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, Shaferj2j2, growing among rocks near water, Arroyo del 

 Medio, Oriente, Cuba, at 450-550 m. altitude, January 20, 1910,
