 (1893) p. 552 & V. 18, p. 114. Perennial ; stems very long, scandent 

 (only sliglitly twining), somewhat angular, slightly pubescent. Leaves 

 variable, 1^-2^ by |-2 in., oblong or elliptic or hastate, obtuse or acute, 

 apiculate, nearly glabrous above, base rounded or cordate ; nerves pro- 

 minent beneath with reticulate veins between ; petioles |-| in. long,

 umbellate cymes ; peduncles -^1| in. long ; pedicels -^-1 in. long ; bracts 

 caducous. Sepals |— L in. long, broadly elliptic, concave, glabrous or

Hallier f. includes this species in the section Xanthips (Engl. Bot. 

 Jahrb. v. 18, p. 133), in which the bands of the corolla are said to be 

 never lineate. I have not found the bands destitute of lines in any of 

 the specimens I have examined.
