56. E. rorulentum Robinson. Shrub or tree with terete hard- 

 wooded fuscous branches and somewhat fastigiate sordid-tomentose 

 branchlets; leaves opposite suborbicular-ovate, obtuse, serrate except 

 at the cordate base, coriaceous, somewhat 3-nerved from well above 

 the base (but with 1-2 pairs of lesser and pinnately arranged veins 

 between the forking of the lateral nerves and the base), 2-2.8 cm. long, 

 1.5-2 cm. wide, finely reticulated on both surfaces, densely sprinkled 

 w'ith lucid globular sessile glands or resinous atoms but otherwise 

 glabrous above, softly tawny-pubescent and more sparingly atomif- 

 erous beneath; petiole 1-3 mm. long; heads about lO-flowered, 

 clustered in rather dense round-topped corymbs terminating the 

 branchlets; involucral scales 7-10, subequal, lance-oblong, acutish, 

 dorsally tawny-tomentose; florets inferred to be whitish; achenes 

 tapering downward, beset on the angles with shortly stiped glands. — 

 Proc. Am. Acad. liv. 255 (1918). 



Cundinamarca: at Guadalupe, alt. 2900 m., Bros. Apollinaire & Arthur, 

 no. 27 (Gr.). 



Obviously near to E. pninifoJium HBK. of Ecuador, which, however, 

 has longer relatively narrower subentire leaves, rounded but not 

 cordate at base. 



57. E. vacciniaefolium Benth. Low fastigiately branched ever- 

 green shrub 1 m. or less in height; branches rusty-hirsute, very leafy, 

 the internodes exceedingly short; leaves opposite, subsessile, elliptic- 

 ovate, narrowed to an obtuse apex, rounded at base, crenately few- 

 toothed, coriaceous, green on both surfaces, 1-2 cm. long, 5-10 mm. 

 W'ide; petiole 2 mm. long; heads 5-6-flowered, in dense round-topped 

 terminal corymbs; involucral scales oblong, subequal, loosely imbri- 

 cated, ciliolate, the tip and margins often claret-colored; achenes 

 glabrous (Benth.) or hispid on the angles. — PI. Hartw. 200 (1845). 

 E. co7ifertifolium Klatt, Abh. naturf. Ges. Halle, xv. 324 (1882), & 

 in advance reprint p. 4 (1881). 



Cundinamarca: in Cordillera de los Andes, near Bogota Harlweg, no. 1104; 

 in mountains near Bogotd, Holton, no. 310 (Gr.). 

 Without locality: Trlana, no. 3 (Gr.). 



An attracti\'e little alpine undershrub, easily distinguished from the 

 related species by its small thick leaves, which are very close together. 



58. E. fastigiatum HBK. Smooth shrub with angulate ascend- 

 ing leafy branches ; lea^'es opposite, lance-oblong to typically oblong,
