 fructu maturo obpyriformi valde transverse rugoso, 5-6 em longo; stigmatibus

VENEZUELA: Bolivar: Cerro Guaiquinima, occasional along open watercourse, North 

 Valley; alt. 1600-1700 m; tree 10 m high, stems sharply 4-aiigled; latex clear, yellowish, 

 scanty; petals pink or rose with lacquer-red centers; stigmas 5, sessile; fruit oblong, 6-7 cm

5. Clusia densinervia Cuatr. Rev. Acad. Colomb. Ci. 8:40. 1950. 



COLOMBIA: Valle: Puerto Merizalde, Costa del Pacifico, Rio Naya; bosques; alt. 5-10 

 m; Cuatrecasas 14025 (type, NY, US). San Isidro, Rio Cajambre; Cuatrecasas 17289 (para- 

 type, F, NY, US). 



The type colleetion represents immature flowering male material. The 

 larger number of sepals (9-10) of the flower buds seems to represent a distinct 

 departure from the prevailing number in the sect. Omphalanthera (usually 6). 

 The fruiting specimens of the paratype indicate close relationship with C. 

 brachystyla of Venezuela, and perhaps with the poorly known C. eugenioides of 

 Colombia. 



6. Clusia. eugenioides Planch. & Lind. Mem. Guttif . Ann. Sci. Nat. ser 4. Bot. 



13:328. 1860 



Known certainly only by the type collection, Schlim 934, from 4000 ft alt., Santa Marta 

 (holotype P, isotypes Herb. Boissier G, Herb. Delessert G). 



Three other collections have tentatively been assigned to C. eugenioides, viz., Dolores, 

 Tolima, Colombia, 1300-1700 m, Lehmann 7302 (K 3 sheets, US) ; climbing shrub, flowers 

 showy, white, with slight rose flush, on fallen tree, at 750 m alt., Quebrada Bruno, Comisaria 

 Goajira, Colombia, 26 Aug 1944, H aught 4329 (NY, US) ; tree 60-80 ft. high, flowers dark 

 pink, thick forest at bank-side, El Umbo region, Mt. Chapon, extreme western part of Dep. 

 Boyaca, northwest of Bogota, Colombia, 25 Sep 1932, Lawrance 473 (NY). 



The four collections cited here bear some similarity in general facies. Col- 

 lectors' notes indicate considerable differences in habit. Geographical disposition 

 of the four collections raises further question of their conspecificity. Not im- 

 probably a species-complex is represented among even these few specimens. 

 Until considerably more material is at hand, any specific delimitation within the 

 complex is impractical.
