 narrowing towards the base and there auriculately cordate, cuspidate-acuminate, sub- 

 membranaceous, with revolute margins, Ught green and opake above, scabridulous or 

 adpressed pilosulous, with immersed nerves, beneath flavescent and opake, hirtulous, with 

 prominulent slender nerves, 2-5 in. long, lJ-3 in. broad, on petioles 8-15 lines long ; 

 raceme lateral, 4 in. long, sparsely hirsute, bearing many flowers, on pedicels 3 lines

 late scale ; coroUa 2^ in. long, glabrous, reddish-coloured ; tube cylindrical as far as the 

 middle, then funnel-shaped ; segments inequilateraUy oblong, subacute, dextrorsely convo- 

 lute, marked near the base and within the tube with many interrupted yellow lines ;
