[VOL. 10 



puberulis ca. ad medium pinnatim venosis nerviis utrinque 8-9, petiolo ad 

 laminam vaginato-alato ; spicis valde apiculatis, bracteis triangulari-subpeltatis 

 margine conferte fimbriates, drupa oblonga angulata glabra apice depresso- 

 truncata, stigmatibus parvis sessilibus. 



A branching subshrub 1-2 m high ; upper internodes stout, up to 12 cm long, 

 glabrous, glandular-granular and dark when dry. Leaves broad-elliptic, the apex 

 abruptly and narrowly somewhat falcately acuminate, the base subequilaterally 

 rounded, cordulate, glabrous above, the nerves beneath appressed-puberulent, 

 glabrescent, the midrib glabrate toward the base, appressed-puberulent upward, 

 11-14.5 cm wide and 20-25 cm or more long, pinnately nerved to about the 

 middle, the nerves 8 or 9 on each side, subequidistantly spaced with the exception 

 of the lowermost 3 or 4 pairs and the uppermost slightly more distant pair, 

 prominent beneath, with conspicuous cross-connecting-anastomosing nervules, the 

 areolas strongly angular as viewed by transmitted light, drying green above, 

 brown beneath, chartaceous, translucent, pellucid-dotted; petiole stout, 2.5-4 cm 

 or more long, glabrous, vaginate-winged to the blade, the wings deciduous. Spikes 

 4 mm thick and 9.5 cm long, strongly apiculate, the point 2-5 mm long, 

 puberulent, the peduncle stout, about 1.5 cm long, glabrous, the bracts triangular- 

 subpeltate, densely marginally fringed, the drupes annularly arranged, oblong, 

 laterally compressed and angular, glabrous, with truncate-depressed apex and 

 small, sessile stigmas. 



Type. Cerro de la Neblina, Rio Yatua, Amazonas, Venezuela, locally frequent 

 in talus forest between Camps 3 and 4, alt. 900-1000 m, 8 Nov 1957, B. Maguire, 

 John J. Wurdack & Celia Maguire 42007 (holotype, NY ) . 



The leaf shape and size, numerous nerves more or less puberulent beneath, 

 abruptly acuminate apex and apiculate spikes characterize this species. It bears 

 considerable resemblance to P. glabrescens (Miquel) C. de Candolle, but differs in 

 having more numerous lateral nerves, stouter and longer spikes, etc. It is named 

 for one of the collectors. 



Piper subduidaense Yuncker, sp. nov. 



Suffrutex, caule glabro; foliis ellipticis vel elliptico-ovatis apice acuminatis 

 basi subaequilateraliter acutis supra glabris subtus crispo-puberulis conferte 

 ciliatis glanduloso-punctatis ad medium pinnatim venosis, nerviis utrinque 5-6 ; 

 bracteis triangulari-subpeltatis luteo-fimbriatis, drupa glabra glanduloso-punctata 

 obpyramidali-trigona apice depresso-truncata, stigmatibus sessilibus. 



A nodose, branching, soft-wooded shrub up to 1.5 m high; stem glabrous, 

 the upper internodes 3-8 cm long. Leaves elliptic or elliptic-ovate, the apex 

 acuminate, the base subequilateral, acute, one side slightly shorter at the petiole, 

 the upper leaves 5.5-7 cm wide and 12-16 cm long, the lower leaves up to 11 cm 

 wide and 21 cm long, glabrous above, crisp-puberulent beneath with the nerves 

 more densely so, prominently ciliate, glandular-dotted, pinnately nerved to about 

 the middle, the nerves 5 or 6 on each side, with cross-connecting-anastomosing 

 nervules, drying chartaceous, translucent, pellucid-dotted ; petiole glabrous, 5 mm 

 long on the upper leaves and vaginate below the middle, 2-3 cm long on the 

 lower leaves and vaginate-winged to about the middle. Spikes 3 mm thick and 

 up to 10 cm long, the peduncle up to 2.5 cm long, puberulent near the spike, 

 glabrous below, the bracts triangular-subpeltate, yellow-fringed, the ovary 

 globose-ovoid, the fruit glabrous, glandular-dotted, obpyramidal-trigonous, with 

 truncate-depressed apex and sessile stigmas.
