MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[VOL. 10 



This species is most closely related to C. spectabile Steyerm. in having the 

 glabrous outer surface of the corolla, pubescent anthers and connectives, and 

 manifest bracts of the inflorescence, but differs from that species in the shape 

 and relative proportions of length and width of the foliar appendage of the calyx. 

 The foliar appendage of the calyx in C. venezuelense has a similar shape to that 

 of C. intonsum, but that species has the lower surface of the leaf-blades minutely 

 puberulent.

This genus was originally based upon a species collected in Peru by Richard 

 Spruce in 1856 and published as C. decorticans in 1859 (Jour. Linn. Soc. 3: 200. 

 1859). Subsequently, C. leiophloea lien. (Bull. Mus. Hist. Nat. Paris 27: 367. 

 1921) was described from French Guiana, C. huberiana Ducke (Arch. Jard. Bot. 

 Rio de Janeiro 3: 257. 1922) from Brazil, C. surhwmensis Brem. (Rec. Trav. Bot. 

 Neerl. 31: 261. 1934) from Surinam, and C. erythroxylon Standi. (Publ. Field 

 Mus. Bot. 22: 48-49. 1940) from Pern. 



The extensive recent explorations in Venezuela by Maguire, Wurdack, et al. 

 have revealed the presence of the genus in Venezuela, represented by two collec- 

 tions, at least one of which is an undescribed species.
