Monro's Mysore plant referred to li. involucrata is possibly R. Lyellii. 

 It is very unlikely to be Roxburgh's plant.

Climbing over rocks and lofty trees. Leaves B-jugate, rarely 3-jugate, the up- 

 permost only 3-foliolate, 3-7 in. long, leaflets large 125-3*25 in. long, •75-175 in. 

 ■wide, ovate or elliptic, base rounded, apex acute or mucronate, marginal teeth 

 rather small, petiolulate ; petiole glabrous minutely glandular above, margin of sti- 

 pules minutely glandular. Flowers solitary, peduncles h-lh in long. CaZt/aj-tube 

 ovoid as long as the peduncle; calyx-lobes 1'5 in. long, margins entire, lanceolate, 

 minutely spathalate at the tips, glabrous externally, finely pubescent within.

A magnificent species, very like an extremely luxuriant form of R. indica Auct. 

 but the writer believes quite distinct.
