Leaves on long slender petioles ; blade two to four inches long, 

 very variable in breadth and in the depth of the closed or open 

 basal sinus, deltoid-cordate or oblong-cordate or subsagittate, 

 with large rounded somewhat incurved auricles, tip obtuse or 

 acute, margins subrecurved, upper surface deep green, glabrous, 

 under softly pubescent and glaucous. Flowers solitary, axil- 

 lary, on slender curved peduncles exceeding the petioles. 

 Perianth two inches and a half long ; basal portion bladdery, 

 broadly obovoid, half to two-thirds of an inch long, pale 

 green; tubular portion nearly straight, strongly ribbed, expand- 

 ing into an obliquely recurved trumpet-shaped limb one inch in 

 diameter, hairy within, glabrous, coarsely reticulated, and pale- 

 brown externally. Lip stalked, much smaller than the mouth 

 of the perianth, suborbicular, rather arched, brown, with 

 stout reticulated green veins externally, pale-green within, 

 the distal half clothed beneath, with long filiform purple pro- 

 cesses. Anthers six, linear. Stigmas six, deltoid-subulate, 

 incurved, ochreous-yellow.— J. D. H.
