A stout lofty climber. Leaves 4-8 in.; upper 2-3 in. broad, lower 3-5; broadest 

 at the cordate base, sinus deep or shallow, basal lobes sometimes incurved. Cymes 

 1-3 in., lax-fld.; peduncle and pedicels slender; bracts small, oblong. Perianth 

 2-2$ in. long, pale green ; base globose, tube curved, mouth oblique with recurved 

 margins ; lip linear, straight, obtuse, villous, as long as the tube. Capsule very 

 variable, globosely pyriform or oblong, with the long stipes l-2 in. long, mem- 

 branous. Seeds most variable, obtusely triangular in the smaller capsules, -| in. 

 broad, with narrow wings and one face studded with tubercles ; in larger capsules the 

 seeds are larger and more broadly winged and lip tubercled ; in the largest capsules 

 the seeds are in. diam., with very broad .wings, and a thin disk quite smooth or 

 sparsely tubercled on one face. The variations in the leaves of this plant are remark- 

 able, but not so much so as are those of the capsule and seeds. I long thought that 

 these indicated at least two species.
