Crown of the root shaggy, with rigid, red, curled bristles. Leaves 1-1} inches 
long, very much attenuated at base into a more or less obvious petiole, the limb 
cuneate, but varying in breadth from 2 to 6-8 lines ; the narrower forms answer to 
the description of Haworth’s C. clavifolia. Peduncle slender, 6-8 inches long, 
about half of it occupied by inflorescence. Flowers as in C, hemispherica, but 
rather smaller.

C. ungulata (Lam. Dict. 2.1 39); leaves opposite, semi-cylindrical,
