A praecedentibus foliis longioribus primo aspectu discrepat, 

 caeterum imprimis tuberibus edulibus excellit. F. v. Mueller 

 dicit 1. c. : « This species is by its tubers already distinguished 

 from ail others, except Tr. deflexa and Tr. cirrosa, but syste- 

 matically it ought to be placed near Tr. effusa, from which the 

 longer, narrower and laxer leaves, as well as the evidently larger 

 fruits, already distinguish it. »
