the origin of the peduncle, twice trifid, and each primary 
branch much longer than the space below to the origin of 
the peduncle, each ultimate division supporting three cor- 
date, acuminate leaflets, of which the lateral ones are 
oblique, the central equal, glabrous above, hairy below, 
three to five-nerved, reticulate. Peduncles of unequal 
length, solitary, arising (about an inch and a half) below 
the primary division of the petiole, and sometimes as long 
as the leat, generally shorter, round, glabrous. Flowers 
violet-coloured, large and handsome, subtended by several 
unequal, deciduous bracteas, racemose on the upper half of 
the peduncle, cernuous; the lower pedicels occasionally 
subdivided, the others simple. Sepals four, ovato-lanceo- 
late, acute, spreading wide, undulate. Petals imbricated, 
rounded, erect, cucullate, inflected in the edge, each with 
a subulate ascending spur rather longer than the petal. 
Stamens erect, shorter than the limb of the petals ; filaments
