Very common through the tropical and subtropical regions of the Old World. 



Usually recognised by the broad-elliptic leaves subobtuse at either end and the 

 funnel-shaped spathes. The leaves are usually hairy, sometimes glabrate (though in 

 that case often rufous-ciliate at the top of the leaf-sheath). Neither in this nor in 

 other species of Commelina do I find either the quantity or the colour of the hairs 

 constant. Various other species of Commelina are similarly amphicarpic. The 

 example of SchweiDfurth, 1607, at Kew, distributed as C. heccariana, Mart., is 

 C. henghalensis, Linn., with a piece of C. Petersii rm\e(\. with it. But C. heccariana 

 is described as having a yellow flower, so that it is not C. henghalensis.

This variety is also common in India. 



Schweinfurth gives many localities for this variety in Eritrea ; the numbers, how- 

 ever, he cites (so far as I have seen them) I should rather call typical C. henghalensis, 

 Linn. ; but no line can be drawn between the species and the Var. /3 hirsuta.
