A rather large, terrestrial, branched herb, up to 80 cm tall; stems, peduncles, 

 petioles and nerves beneath densely minutely hirtellous; leaves alternate, round- 

 ovate, 10*17 cm wide x 12-21 cm long, the apex rounded or narrowed and sub- 

 acute, the base rounded, cordulate or shallowly cordate, the margins decurrent 

 on the petiole, deep green above with paler intercostal mottling, red or purple 

 beneath when living, 11-nerved, the nerves coalescing within the lowermost 1 cm 

 or subpalmate in small leaves, dark-glandular-dotted by transmitted light; petiole 

 from 5 cm long above to 15 cm or more long on large lower leaves; spikes densely 

 flowered, 2-3 mm thick x 10-15 cm long, occasionally solitary but more com- 

 monly 2-several in elongated, umbellate-paniculate, branch-like clusters with 

 reduced bract-like leaves; peduncle of individual spikes mostly 4-9 cm long; 

 bracts rounded, peltate; fruit globose-ovoid, about 0.8 mm long, the apex bluntly 

 oblique; stigma inconspicuous, slightly subterminal. 



S ANT I AGO-Z AMOR A ("Oriente"): eastern slope of the cordillera, valley of the Rios 

 Negro and Chupianza, on the trail from Sevilla de Oro to Mendez, between St. Elena and

 entering Rio Paute, 2-3 km west of Mendez, 570 m, Dec 13, 1944, E-1470 (TYPE). 



The large plants, large, rounded-ovate leaves, minute pubescence, and type 

 of inflorescence are distinctive characters of this species.

Peperomia disjunctiflora Yuncker, sp. nov. 



Herba glabra; foliis alternis, apice attenuatis acute acuminatis, basi cuneatim 

 decurrentibus, supra minute hirtulis glabrescentibus, subtus glabris, 5-plinerviis; 

 petiolo longitudinaliter costulato; drupa ovoidea; stigmate apicali partito. 



A terrestrial, rhizomatous-assurgent herb, forming large colonies; rhizome- 

 branches brownish, simple, erect, up to 15 cm or more tall, glabrous; internodes 

 from 5 mm long above to 2 cm on the mature rhizome, the leaf-scars raised, con- 

 spicuous; leaves alternate, lance-elliptic, the apex attenuately sharp-acuminate, 

 the base cuneate-decurrent, 1.5-2.3 cm wide x 5-7 cm long, hirtellous-glabrescent 

 above, glabrous and paler beneath, rather obscurely glandular-dotted, 5-plinerved, 

 the nerves coalescing mostly within the lowermost 5 mm, the margin ciliolate 

 upward; petiole mostly 5-10 mm long, glabrous, shallowly channeled, narrowly 

 margined downward by the decurrent blade margins; spikes very slender, mostly 

 4-6 cm long, in the axils of small, leaflike bracts on slender axillary, glabrous, 

 panicle-like branches longer than the subtending leaf, very loosely flowered; 

 peduncle 5-10 mm long, glabrous; floral bracts ovate-orbicular, peltate below the 

 middle; fruit ovoid; stigma apical, divided, pilose.
