Discovered at the foot of Mt. Roriama – Guyana during 1842 by Sir. Robert Schomberg, it was not established until 1885 when H.G. Reichenbach described and named this species after Sir. Trevor Lawrence, noted English collector during the latter half of the 19th. Century. Reichenbach based his description on specimens collected by Seidel collecting in the same region for Sander & Co. It is also to be found in Venezuela.
