In 1887 Dr Carrington and I. published a list of Hepaticæ col- 
lected in New South Wales by Thomas Whitelegge (2), one the 
species enumerated and figured was Lejeunea mimosa Tavl.

= I sent Dr Spruce specimens of Mr Whitelegge's collection, but 
_ heard nothing from him with reference to this species, but he 
must have had some communication with Stephani regarding it, 
for Stephani in describing it (3) says « Lejeunea mimosa Tayÿl. 
according to Spruce is dioicous » whereas Whitelegge's specimens 
are MONnoicous. i- jo

he had probably seen! a stem with only the male flowers on it, 
but in the packet there are monoicous stems, as often happens 
with monoicous species stems with only maleflowers are sometimes 
to be met with. |

be placed as a synonym of Lejeunea mimosa Tayl. Fe 
I have some hesitation as to what genus to refer Mr Weymouth's 
_ species, it differs in its yellowish-green to reddish-brown colour,

rarely acute, not usually acute, more horizontally inserted and 
Concave, not S0 twisted, smooth ceuticle not verruculose, bracts 
obtuse not acule, perianths more piriform and frontally compres-
