Species primo intuitu calcare apice circinato, et capsula brevi oligo- 

 sperma valde distincta, sed foliis variabilis. Caulis pedalis. Folia 

 interdum late elliptica grosse crenata subtus subglabra, petiolo i-l". 

 Pedunculi foliis longiores. Racemus regularis, floribus nempe sub- 

 aiquidistantibus, bracteisque omnibus consimilibus. Pedicelli vix V, 

 patuli. Flores membranacei. Capsula brevis, ^" longa, compressa, 

 elliptica, utrinque acuminata, oligosperma. Semina 2, orbicularia, 

 eompressa, nitida. 

 The habit of this is that of I. uncinata, subcordata, and others of the 



umbellate section, but the inflorescence is decidedly racemose.
