Stems slender to medium. Flowers 3-4 mm. long, more or less glandular, 
membranous, on pedicels mostly shorter than the flowers, in racemose 
clusters; calyx lobes shorter than the corolla tube, triangular-ovate, acutish, 
not overlapping, sinuses more or less rounded, edges sometimes revolute; 
corolla campanulate or funnel-form, becoming globular about the developing 
capsule; lobes ovate-triangular, upright, with acute, inflexed tips, some¬ 
what shorter than the tube; anthers shorter than the lobes, filaments 
subulate, about equal to the oval anthers; scales not reaching the stamens 
(infrequently barely reaching them), oblong-ovate or triangular, fringed 
with medium processes, bridged below the middle; ovary globose, styles 
slender, about equal to the ovary. Capsule globose, with the withered 
corolla about it, not circumscissile, two- to four-seeded, seeds 1.5-2 mm. 
long, roundish, hilum oblong, perpendicular. 
Most of the writers have followed the example of Engelmann in con¬ 
sidering this a variety of C. racemosa Mart, it is undoubtedly closely 
related to that species, but it is believed that it exhibits characters that 
warrant its being segregated as a separate species. It is easily distinguished 
by its large flowers which are light-colored, and also by the rounded sinuses 
of the calyx. 
Type locality: Lyons, France, where it grew from seeds imported from 
Chile. Distribution: Chile, Paraguay, and Uruguay.
