with rounded basal lobes, glabrous or with a sparse pubescence on both 

 sides. Cymes umbel-like, more or less elongating into short racemes as 

 the flowers develop, sublateral, pedunculate or subsessile, many^ 

 flowered; peduncles 1-4 lin. long, pubescent ; pedicels 1-4 lin. long, 

 pubescent. Sepals J-| lin. long, ovate, acute or acuminate, pubescent, 

 ciliate. Corolla 1^-2 lin. in diam., rotate or rotate-campanulate, white 

 (^Hens), glabrous ; lobes §-f lin. long, ovate or ovate-oblong, subacute. 

 Corona arising from the base of the stanfiinal-cohimn and about equal- 

 ling or slightly longer than it, about J-f lin. long, erect, cup-shaped, 

 exceedingly variable in toothing and cutting ; sometimes very shortly 

 5-toothed ; sometimes with 5 moderately long teeth of variable form, 

 entire or bifid at the apex, having 5 minute teeth alternating with 

 them ; sometimes with 10 filiform teeth in 5 pairs, each pair alterna- 

 ting with 3 minute teeth ; sometimes divided nearly to the base into 5 

 cuneately- quadrate lobes alternating with the anthers, produced at the 

 apical angles into shorter or longer teeth and entire or denticulate 

 between them ; two or more variations often occur on the same speci- 

 men ; usually, but not always, there are 2 slight keels within, opposite 

 each of the 5 principal teeth, or when the corona is divided into quad- 

 rate lobes there is a slight keel near each margin. Staminal-column 

 not exceeding the corona ; anther-appendages orbicular, inflexed over the 

 truncate or dome-shaped apex of the style. — Hiern in Cat. Afr. PI. Welw.

This is one of the most variable Asclepiads, as to its coronal structure, that I 

 have examined, and when I described C. vagum and C. hrevidens, I had no idea that 

 two such dissimilar coronas could belong to the same plant ; on subsequently received 

 specimens, however, I found both ibrms of corona and some other modifications as 

 well on the same specimen. Usually, within very slight limits of variation, the 

 corona of each species is very cons'ant in its fonn.
