224 LXX. RUBIACEE (HIERN). [ Cephaélis. 
Perhaps two species are here confused, but their separation is difficult ; in the type 
of C. peduncularis the calyx-lobes are not very small and are ciliate, and in C. coriacea 
the calyx-teeth are very small and quite glabrous, but intermediate forms appear to 
exist.

along the midrib, 44 by 24 in., margins flat, lateral veins about 13 or 
14 pairs, rather slender; petiole 4 in. long; stipules broad, 4 in. long,

peduncles of the general inflorescence 11-24 in. long ; involucral bracts 
of the heads ovate and lanceolate, acuminate, falling short of the

lobes acutely acuminate. Tube of the calyx-limb membranous, exceed-

calyx, salver-shaped ; throat densely bearded ; lobes horned at the back 
near the apex. Anthers exserted. Style exserted, puberulous an
