* Through the kindness of Professor F. E. Weiss of the Owens College, Manches- 
ter, England, we have enjoyed the privilege of being able to examine the original 
ed. W 
material upon which the .Saz/eria limbata of Austin was fo nd, as does 
Count Solms-Laubach, who has also studied the type и (See Bull. Herb Boiss 
6: 773. 1898), that Mr. Austin’s diagnosis was drawn from two entirely distinct 
species, but we would differ from Count Solms as to the identity d the plant from which 
the first and greater part of Mr. Austin’s 22. was made and from which the 
character embodied in the specific name was derived. This we find to be the 2 thal- 
lus of the always Macs Asterella Cali белден We were assisted to this view by the 
discovery of an androecium, which apparently escaped the notice both of Mr. Austin 
d Count So The antheridia were found to be united ina definitely circumscribed 
and slightly elevated area and to have short ostiolar BES instead of being scattered 
and having slenderly subcylindrical ostiolar papillae as in Sauteria and C/evea. The

stomata were sometimes slightly thickened, but no more so than in Asterella Californtca
