MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



LVOL. 10 



dentibus exterioribus lineari-oblongis 0.5 mm lbngis extus glanduloso-setulosis. 

 Petala 3.5-4 X 1.2-1.8 mm oblongo-ovata acuta. Stamina isomorphica; filamenta 



2 mm longa ; antherarum thecae 2 mm longae anguste oblongae minute porosae, 

 connectivo non prolongato exappendiculato. Stylus 5-5.5 X 0.3 mm ; stigma sub- 

 capitellatum 0.4 mm diam ; ovarium 3-loculare 2/3-inferum apice in eollum 

 modice glanduloso-setulosum 0.4 mm altum protractum. 



Type. Shrub 1-1.5 m, inflorescence hairs reddish, petals pale pink, anthers 

 yellow, occasional in Clusia scrub forest just south of Camp 3, slopes of Cerro 

 de la Xeblina, Terr. Amazonas, Venezuela, alt. 700 m, 14-16 Nov 1957, Bassett 

 Maguire, John J. Wurdack, d° Celia K. Maguire 42077 (holotype US 2342603). 



L. sanguinea has eglandular inflorescence and hypanthium hairs, petals 2.5- 



3 X 0.4-0.7 mm, and anthers 1-1.5 mm long. All of the secundiflorous 5-merous 

 species (several of which are dubiously distinct) with an aspect similar to L. 

 sanguined and L. nebJinensis have 5-celled ovaries. These include L. longicoma 

 Cogn. (ovary glabrous: Asplund 11369, llaughf 1*10 ). 1.. dichotoma (Don) Cogn. 

 (ovary glandular-setulose), L. granatensis Gleas. (ovary glandular-setulose ; 

 Hdught 1311), L. grandifolia Cogn. (ovary sparsely glandular-setulose; Donnell 

 Smith 6557, Tonduz 9012), L. reversd (DC.) Cogn. (ovary glandular-setulose; 

 TJle 908), and L. francavillana Cogn. (vide infra). Cogniaux' descriptions are 

 at variance with some of the above-cited ovary details, as well as for L. retropild 

 Cogn. (ovary 5-celled, glabrous: Camp E-1419, KtiUp dc Smith 22672) ; for each 

 collection cited by me, several ovary dissections are represented. I have seen no 

 material of L. agrestis (Aubl.) Raddi, apparently a rare French Guiana endemic 

 with (fide Cogniaux) a glabrous 3-locular ovary; from the Macbride photograph 

 (36220), the leaves are very thin, sparsely pubescent, and with notably crenulate 

 margins. 



Leandra francavillana Cogn. 



Examination of a bud of an isosyntype (Spruce 2045, K) showed a 5-locular 

 sparsely setulose ovary. Both this collection and Spruce 2184 (Macbride photo- 

 graph 36230) have immature inflorescences, with the latter collection apparently 

 having slightly denser lower leaf surface pubescence. Schultes &' Cabrera 13917 

 (Mitu, Vaupes. Colombia) and Froes 28211 (Rio Uaupes, Amazonas, Brazil) 

 agree well with Spruce 2184 in leaf pubescence and have mature expanded in- 

 florescences (the primary lateral fruiting branches up to 6-10 cm long). Cardona 

 1329 (VEX), from the headwaters of the Rio Siapa on the Venezuela-Brazil 

 frontier, accords well with Spruce 2045 in inflorescence development. Three re- 

 cent Venezuelan collections have mature foliage pubescence slightly less dense 

 and inflorescence more mature and expanded than the Cardona material, but 

 are certainly conspecific with it: these numbers (Maguire c(' Wurdack 34956, 

 from Piedra Xunca, Rio Xegro ; Maguire, Wurdack, & Bunting 36700, Maguir< . 

 Wurdack, &' Maguire 41943, both from the uppermost Rio Yatua) and Cardona 

 1329 all have 5-celled ovaries. I concur with Macbride 's implied exclusion of this 

 species from the Peruvian flora ; all Loreto and Junin material purporting to be 

 L. francavillana has glandular-strigose hypanthia. 



As compared with L. francavillana, L. divaricata (Xaud.) Cogn. has an in- 

 florescence as wide as or wider than long, a glabrous 3-celled ovary, and smaller 

 (usually) leaf blades which are strigulose or short-strigose beneath only on the 

 primary and secondary veins. Gleason's notes indicate that he included here 



rhamnifolia (Xaud.) Tr. var. macrodon (Xaud.) Cogn.; certainly the Sellow
