 pubescence of the inflorescence, but readily I'ecognized hy the proaiineut subulate points of

8. C, pedunculatum, R, Br, Prod. 463. A twiner, citlier glabrous 

 or the inflorescence minutely pubescent. Leaves on rather lon^^; petioles, 

 (leeply cordate, ovate, acuminate, 1^ to 2^ in. long, usually with two small 

 accessor}' stipule-like leaves at their base on the side opposite to tlie pe- 

 rfuQcle. Cymes severaUflovvered, on peduncles often as long as the leaves or 

 even longer. Calyx-segments narrow, aciite,' about half as long as the 

 corolla. Corolla deeply divided into narrow ratlier acute lobes of 2 to 3 

 ™s. Corona shortly 20-lobed, 10 outer lobes short obtuse or denticulate 

 or some of them shortly acuminate, the 10 inner keels in pairs one on each 

 5ide of the lobes opposed to those of the corolla, more or less acuminate and 

 ^snally longer than the outer ones. Pruit not seen. — Cynoctomm peduncu-

*■ C. puberuium, F, MuelL Herb. Very near C, pednnculatmi, and 

 perhaps a variety, but it is all over softly hoary-pubescent, the flowers are 

 larger, and several of the outer lobes of the corona as well as the inner keels 

 jre produced into long subulate points as in C.floribundiim. Pollicles fusi- 

 lorm, acuminate, hard, about 4 in. long and 1 in. broad below the middle,
