This species is related to C. dactylophora, showing a very similar disk. 

 However, there are some differences in the flowers, such as the greater length 

 of the pistil, the fact that the stamens are not strictly included, and the slight 

 hairiness inside the calyx. They differ also in their habit, which in this new spe- 

 cies is a very characteristic one with long, conspicuous inflorescences, as well 

 as in the very scanty pubescence on the leaves and the calyx. 



The name, derived from the Greek, refers to the long, many-flowered inflores- 

 cences.
