38 REPORT ON TWO BOTANICAL COLLECTIONS PROM 



COMPOSITE. 



Vernonia acuta, X. E. Brown, sp. n. Rami tomentosi. Folia alterna, brevissirne 



petiolata, lanceolata, acutissiina vel subpungentia, basi acuta, supra glabra, subtus 



tenuiter et appresse pubescentia, glanduloso-punctata ; petiolus tomcutosus. Capitula 



in axillis aggregata, sessilia, sub-10-flora. Involucri squamae 5-6 seriate, inabricatae, 



lanceolatse, acuminata 1 , pungentes, subtomentosae, exteriores gradatim minores. 



Achaenia appresse pubescentia. Pappus biserialis, squamis exterioribus linearibus 



acutis quam setis interioribus multo brevioribus. 



BrancMets densely tomentose. Leaves alternate, spreading ; petiole 1-2 lin. long, 



tomentose ; blade 1^-2 in. long, \-\ iu. 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 pubesceut, thinly covered with short adpressed hairs and 



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 



brauchlets, about J 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, -|-f 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 \ 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.

Ireng Valley, McConnell 8f Quelch, 211, 304. 



Etjpatorium roraimense, N. E. Brown, sp. n. Herbacea, ramis breviter pubescentibus. 



Polia opposita, petiolata, ovato-lanceolata, acuminata, glabra, crenato-dentata, petiolo 



pubescente. Capitula corymbosa, circa 20-fl.ora. Involucri squamae lineares, acutae, 



glabra?. Corolla? 5-dentata, glabra, tubo supra medium ampliato, campanulato, 



dentibus ovatis, acutis. Achsenia 5-angulata, angulis scaberulis. Pappi setae 



scaberula?, roseo-purpureoe. 



Stems herbaceous, with a very fine spreading pubescence. Leaves opposite ; petiole 



4-6 lin. long, pubescent ; blade lJ-2^ in. long, |-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, 



2-2f in. diam., its branches \-l in. long, and, together with the slender 1^-3 lin. long 



pedicels, pubescent like the stem. Bracteoles almost filiform. Heads about 2h lin. 



diam., about 20-flowered. Involucre-scales 2-scriate, 2-2] lin. long, linear, acute, nearly
