Hallier in Baum's Kunene-Sauibesi Expert. 346, cites Baum's plant as "I. hie- 

 pharophylla, Hallier f., var. cordata, Rendle=7. porrecta, Rendle and Britten"; 

 it is therefore doubtful whether the number should be included here or under I. 

 llepharophylla. The two species are quite distinct, the several-flowered almost 

 capitate inflorescence at the end of the long peduncle, being characteristic of I. 

 porrecta.
