achaeniis valde immaturis oblanceolatis ; pappi aristis 2 subaequalibus 

 achaenium subaequantibus. — V. diversifoUa Britton, Bull. Torr. Bot. 

 Club, xix. 150 (1892), not DC. — Coripati, Yungas, Bolivia, April, 

 1894, Bajig, no. 2135 (type, in Gray Herb.). Tbough doubtfully re- 

 ferred to V. diversifoUa 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, etc. 



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 cm. latis acuminatis serratis basi cuneatis 

 integris utrinque viridibus scaberrime puberulis, nerviis lateralibus 

 prineipibus 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 ; coroUis omnibus tu- 

 bulosis flavis ; achaeniis valde compressis oblanceolatis olivaceis in facie- 

 bus paulo pubescentibus apicem versus angulo interiori anguste alatis, 

 — In granitic soil, Jimalcota, Mexico, altitude 300 m., 18 November, 

 1898, E. Langkisse, no. 644 (type, in Giay Herb.). It is clear that this 

 species is closely related to V. paucijlma 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. 



Calyptocarpus blepharolepis, sp. nov., annuus prostratus multi- 

 caulis et fere a basi patente oppositirameus ; caulibus ramisque gracilibus 

 teretibus striatulis flexuosis cum pilis albis hirsutulo-pubescentibus 

 plerumque bis bifurcatis ; internodiis saepe longissimis ; foliis oppos- 

 itis petiolatis spatulato-obovatis integris apice rotundatis mucronulatis 

 utrinque cum pilis albis basi incrassatis strigosis 2-2.5 cm. longis 

 1.1-1.4 cm. latis subtus distincte pallidioribus, petiolis I cm. longis hir-
