17. Colo-Lejeunea parvula Aust. I have not seen. See 
Lindberg I. c. page 481. 
. Colo-Lejeunea Wrightii Gottsche: this plant, growing 
on bark of living trees, has been sent me from Louisiana, 
leg. Langlois. It was. known before from Cuba, and together 
with Ley. trifaria, L. auriculataand L. xanthocarpa, is largely 
distributed throughout tropical America. The last species is 
found also throughout Africa, where it has been found on the 
slopes of the Kilimandscharo, in the island of Fernando Po» 
opposite Cameroon and also at the Cape of Good Hope. Truly 
an extensive distribution ! 
There remain two species, which I have never seen and 
the suborder of which is not to be recognized from the de- 
scriptions; these are 
19. Lejeunea lacte-fusca Austin. 
20. Lejeunea Ravenelit Austin.
