3 to 5-parted, with distinct partial petioles. Stem difTusely branched, the 

 flowers small, partly funnel-form, disposed in cymose racemes. Capsule oval, 

 the cells 2-seeded; the seeds roundish, not angular. Closely allied to Col-

 lous ; leaves alternate, digitately united at the base; leaflets 3 to 5, lanceolate 

 acute, attenuated into a petiole, two or four much smaller than the others;
