316 GLEASON: STUDIES ON WEsT INDIAN VERNONIEAE 
long by half as wide, obtuse or rounded at the tip, irregularly 
crenulate or subentire, rounded or subcordate at base, dark green 
and thinly but softly pubescent above, densely gray-tomentose 
beneath; petioles 1-2 mm. long; upper and terminal branches 
floriferous and strongly flexuous; bracteal leaves resembling the 
cauline in shape and size; heads single, sessile, 21-flowered ; 
involucre broadly turbinate or campanulate, 5 mm. high, its scales 
all erect or somewhat spreading, very loosely imbricated, puberu- 
lent or glabrous, the outer subulate, the inner narrowly lanceolate 
and long-acuminate with a subulate tip; achenes hirsute; pappus 
nearly white, 4 mm. long. 
For the identification of this obscure species of Swartz we are 
indebted to Dr. Urban. The description above is based on a 
single sheet, Fuertes 655, from the Province of Barahona, Santo 
Domingo, at 350 m. altitude. 
Vernonia desiliens sp. nov. 
Herbaceous, sparingly branched, 3-5 dm. tall; stem rather 
prominently striate, glabrous below, becoming puberulent in and 
near the inflorescence; leaves firm and coriaceous, ovate-lanceolate 
to narrowly elliptical, the largest on the type sheet 8—8.5 cm. long 
and 2.3-2.9 cm. wide, obtuse, entire or obscurely and shallowly 
crenulate, obtuse or rounded at the base, with petioles 1-3 mm. 
long, rugose, glabrous and shining above; veins elevated beneath 
and prominently reticulated, the principal lateral ones strongly 
ascending and almost parallel to the leaf-margin; the interstices 
of the reticulations closely gray-tomentose; cymes apparently one 
or two, terminal and from the upper axils, spreading, 1-2 dm. long, 
very flexuous; bracteal leaves resembling the cauline but narrower 
in shape and gradually reduced in size, oblong or narrowly ellip- 
tical, 3-5 cm. long, 5-12 mm. wide, spreading, those at the ex- 
tremity of the cyme oblong-linear, 2 cm. long; heads sessile, single 
in the axils, 1-2 cm. apart, 21-flowered; corollas purplish; in- 
volucre turbinate, thinly pubescent, 9-10 mm. high; the lower 
outer scales short, minute, triangular, acute and apiculate, and 
closely imbricated; the inner scales much longer, linear-oblong, 
obtuse; achenes strigose-pubescent; pappus light brown, the inner 
series 6 mm. long, minutely barbellate, the outer series 0.5 mm. 
long, somewhat paler. 
Type, Shafer 3232, growing among rocks near water, Arroyo del 
Medio, Oriente, Cuba, at 450-550 m. altitude, January 20, 1910,
