Huila: around Iluila, an Indian village in the Hio Paez valley, Ticrra 

 Adentro, alt. KiOO-l'JOO ni., I'itticr, no. 1245 (Gr.). 



Caxjca: Quebrada de Dolores, alt. 1800 m., Andre, no. 2832 (Gr.).

65. E. celtidifolium Lam. Shrub or slender tree with slender 

 grayish stems and spreading pale-green to dull ivory-white branches, 

 glabrous to the inflorescence; leaves opposite, ovate-oblong, caudate- 

 acuminate, thin, firmish in texture, green and glabrous on both sides 

 or slightly pubescent on the nerves beneath, serrate-dentate, 1-1.5 dm. 

 long, 3-5 cm. wide, 3-nerved from well above the base and with small 

 intramarginal as well as transverse veins; panicles terminal and to 

 some extent lateral; heads small, about 11-flowered; involucre 

 narrowly campanulate, 2.7 mm. high; scales about 10, oblong, ob- 

 tusish, subequal (usually 1-2 of the outermost lanceolate and much 

 shorter) ; florets much exserted ; corollas white. — Encyc. ii. 406 

 (1786); Hook. f. & Jacks. Ind. Kew. i. 916 (1893), where attributed 

 to Colombia. Mikania verrucosa Spreng. Syst. iii. 423 (1826). 



[Var. typicum. Pedicels and branches of the inflorescence glabrous; 

 achenes hispid on the angles but nearly or quite glabrous on the faces]. 



[Lesser Antilles, e. g. Martinique, Guadeloupe, Dominica.] 



Var. hirtellum Robinson. Pedicels and branches of the inflores- 

 cence puberulent; leaves A\ath traces of pubescence at least on the 

 midnerve beneath; achenes hirtellous on the faces as well as the ribs. —

Magdalena: at Minca, Prov. Santa Marta, alt. 915 m., Schlim, no. 909 

 (K., phot. Gr.); locally common in dry forest near Bonda, below 150 m., 

 H. H. SmitJu no. 525 (Gr., Mo.). 



It is probably to this hirtellous form that the Index Kewensis refers 

 in accrediting the species to " N. Granat." E.xcept in the matter of 

 pubescence the plant of Colombia agrees closely with typical material 

 from the Antilles.

 foliage yellow-green; stems thick, pithy, tawny-woolly; internodes
