Notes
Closely allied to G. parviflorum WALL. ex BTH., but with a much smaller calyx with diminutive teeth and a much narrower corolla. The structure of the inflorescence in these two species is also different: verticillasters densely congested in G. microcalyx, peduncled, lax and often branched in G. parviflorum.
