• 



A species diagnosed from all the other members of the StroUHna group by its short drooping or 

 nodding spikes and its slender stems. Its nearest ally is G. Wallichii, from which it differs in leaves 

 and bracts, but with which it quite agrees in calyx, corolla, and nutlets. The Kendat specimens 

 closely resemble Cachar specimens of G. melissifolium in habit, having slender sprawling stems 6 — 9 

 I'eet in length which root at the nodes when they rest on the ground, but do not require to do so 

 if they climb over adjacent bushes.
