of nerves on the midlobe, cross-nervules slender ; petiole 12 in., stout, soft, terete, 

 swollen at the fleshy base which is much contracted when dry ; stipules on the stem 

 free, 1 in. long, lanceolate, acuminate, reflexed, and with the margins recurved. 

 Captules shortly pedicelled, forming a head 1 in. diam., at the end of a very stout 

 smooth axillary peduncle 1-1 \ in. long; each capsule \ in. diam., very obscurely 

 tubercled and with 2 glandular patches on each carpel ; styles persistent, in. long, 

 pericarp very thin. Seeds subglobose, compressed laterally towards the hilum, pale 

 brown, opaque, nearly smooth ; testa thin, crustaceous. A very remarkable species.
