TAXI-LEJEUNEA. 220 
Obs.—The ? branches are rarely uniflorous—very mostly they are 
repeatedly floriferous, one or two pairs only of leaves intervening between 
two consecutive flowers. This character, and the usually acute leaves, 
have induced me to place the species in Tawi-Lejewnea rather than in 
Hu-Lejeunea, to which its humble stature assimilates it.
