38 REPORT ON TWO BOTANICAL COLLECTIONS FROM 
COMPOSIT A. 
VERNONIA ACUTA, N. E. Brown, sp. n. Rami tomentosi. Folia alterna, brevissime 
petiolata, lanceolata, acutissima vel subpungentia, basi acuta, supra glabra, subtus 
tenuiter et appresse pubescentia, glanduloso-punctata ; petiolus tomentosus. Capitula 
in axillis aggregata, sessilia, sub-10-flora. Involucri squamee 5-6 seriatze, imbricatze, 
lanceolatæ, acuminatz, pungentes, subtomentose, exteriores gradatim minores. 
Achzenia appresse pubescentia. Pappus biserialis, squamis exterioribus linearibus 
acutis quam setis interioribus multo brevioribus. 
Branehlets densely tomentose. Leaves alternate, spreading ; petiole 1-2 lin. long, 
tomentose ; blade 11-2 in. long, 4-3 in. broad, lanceolate, very acute and subpungent at 
the apex, acute at the base, entire, with revolute margins, rather rigid, glabrous above, 
except the midrib, which is pubescent, thinly covered with short adpressed hairs aud 
gland-dotted beneath, with the veins and reticulated veinlets impressed above, prominent 
beneath. Heads in clusters of 3 or 4, sessile in the axils of the leaves at the ends of the 
branchlets, about + in. diam., and about 10-flowered. Involucre-scales in 5-6 series, 
adpressed, lanceolate, acuminate, pungent-pointed, adpressed-pubescent or subtomentose, 
the innermost about 3 lin. long, 4-4 lin. broad, the others gradually smaller. Corolla 
¢ in. long, 5-lobed, with the linear acute lobes of equal length with the tube, glabrous. 
Style-branches only about 4 lin. longer than the stamens. Achenes rather more than 
1 lin. long, adpressed-pubescent. Pappus in two series, white; the outer of numerous 
linear acute scales, the inner of numerous bristles, slightly scabrous, much longer than 
the outer series.

EUPATORIUM RORAIMENSE, N. E. Brown, sp. n. Herbacea, ramis breviter pubescentibus. 
Folia opposita, petiolata, ovato-lanceolata, acuminata, glabra, crenato-dentata, petiolo 
pubescente. Capitula corymbosa, circa 20-flora. Involucri squam:e lineares, acute, 
glabrz. Corolle 5-dentata, glabra, tubo supra medium ampliato, campanulato, 
dentibus ovatis, acutis. Achenia 5-angulata, angulis scaberulis. Pappi setze 
scaberulee, roseo-purpure:e. | 
Stems herbaceous, with a very fine spreading pubescence. Leaves opposite; petiole 
4-6 lin. long, pubescent; blade 1j-23 in. long, i-1 in. broad, ovate-lanceolate, 
acuminate, crenately toothed, with teeth 1-2 lin. broad, glabrous on both sides, rather 
thin and submembranous in texture in the dried state. Corymbs terminal, compact, 
2-23 in. diam., its branches 4-1 in. long, and, together with the slender 11-3 lin. long 
pedicels, pubescent like the stem. Bracteoles almost filiform. Heads about 23 lin. 
diam., about 20-flowered. Involucre-scales 2-seriate, 2-21 lin. long, linear, acute, nearly
