P. dadara f. ciliata Yuncker, (H nov. 



A speciei forma typica differt foliis ciliolatis. 

 Leaves bristly ciliolate, but otherwise glabrous. 



TYPE: VENEZUELA: Amazonas: Cerro Huachamacari, Rio Cunucunuma, in- 

 frequent on cliff face in dense valley woodland between Summit Camp and sa- 

 vanna on "East" Ridge, alt. 1800 m, Dec. 8, 1950, bassett Maguire, R, S. Cowan 

 & John J. Wurdack 30041 (NY). 



The constricted stems render the dry specimens very brittle and easily broken. 

 The leaf shape and arrangement, and easily fragmented stems are distinctive 

 characters of this species. It belongs in the subgenus Micropiper which includes 

 only a small number of alternate-leaved species. P. purpurinervis CDC. from 

 Mt. Roraima, also a Micropiper with alternate leaves, differs in its leaf shape, 

 minutely puberulent parts, and shorter spikes. 



Peperomia celiae Yuncker, sp. nov. 



Herba carnosa diffusa; caule glabro vel juvenili dissite crispo-pubescenti; 

 foliis alternis rotundato-ovatis, apice obtusis vel subacutis, basi rotundatis 

 cordulatis subpeltatis, conferte ciliolatis palrnatim 5-7 nerviis, petiolo leviter 

 pubescenti; spicis terminalibus atque [?] axillaribus, pedunculo glabro, drupa 

 oblongo-cylindrica apice obliquo-scutelliformi, stigmate centrali. 



A succulent, spreading herb. Stem glabrous, or slightly crisp-pubescent when 

 very young, 2-3 mm thick when dry, drying glossy and with exfoliating epidermis, 

 the internodes mostly 1-3 cm long. Leaves alternate, round-ovate, with rounded, 

 obtuse, or acutish apex, the base rounded, cordulate, slightly peltate, variable 

 in size, 1.5-3.5 cm wide and 1.5-4 cm long, glabrous above, sparsely crisp- 

 pubescent glabrescent beneath, strongly finely ciliate throughout, the ciliation 

 extending onto the petiole as two hairy lines, palrnately 5- or faintly 7-nerved, 

 the innermost pair of lateral nerves approximating the midrib in the lowermost 

 2-3 mm, the midrib and main lateral nerves finely branched upward and submar- 

 ginally loop-connected, drying firm, glossy, dark, translucent, the petiole 5-10 

 or sometimes 20 cm long, sparingly crisp-pubescent. Spikes terminal and [?] ax- 

 illary, about 2 mm thick and 10-12 cm long, the peduncle to 1 cm long, glabrous, 

 the bracts round-peltate, the drupe oblong-cylindrical, thickening slightly toward 

 the truncate base, about 2 mm long, with obliquely scutelliform apex and central 

 stigma. 



TYPE: VENEZUELA: Amazonas: Serrania Yutaje, Rio Manapiare, rare on 

 northwest ridge of Cano Yutaje, alt. 1500 m, Mar. 1, 1953, Bassett Maguire & 

 Celia K. Maguire 35422 (NY). 



This species belongs in the group of species (Rhynchophorum) having fruit 

 with a scutelliform apex. It differs from all known species in its broadly ovate, 

 cordulate, densely ciliated leaves. It is named for Celia K. Maguire, one of the 

 collectors of the type specimen. 



Peperomia gracilipeduncula Yuncker, sp. nov 



Herba epiphytica sat parva glabra; foliis alternis ellipticis vel elliptico- 

 oblanceolatis, apice abrupte acuminatis, basi cuneatis, septuplinerviis apice 

 ciliolatis; petiolo canaliculate decurrenti-amplectenti; spicis tenninalibus ax- 

 illaribusque, ovario apice obliquo truncato, stigmate subapicali, drupa immatura. 



A comparatively small 5 glabrous^ herbaceous epiphyte, the stems 1.5 mm thick 

 near the base when dry, ascending from a decumbent rooting base to about 10 cm 

 high, the internodes to 1 cm long or occasionally 2 cm. ridged by the decurrent 

 petiole margins. Leaves alternate, elliptic or elliptic-oblanceolate, the apex 

 bluntly pointed, the base cuneate, 1.5-3.2 cm wide and 3.5-8 cm long, or some
