Gleason : Studies on West Indian Vernonieae 323 



Vernonia leptoclada Sch.-Bip. A specimen agreeing perfectly 

 with the original description has been recently collected by 

 Shafer, 8145, from Camp La Gloria, south of Sierra Moa, Oriente, 

 Cuba. It is described as a straggling shrub 3.5 m. tall, with white 

 flowers. 



Vernonia Wrightii Sch.-Bip. Ex descr. A shrub, 1 m. high, 

 freely branched above; stems pubescent; leaves heavy and coria- 

 ceous, spreading or ascending, ovate-oblong to oblong, 3.5 cm. long 

 by 1.2 cm. wide, sharply acute or mucronate, revolute, entire or 

 with a few remote spinose teeth, rounded or even subcordate at the 

 base, very scabrous above but not pubescent, minutely puberulent 

 under the lens beneath; petioles 1-2 mm. long, pubescent; cymes 

 long and spreading, with numerous heads; bracteal leaves like 

 the cauline, but gradually reduced to 1 cm. long; heads sessile, 

 secund, about 21 -flowered; involucre about 7-8 mm. high, outer 

 scales ovate, acuminate into a squarrose or recurved tip, the inner 

 erect or somewhat spreading, sharply acute or subulate; pappus 

 pale brown. 



Shafer 7738, from a dry serpentine hill near El Yunque, 

 Oriente, and Shafer 3072, from pine lands at 500-650 m. altitude 

 near Woodfred, Oriente, are referred here. They agree in most 

 essential points with Schultz' description of V. Wrightii (Journ. 

 Bot. 1 : 234. 1863), but lack the glabrous leaves narrowed at both 

 ends and the sordid-purple pappus. 



Schultz' species is based on Wright 1309. As is well known, 

 the Wright numbers are much confused, and frequently .shelter 

 more than one species. The only available specimen of this 

 number belongs to an entirely different species. 



Vernonia Sagraeana DC. A shrub 1.5 m. tall, growing on 

 banks at an altitude of 325 m., near El Cuero, Oriente, Britton & 

 Cowell 12794. 



Vernonia aronifolia sp. nov. 



Bushy, suffrutescent or shrubby, 12-15 dm. high; stem stout, 

 freely branched, striate, finely and thinly tomentose, the tomentum 

 increasing in density toward the tips of the branches and always 

 most abundant in the axils; leaves dark green, thin but firm, 

 obovate-oblong, about 8 cm. long by 4 cm. wide, abruptly acumi- 

 nate, remotely denticulate with subulate or spinulose teeth 0.5
