Gleason: Studies on West Indian Vernonieae 313 



nent beneath; petioles 3-4 mm. long; rameal and bracteal leaves 

 similar, but much smaller; inflorescence cylindrical or pyramidal, 

 composed of numerous short, divaricate, irregularly branched 

 cymes, forming a terminal panicle, and bearing each 4-10 sessile, 

 crowded, 8-flowered heads near their tips; involucre narrowly 

 campanulate, 4-5 mm. high, its scales erect, regularly imbricated 

 in several ranks, thinly puberulent or glabrate, the outer ovate, 

 with acute or apiculate tips, the inner oblong, slightly narrowed 

 to a rounded tip; flowers purple to pale lavender; immature 

 achenes densely pubescent; outer pappus pale brown, 0.4 mm. 

 long, the inner brown, 4 mm. long. 



Type, Britton 102, from Morce's Gap, near Cinchona, Jamaica, 

 September 2-10, 1906, in the Herbarium of the New York Botan- 

 ical Garden. Three other sheets in the same herbarium agree 

 with it perfectly and are referred to the same species: Marble 188, 

 from Cinchona, E. G. Britton 3856, from the Blue Mountains, 

 and Britton 4055, from the Parish of St. Thomas. The latter 

 was collected in March ; the achenes are all discharged and the dry 

 and brown involucre is widely open. 



Vernonia reducta sp. nov. 



Shrubby, freely branched above, height not stated; stem 

 striate, glabrate below, becoming puberulent in the inflorescence; 

 leaves spreading, firm, bright green above, paler beneath, narrowly 

 elliptical-oblong or somewhat oblanceolate, broadest at or near the 

 middle, the principal ones 4-4.5 cm. long by 1 .2-1.6 cm. wide, 

 sharply acute or subacuminate, entire or finely denticulate, 

 gradually narrowed at the base, minutely puberulent on both 

 sides and finely glandular-punctate beneath; petioles 2-5 mm. 

 long; cymes numerous, terminating the stem and the upper 

 branches, and forming a large loose pyramidal panicle; rameal 

 and bracteal leaves resembling the cauline, but becoming narrower 

 and smaller toward the ends of the branches, and finally barely 

 exceeding the heads; heads crowded in clusters of 2-7, sessile 

 or nearly so, not at all secund, 5-flowered; involucre narrowly 

 campanulate or subcylindric, 5-6 mm. high, its scales puberulent 

 on the back and regularly imbricated in several ranks, outer scales 

 triangular, acute, and somewhat arachnoid-ciliate, the inner be- 

 coming oblong-linear, puberulent or glabrate, narrowed to an 

 obtuse apex; achenes about 2 mm. long, hirsute; pappus rufescent, 

 the outer series 0.5 mm., the inner 4-5 mm. long.
