beneath; petiole about 5-10 mm long, densely villous, vaginate to near the blade; 



spikes 3-4 mm thick x 10-13 cm long; peduncle 10-15 mm long, villous; bracts 



stout-clavate with rounded, dome-like apex, brown-hairy; ovary globose, densely 



hairy, the hairs extending part way on the awl-shaped stigmas; fruit not developed. 



CHIMBORAZO: canon of the Rio Chanchan, about 5 km north of Huigra, 1500-1950 m, 

 May 19-28, 1945, E-3439 (TYPE). 



The tree-like habit of growth, densely villous stems and leaves, and espe- 

 cially the ovaries characterize this species. 



Piper futuri Trel. & Yun. Pip. North. S. Am. 310. /. 276. 1950. 



SANTIAGO-ZAMORA ("Oriente"): from Mendez to crossing of Rio Paute, 570-630 m, 

 Dec 14, 1944, E-1507. 



The leaves on this specimen are smaller than those of the type collected in 

 Putumayo, Colombia, but it agrees otherwise. 



Piper piluliferifolium Trel. & Yun. Pip. North. S. Am. 315. /. 281. 1950. 



SANTIAGO-ZAMORA ("Oriente"): Cordillera Cutucu, ca 2° 40' S, 78° W, western 

 side of Cutucu, 870-900 m, Nov 17-Dec 5, 1944, E-1080. 



Piper campii Yuncker, sp. nov. 



Frutex subprostratus; foliis oblique lanceolato-ellipticis, apice attenuate 

 acuminatis, basi subaequilateralibus, supra glabris, subtus ad venas minute 

 hirtulis, a parte infera pinnatim venosis; bracteis subglabratis; ovario globoso- 

 ovoideo, conferte puberulo; stigmatibus sessilibus. 



Sprawling, nodose shrub, to 40 cm high; internodes mostly 2-3 cm long, 

 minutely hirtellous-glabrescent downward, finely ridged; leaves obliquely lance- 

 elliptic, one margin nearly straight, the other curved, the midrib nearer the 

 straight side, 3-4 cm wide x 9-12 cm long, the apex attenuately acuminate, the 

 base narrowing downward, one side about 1 mm shorter and acutish, the longer 

 side narrowly rounded, obtuse, glabrous above, the nerves beneath minutely 

 hirtellous, the margin not ciliate, pinnately nerved with 3 widely spaced nerves 

 on each side of the lower half, with cross-connecting nervules, drying somewhat 

 shiny, papery, translucent; petiole 2-3 plus 1 mm long, hirtellous; spikes slen- 

 der, as yet not mature, 1 mm thick x 2 cm long; peduncle slender, scarcely 1 cm 

 long, minutely hirtellous; bracts somewhat cucullate, subglabrous; ovary globose- 

 ovoid, densely puberulent; stigmas 3, slender, sessile; fruit not matured. 



SANTIAGO-ZAMORA ("Oriente"): above Rio Upano, near junction with Paute, near 

 Mendez, 525-750 m, Nov 13, 1944, E-973 (TYPE). 



This species resembles P. cisnerosense somewhat but differs in the number 

 of nerves, size of spikes, shape of ovary, etc. The puberulent, finely ridged 

 stems, leaf shape, short petioles, glabrate bracts, and puberulent ovaries are 

 distinctive features.
