Scientific Name:Cardenasia
Description:Species Description - Calyx-tube extremely short, turbinate, the limb campanulate, inflated before flowering, costate, 5-toothed, the teeth very small and two of them nearly obsolete, imbricate, five of the ribs extended into setaceous awns, alternating with the teeth, the awns free before as well as after flowering. After flowering, the mouth of the calyx somewhat contracted, but the limb more or less deeply 2-cleft. Petals subequal, unguiculate, pilose. Stamens 10, irregularly subequal, all perfect, nearly distinct, free, five of the filaments slightly dilated at the base, the anthers short, oval. Stipe of the ovary short, adnate to the disk. Ovary oblong, densely pilose, several-ovuled. Style elongate, sigmoid, very thick, the stigma truncate. Fruit not known. A cirrhiferous climber, of sympodial growth, the pseudobranches opposite the leaves and terminating in simple racemes, the pedicels setaceous-bracted, the leaves 2-lobed, the stipules caducous.


Genus related to Schnella.

By those who believe in maintaining the integrity of the genus Bauhinia, as treated by Bentham and Taubert, this plant will doubtless be referred to that genus, in spite of its conspicuous long awns. I can not doubt, however, that the genus Bauhinia will in the future be resolved into a number of genera. If so, this must certainly be held distinct.
