DisTRIBUTION: Tropics and subtropics, common. 
ILLUSTRATIONS: Hook. Sp. Fil. 1: pl. 47A, 57A. 1856. 
SPECIMENS EXAMINED: Hawaii, Robinson 253 V; 261 V; Maui, 
Baldwin B; Robinson 356 V; Oahu, Beechey C; Heller 2012 C; 
2327 C; Meyen B; Wilkes Expedition B, C; Kauai, Forbes 423 
BM; Heller 2480 C; 2803 C; Molokai, Hillebrand B; Hawaiian 
Islands, Baldwin 8 B, C; Miss Sessions C. 
The specimens vary as to the amount of pubescence, those 
collected in certain very moist localities, such as the Olao woods 
(Robinson 253 V, 261 V), being much more furfuraceous than those 
collected in drier localities, as Heller 2803. The variation from 
narrowly to broadly lanceolate is not correlated with this, nor is 
there any correspondence in size with the greater size of Microlepia 
hirta, hence Hillebrand’s variety hirta may be disregarded.
