Vernacular Names. Hioma Cocuir-ey (Huito Indian, Klug) ; Laurel Rebalsero 

 (Williams). 



Distribution. Tree to 12 m, besides occurring in the type locality found also 

 in the Solimoes River Basin of Brazil and in the sandstone area of southern 

 Venezuela, along tributaries of Rio Orinoco. VENEZUELA. Amazonas: cupule 

 red, fruit green, along Rio Padamo, about 15 km above mouth, Maguire & 

 Wurdack 34727 (fr. NY) ; occasional along Rio Orinoco just above Tamatama, 

 Wurdack & Adderley 43647 (J fl. NY) ; en la margen del Casiquiare, Alto 

 Orinoco, Williams 15179 (fr. F, US). BRAZIL. Amazonas: terra firme, Riosinho 

 Juruema, Rio Jutahy, Froes 21022 (J* fl. F, NY). 



A member of the "bracteata" group of endlicherias bearing large, verticil- 

 late, obovate, acuminate leaves with subcordate bases, the upper surfaces some- 

 what shining and reticulate. Maguire & Wurdack 34727 shows a stout, heavily 

 fruited, glabrescent infructescence to 10 cm in length, borne on a peduncle to 

 20 mm long and 5 mm in diameter. The green, ellipsoid fruits more or less blunt 

 at either end, umbonate at the apex, sharply and conspicuously apiculate, approx- 

 imate^ 2x1 cm, are subtended by shallow, flaring, stipitate, cyathiform cupules, 

 about 12 mm in diameter and 5-7 mm deep, thin-margined, subsessile, seated on 

 a short, thickened pedicel. This is probably the first fruiting material to be noted 

 for the species.
