575 
globose-campanulate, furrowed or angled lengthwise along the region of 
the stamen attachment; lobes triangular or sometimes lanceolate, acute to 
acuminate, spreading or reflexed, shorter than the tube, with the tips some- 
times inflexed ; stamens shorter than the lobes of the corolla, the oval anthers 
about equal to the slender filaments, or the filaments somewhat subulate 
and shorter; scales shorter than the corolla tube or reaching the stamens 
in some specimens, bridged slightly below the middle, fringed with medium- 
length processes; stigmas comparatively large, slender styles much longer 
than the globose ovary. Capsule circumscissile, globose, slightly depressed, 
carrying the withered corolla about it; seeds roundish, compressed, about 
I mm. long, hilum short, perpendicular. 
Type locality: "Hab. in Brasilia apud Illheos." Distribution: Vene- 
zuela, Brazil, and Bolivia, and sparingly in the islands off the coast. 
Specimens examined: Bolivia: (WeddeW J48J, j6ii). 
Brazil: (Blanchet 3047, taken to represent the type, a fragment in the Engelmann 
herbarium); Parana, Paranagua (Gardner 2684); Prov. Piauhy (Gardner 268c)); Matto 
Grosso, Cuyaba (Riedel 846 in part, mixed with C. racemosa miniata; Hoehne 4483; Lind- 
man A3 481); Sao Luiz de Caceres (Hoehne 1048).

Only specimens of the typical variety have been examined from South 
America. Engelmann segregated his variety desertorum on a specimen 
collected by Martins and named C. desertorum by him in his herbarium. 
His segregation was based on this specimen's having more rudimentary 
scales than the other varieties. In examining the type specimen I found 
that the scales were fully developed in the flower examined, and am con- 
sidering this variety the same as the typical variety. 
Specimens examined: Brazil: Prov. Ceara (Gardner 2425) ; Prov. Piauhy (Martius, 
the type of C. desertorum, a fragment in the Engelmann herbarium). 
British Guiana: (Jenman ^50^5') ; Georgetown (Rodway; Hitchcock j(55(54).
