4.  Leaf blade underside with conspicuous secondary veins
4.  Leaf blade underside lacking noticeable secondary veins or these very obscure
5
5.  Sepal lobes lanceolate, glabrous to puberulent; apex of the uppermost anther even to protruding from the corolla throat; styles 10-19(26) mm long, united for >1/2 of length, longer than the calyx
