It is interesting to note that on page 751, Brotherus says that this is un- 
doubtedly a distinct genus, but he failed to name it, or to adopt its oldest 
specific name. It has been collected at five stations in Florida, and is found 
in the West Indies and in the northern part of South America. 
This species has also been collected by Mr. R. S. Williams in Bolivia, and 
was referred to Acrocryphcea , from which it differs in the elongated cells of 
the upper part of the leaves and the much more prominent basal differentia- 
tion of the cells.

This is the way that Brotherus disposes of Macouniella. Cardot has 
called my attention to the fact that A. Calif ornica var. flagellifera. E. G. 
Britt. Bull. T. B. C. 32:266.1905, is unknown to him. It is evidently a mis- 
take for Alsia Calif ornica flagellifera R. & C.

mersa (Sull ) Lindb., F. Ohioensis (Sull. ) Lindb., and F Floridana (Lindb.) 
Kindb. are listed and Cryfhcea Ravenellii (p. 742) is omitted, as it 
should be.

A. Calif ornica, and the variety flagellifera R. & C., are listed. Alsia 
longipes Sull is said to be a Thamnium. This species has recently been 
included in the following genus by me. (Bull. T. B. C. 3 2:265.1905.) 
Dendroalsia E. G. Britton Bull. T. B. C. 32:263. May, 1905 
Groutia Brotherus E. & P. Plfanzenfam. Lief. 223 . 760. Aug., 1905, 
D. abietina (Hook.) E. G. Britt, and D. circinnata (Sull.) E. G. Britt, 
have been included in Alsia Sull. & Groutia Broth ; they seem to me to be 
sufficiently distinct and to include Alsia Macounii Kindb. 
These specimens from Lake Pond d’Oreille, Idaho, collected by J. B. 
Leiberg, are the finest that have ever been collected of this species. The 
accompanying photograph (Plate II) shows the size on the herbarium sheet 
on which they are mounted. 
Eucladium verticillatum (L. ) Br. & Sch. on rocks in a spring near the 
Holston River, at Marion, Va. June 6, 1892. This moss has only been re- 
corded from the Western States, California. It occurs also in Bermuda.
