 Rio Casiquiare just above Capihuara, 100-130 m, Amazonas, Venezuela, J. J. 

 Wurdack & L. S. Adderley 43169A (holotype, £ fl. NY) ; 43169B (isotype, ? 

 fl., fr. NY). 



Distribution. Shrubby tree to 10 m, bearing reddish-yellow or white flowers, 

 or cream tinged with pink, occurring along the Rio Pargueni in Bolivar, and 

 the Rios Orinoco and Casiquiare and their tributaries in Amazonas, Venezuela 

 and possibly extending down into Colombia along the Rio Vaupes from 190- 

 200 m. VENEZUELA. Bolivar : occasional along margins of Rio Pargueni 1-10 

 km above mouth, Wurdack & Monachino 39775 (rf fl. NY). Amazonas: occasional 

 along Rio Siapa near mouth, Maguire & Wurdack 34859 (fr. NY) ; en las 

 margenes arboreadas y periodicamente anegadas del alto Casiquiari, Capihuara, 

 Williams 15682 (fr. A); Cariche, midway between San Antonio and mouth of 

 Rio Cunucunuma, Wurdack & Adderley 43064 (J fl. NY) j en los sitios medio 

 abiertos a lo largo de las lagunas y de las rebalsas, Esmeralda, Alto Orinoco, 

 Williams 15367 (J fl. A). COLOMBIA. Comisaria del Vaupes: orilla del Rio 

 Vaupes, entre Mitu y Miriti, Cuatrecasas 6911 (fr. F), 6914 (fr. US), 6922 (fr.

This species superficially resembles Endlicheria bracteolata (Meissner) Allen, 

 but the narrower leaves with veins not subtriplinerved and the flower-structure, 

 distinctly that of Ocotea at once set it apart. The cupule of Endlicheria encloses 

 the fruits for at least one-third of their length, as opposed to the small, disklike 

 cupule to which the fruit of the present species is attached at the extreme base.
