 obliterans, ser I & II ad 0.5 mm longis, antheris ovatis quam stipite satis robusto 

 triplo longioribus, ser III ad 0.5 mm longis, glandulis quam antheris obovatis

Type. Small tree, flowers white, occasional in Clusia scrub forest just south 

 of Camp 3, Cerro de la Neblina, Amazonas, Venezuela, 700 m, 14-16 Nov 1957, 

 Bassett Maguire, John J. Wur clack & Cclia K. Maguire 42059 (holotvpe, J 1 

 fl. NY). 



Distribution. Known from the type locality and possibly from Cerro Yapa- 

 cana, Rio Orinoco, Amazonas, Venezuela, and the Brazilian Amazon Basin. 

 VENEZUELA. Amazonas: occasional in Savanna No. 3, at northwest base of 

 Cerro Yapacana, Rio Orinoco. Bassett Maguire, John J. Wurdack & George 8. 

 Bunting 36585 (J fl. NY). BRAZIL. Amazonas: Manaos, Estrada do Aleixo, 

 silva secus rivulum loco paludoso, Ducki 1737 (J* fl. NY) . 



The Ducke specimen agrees entirely with the type; the Yapacana material 

 differs in having elliptic leaves up to 15 cm Long, with an obtusely acute or 

 abruptly obtusely acuminate apex. This number bears pistillate Mowers similar 

 in structure to the staminate, except for the larger gynoecium. A single young 

 fruit borne on a slightly thickened rachis appears almost completely enclosed 

 in the cyathiform cupule which equals the thickened stipe. There is a difference 

 in the leaves of the pistillate specimen (36585) which more ample material may 

 lessen by presenting intermediate forms. On the contrary, -the converse may be 

 true and two taxa presently found to exist. 



Ocotea basirecurva C. K. Allen, sp. nov. Fig. 47. 



Arbor ad 10 m alt., gemmis robustis (in ramulis fructiferis) ovoideis attenuate 

 acutis atro-rubris glabris, ramulis robustis angulatis rubris glabris ad apicem 

 nitidis. Folia alternata, petiolis robustissimis atro-rubris brevibus ad 2 mm 

 longis et ad 6 mm latis ad basim intumescentibus, laminis utrinque glabris, 

 pereojaaceis obovatis vel late ellipticis, (13-) 15-20 cm longis et (7.5-) 8.5-11 

 cm latis, ad basim decurrentibus auriculato-recurvatis, ad apicem obtuse acutis 

 rotundatis penninerviis, costa utrinque robusta supra leviter subtus prominenter 

 elevata ad basim conspicue lata, ad 5 mm, nervis 8-10-paribus utrinque prom- 

 inentibus, ad angulo 45° divergentibus. Inflorescentia floresque ignoti. Infructes- 

 centia robusta, ad 20 cm longa, multifructifera, glabra, pedunculo ad 7 cm longo. 

 Fructus immaturus viridis. ? obovoideus, apiculatus, ad 10 X 6-7 mm, cupula 

 vadosa, campanulata, 6-dentata, ad 8 mm longa, ±10 mm diam., et ±1-3 mm 

 alta, pedicello incrassato obconico aequanti subtenta. 



Type. Tree 10 m, with leathery leaves, fruit wholly green, occasional in right 

 branch of Cano Yutaje, Cerro Yutaje, Serrania Yutaje, Rio Manapiare, Ama- 

 zonas, Venezuela, 1300 m, 9 Feb 1953, Bassett Maguire & Celia K. Maguire 

 35096 (holotype, fl. NY). 



This distinctive tree with large auriculate leaves does not resemble any 

 recognized species at hand in the flowering stage. Just possibly this may be later
