MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[VOL. 10 



Type. Tree 6 m high, in mixed high forest near Base Camp, Cerro Sipapo 

 (Paraque), 125 m, Amazonas, Venezuela, 17 Jan 1949, Bassett Maguire & Louis 

 Politi 28428 (holotype, <$ fl. NY). 



Distribution. Tree up to 10 m occurring in the Rio Orinoco and Guainia areas 

 of southwestern Venezuela in high, moist forests of the Guayana Highlands above 

 the flood plains at an altitude of about 125 m. VENEZUELA. Amazonas: en la 

 selva alta tupida, fuera de las inundaciones, Maroa, Rio Guainia, Williams 14370 

 (fr. A, US). 



This large, obovate-leaved species, which belongs to the distinctive "brae- 

 teata" group, is distinguished by the unusual feature of the veins which 

 consistently arise nearly at right angles from the midrib, very gradually arching 

 towards and becoming confluent at the margin. The species is near and possibly 

 may bear a varietal relationship to the Peruvian E. tessmannii O. C. Schmidt.

This represents another variation in the "bracteata" group quite distinct 

 from all others in having usually small, definitely elliptic leaves more roughly
