up to 18 cm long, bearing minute flowers supported by filamentous pedicels often 

 over 2 cm in length. 



Endlicheria arunciflora (Meissner) Mez, Jahrb. Bot. Gart, Berlin 5: 131. 1889. 



Ampelodaphne arunciflora Meissner in DC. Prodr. 15 1 : 81. 1864. 



Type. Prope San Carlos, ad Rio Negro, Amazonas, Venezuela, Spruce 3061 

 (isotypic? fl. NY). 



Infructescentia robusta, glabra glabrescensve, brunnea, rugulosa, ut videtur 

 racemoso-paniculata, 10-15 cm longa, pedunculo crasso ad 4 cm longo. Fructus 

 viridis, oblongo-ellipsoideus, apiculatus, apice basique ± obtusus, ad 25 X 13 mm, 

 cupula lignosa cyathiformi in sicco ferrugineo-rubra, ad 12-16 mm longa, 15 

 mm diam., et 4-5 mm alta, stipite robusto, ad 6 mm longo et 4 mm lato, pedicello 

 brevi, crasso, ad 2-7 mm longo. 



Distribution. A small to medium-sized tree with stiffly coriaceous, lanceolate 

 or elliptic, rarely oblanceolate, verticillate leaves distinctly glaucous on the lower 

 surface, occurring on sandstone in the vicinity of Rio Orinoco and Rio Negro 

 and their tributaries, in Venezuela at 110-150 m, and reported as well from 

 Loreto, Peru. VENEZUELA. Amazonas: occasional along Cano Tamatama (a 

 black-water cano on right bank of Orinoco just above Tamatama), Wurdack & 

 Adderley 43153 (fr. NY), along Rio Yatua between mouth and Laja Catipan, 

 43435 (J 1 fl. NY) ; inundado en las rebalsas arboreadas del Cano Pendare, 

 Capihuara, Alto Casiquiare, Williams 15738 (st. A). 



The. fruit of this species has not heretofore been recognized. The unusually 

 coriaceous leaves, early extremely glaucous, later becoming less so, with the deeply 

 impressed although slender veins, the confluence of which 3-5 mm from the 

 margin forms a pattern similar to that found frequently in the genus Plcuro- 

 thyrium, are all characteristics indicating that the above-cited numbers belong 

 to E. arunciflora.

Ampelodaphne macrophylla Meissner in DC. Prodr. 15 1 : 81. 1864. 



Type. In vicinibus Barra, Rio Negro, Amazonas, Brazil, Apr 1851, Spruce 

 1453 (isotype J* fl., fr. NY) ; Riedel 1411 (isotype, fr. NY). 



Distribution. Tree to 15 m, occurring chiefly along the Amazon River and its 

 tributaries, reported from the vicinity of Rio de Janeiro and possibly occurring 

 in savannas in the sandstone area along the Rio Orinoco in Amazonas, Venezuela. 

 VENEZUELA. Amazonas : in Savanna No. 3, northeast base of Cerro Yapacana, 

 Rio Orinoco, Maguire, Cowan & Wurdack 30601 (fr. NY). 



The specimen cited above bears inf ructescences with fruits obviously attacked . 

 by galls. In all probability it belongs with this species, for it displays the variable 

 characteristics of the leaves of the type specimens, and the fruit-cupules, although 

 borne on slightly longer pedicels, are similar. 



Endlicheria cocuirey Kostermans, Meded. Bot. Mus. Utrecht 42 : 522. 1937. 



Type. Tree 4 m, flowers white, forest riverside, Florida, Rio Putumayo, at 

 mouth of Rio. Zubineta, Loreto, Peru, about 180 m, May-Jul 1931, G. Klug 2253 

 (isotype, <? fl. NY).
