Piper mendezense Yuncker, sp. nov. 



Frutex glaber; foliis lanceolatis vel oblongo-ellipticis, apice acute-acumi- 

 natis, basi aequilateralibus acutis decurrentibus, omnino pinnatim venosis; 

 petiolo ad laminam vaginato-alato; ovario ovoideo substyloso; stigmatibus 

 parvis. 



Shrub 1.5 m tall, glabrous; upper internodes moderately slender, 3-6 cm long, 

 gray-granular; leaves lance- or oblong-elliptic, the apex sharp-acuminate, the 

 base equilateral, acute, decurrent, 3.5-5 cm wide x 10-13 long, gray-granular 

 on both sides, pinnately nerved throughout, the nerves 6-8 on each side, with 

 intermediates, the anastomosing nervules small, obscure, with numerous intra- 

 aerole contorted branches, drying firm, opaque; petiole 8-20 mm long, the lower, 

 longer ones vaginate-winged to the blade; spikes as yet young, 3 mm thick x 12 

 mm long, apiculate; peduncle 5 mm long; bracts triangular-subpeltate, marginally 

 fringed; ovary ovoid, with pointed, substylose apex; stigmas ligulate; fruit not 

 mature. ; 



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

 near Mendez, 525-750 m, Nov 13, 1944, E-962 (TYPE). 



The glabrous branches and leaves, leaves pinnately nerved throughout with 

 contorted intra-aerole nervules, and substylose ovaries are distinctive characters 

 of this species. 



Piper ieticianum CDC. var. nanum Yuncker, var. nov. 



Frutex; foliis supra glabris, subtus longe villosis; stylo crasso; stigmatibus 

 subligulatis brevibus. 



Small shrub 1 m tall; leaves 2.5-4 cm wide x 10-12 cm long, glabrous above 

 and long-villous beneath, at least along the nerves; stigmas short, subligulate, 

 on a stout style. 



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

 side of Cutucu, 870-900 m, Nov 17-Dec 5, 1944, E-1082 (TYPE). 



From var. tessmannii of Peru, which is also glabrous on the upper leaf sur- 

 face, it differs in its smaller leaves with acute rather than rounded bases. 



Piper Ieticianum CDC. var. longispicum Yuncker, var. nov. 



Foliis supra glabris, subtus conferte villosis: stylo crasso. 



Leaves glabrous above, densely villous beneath, 2.5-4 cm wide x 10-12 cm 

 long, with 8-10 nerves on each side, with intermediates and cross-connecting 

 nervules; spikes 5 cm long; fruit with a stout, obvious style.
