Peperomia stilifera var. nana Yuncker, var. nov. 



Herba parva, stolonifera; foliis rotundato-ovatis, palmatim 5-nerviis. 



Small, trailing herb; stem about 1 mm thick when dry; leaves round-ovate, 

 mostly 1-1.5 cm wide, palmately 5-nerved; petiole scarcely 1 cm long; spikes up 

 to 5 cm long; peduncle about 1 cm long. 



AZUAY: the eastern cordillera, 1-8 km north of the village of Sevilla de Oro, 2400- 

 2700 m, July 27-Aug 12, 1945, E-4463 (TYPE). 



The smaller size of all parts of the variety is in strong contrast with those 

 specimens which represent the species. This species is readily recognized by 

 the winged ridges on the stems and leaves, and the character of the stiliferous 

 fruits. In the variety the wings are discontinuous, short, and more or less 

 cristate. 



E — Fruit mostly with a Pseudocupule; Leaves 

 commonly Opposite or Verticillate

Peperomia guttulata Sodiro var. puberulenta Yuncker, var. nov. 



Herba pendula epiphytica puberula; caule pergracili. 



A pendent, puberulent, vine-like epiphytic herb with very slender stems. 



AZUAY: the eastern cordillera, 1-8 km north of the village of Sevilla de Oro, 2400- 

 2700 m, July 27-Aug 12, 1945, E-4478 (TYPE). 



The species was described by Sodiro as having stems 2 mm thick and all 

 parts glabrous. The stems of the specimen here described are scarcely 1 mm 

 thick (when dry) and, with the exception of the upper leaf-surfaces, finely but 

 obviously puberulent. The type of P. guttulata has not been seen but from the 

 evidence available this variety appears to be very closely related to it.
