34. Vernonia calophylla Gleason, Bull. Torrey Club 40: 
SLA. POTS: 
Stems shrubby, 1 m. high or less, freely and loosely branched, cinereous-puberulent 
below to tomentose among the branches; leaf-blades firm and rigid, ovate to subrotund, 20-25 
mm. long, 13-18 mm. wide, rounded or obtuse, entire, somewhat revolute, rounded or subcord- 
ate at base, dark-green, rugose, and papillose-pubescent above, closely gray-tomentose beneath; 
veinlets prominently reticulate; petioles 1-2 mm. long; heads in the axils of the upper leaves, 
forming cymes 10-16 cm. long, sessile, 18—21-flowered; bracteal leaves resembling the cauline 
but smaller, 10-15 mm. long and more densely pubescent above; involucre campanulate, 5 mm. 
high; scales erect, not closely appressed, somewhat arachnoid-puberulent, especially near 
the apex, the outer narrowly triangular, subulate, the inner linear-oblong, acute; achenes 
pubescent, 2 mm. long; pappus nearly white, the bristles 4 mm., the scales 1 mm. long. 
TYPE LOCALITY: Camp La Gloria, south of Sierra Moa, Oriente, Cuba.

35. Vernonia vicina Gleason, Bull. Torrey Club 40: 317. 1913. 
Stems shrubby, erect, 3-6 dm. tall, sparingly branched, glabrate below, puberulent above, 
closely cinereous-tomentulose among the branches; leaf-blades firm and rigid, spreading, 
dark-green above, elliptic to elliptic-oblong, 3-4.5 cm. long, 1—1.5 em. wide, broadest at or 
near the middle, narrowed to an obtuse or subacute tip and an acute base, entire, somewhat 
revolute, rugose above and papillose-pubescent when young, becoming glabrate with age, 
thinly and closely tomentose beneath; veinlets prominently reticulate; petioles tomentose, 
1-2 mm. long; upper leaves like the lower, but smaller, eventually only 1 cm. long, bearing 
heads in the upper 4 or 5 axils; heads about 26-flowered; involucre campanulate, 5-6 mm. 
high; scales closely imbricate, pubescent or thinly tomentose, the outer subulate, somewhat
