow,
conspicuous, 1.2-1.5 cm long, disk-florets glabrous.
Endemic and new far Dominica in elfm woodlands: Mome
Diablotins (Whitefoord 5309 at BM), Morne Trois Pitons
summit (Chambers 2588, Kimber 975, Nicolson 1815).
Flowering in October, fruiting December.
Guadeloupe, Martinique, and Dominica now each have
endemic montane species of Verbesina. The ariginal publication's
attribution of Dominica's endemic to the Dominican
Republic (Hispaniola) is an unfortunate error.
