achaeniis valde immaturis oblanceolatis ; pappi aristis 2 subaequalibus 
achaenium subaequantibus. — V. diversifolia Britton, Bull. Torr. Bot. 
Club, xix. 150 (1892), not DC. — Coripati, Yungas, Bolivia, April, 
1894, Bang, no. 2135 (type, in Gray Herb.). Though doubtfully re- 
ferred to V. diversifolia DC. by Robinson & Greenman, Proc. Am. 
Acad. xxxiv. 562 (1899), this plant with wingless stem and about 9- 
lobed leaves now seems clearly distinct from that Brazilian species. It 
is nearer V. gigantea Jacq., from which, however, it differs in its more 
numerous rays, more strongly auriculate petioles, harsher pubescence, 
and in many other details. From V. columbiana, here described, it 
differs in its smaller less numerously flowered heads, more developed 
rays, etc. It is also near V. myriocephala Sch. Bip. of Mexico, but 
differs in its more convex inflorescence, scabrous-puberulent stem, nar- 
row elongate and entire bracts, ete. 
Verbesina (§ Lipactinia) oligantha, sp. nov., fruticosa 2-3 m. 
alta ; caule teretiusculo exalato griseo scabrido-puberulo aetate lenti- 
cellis parvis late ellipticis brunneis aspero ; foliis oppositis rhomboideo- 
ovatis 1.2-1.6 dm. longis 5-7 em. latis acuminatis serratis basi cuneatis 
integris utringue viridibus scaberrime puberulis, nerviis lateralibus 
principibus 3-4 plus minusve ex eodem loco (2-3 cm. supra basin) 
oriuntibus, ceteris remotioribus et pinnatim locatis ; petiolo 1-1.5 cm. 
longo crispe et scabride puberulo; cymis compositis planis multicap- 
itulatis densiusculis basi foliaceo-bracteatis, pedicellis filiformibus 
erectiusculis 1-7 mm. longis; capitulis 12 mm. altis 4 mm. diametro 
saepissime 7-floris ; involucri squamis valde inaequalibus, exterioribus 
multo brevioribus ovatis 2-3 mm. longis interioribus oblongis abrupte 
acuminatis 6 mm. longis flosculos amplectentibus ; corollis omnibus tu- 
ulosis flavis ; achaeniis valde compressis obl latis olivaceis in facie- 
bus paulo pubescentibus apicem versus angulo interiori anguste alatis. 
—In granitic soil, Jimalcota, Mexico, altitude 300 m., 18 N ovember, 
1898, E. Langlassé, no. 644 (type, in Gray Herb.). It is clear that this 
species is closely related to V. pauciflora Hemsl. but it differs mark- 
edly in its less conspicuous but more scabrous pubescence, its broadly 
rhomboic-ovate leaves, and in its less herbaceous much smoother 
involucre. :
