MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[VOL. 10 



seen only Riedel s.n., collected near Borba, a sterile branchlet from a young 

 sapling, if one may judge from the texture and loose reticulation of the leaf, not 

 in agreement with the photograph of the type. Three sheets of cultivated material 

 in the New York Botanical Garden Herbarium were determined by Ducke as 

 Licaria (Acrodiclidium) puchury -major as follows: Ducke 45, Jucabi, Rio Negro, 

 19981, Belem do Para, and Froes 21085, Santa Isabel, Rio Negro. These numbers 

 do not accord with the photograph of the type or description. In leaf-structure, 

 particularly the rather fine reticulation of more or less equal density and prom- 

 inence on both leaf-surfaces, and in the presence of very large flowers, these 

 specimens are precisely the same as those of the Puerto Rican taxon Licaria 

 brittoniana Allen & Gregory, 15 which is cultivated locally for general construc- 

 tion. The fruit and subtending cupule of the two species are very different, the 

 fruit of the Puerto Rican taxon being not more than 15 mm long, oblong with 

 the base and apex more or less rounded, the outer cupule-margin slightly un- 

 dulate, and the inner 3 mm longer and slightly lobed.

Aydendron canella Meissner in DC. Prorir. 15 1 : 90. 1864. 



Type. Acarouany, French Guiana, Sagot 1190 (isotype, st. NY). 



Distribution. Tree to 25 m, reported by Kostermans from the Guianas, 

 Trinidad, and Brazil (Rio Negro). BRAZIL. Territorio Amapa: occasional along 

 Rio Oiapoque near Mecro, opposite Clevelandia 3° 48' N 51° 53' W, Maguire, 

 Tires & Maguire 47092 (fl., fr. NY). 



A seemingly widespread species of the lowland tropics characterized by stout, 

 straight branchlets, those of the current year's growth reddish-brown, the older 

 greyish, and by the flat, extremely coriaceous leaves, extending beyond the 

 terminal, densely flowered inflorescences. The species recalls L. cayennensis, also 

 from the Guianas, but the rusty-verrucose fruit cupules, as contrasted with the 

 smooth cupule of the latter, separate the two.

Aydendron ? cayennense Meissner in DC. Prodr. 15 1 : 95. 1864. 



Vernacular name. Wabaima silberballi (Brit. Guiana). 



Type. Cayenne, French Guiana [Patris 41] (isotype, fr. NY). 



Distribution. Tree reported heretofore from the Guianas, now known to occur 

 in the adjoining area in Venezuela, northwest of British Guiana. VENEZUELA. 

 Territorio Delta Amacuro : infrequent in forest near Rio Toro, Serrania Imataca, 

 Wurdack & Monachino 39680 (fr. NY). BRITISH GUIANA. Semi-Wallaba, 

 semi-marsh forest on white sand, Makauria Creek, Essequibo River, For. Dept. 

 Brit. Guiana 5367 (F 2579) (fr. NY). 



The leaves and general habit of the Venezuelan collection are typical of the 

 species. The short, stout infructescences bear immature fruits longer than nor- 

 mally reported and subtended by cupules sparsely covered with rusty warts.
