Derivation. From dis, twice, and ous, dtos,an ear. The calyx of the female flower ends in two 
segments, which fancy may compare to ears, although they more resemble horns: and this second 
idea is doubtless that referred to in Tournefort’s generic name Ceratdldes, from keras, a horn, 
gen. keratos, and eidos, likeness.
