OF THE FORTY-NINTH PARALLEL OF LATITUDE. 47 
ferous Hedwigie and Leucodon sciuroides, which produces flagella 
of exactly the same kind as those of H. (Braunia) sciuroides. In 
Cryphea there are several species which closely resemble H. 
ciliata and H. imberbis, having their fruit terminal on their 
branches, and immersed in a similar manner. There is also a 
great resemblance between the more branched Hedwigie and 
Antitrichia curtipendula, Brid., which also produces the same kind 
of flagella, and is in reality itself only a Leucodon with a more 
completely developed peristome, and improperly separated from 
that genus. 
Since the foregoing description of this moss was written, there 
has appeared, in the Transactions of the American Philosophical 
Society, Mr. Lesquereux’s description of Braunia Californica, which, 
in so far as can be generally gathered from the description, would 
appear to indicate the same species. On consideration, however, 
as there are some discrepancies, it has been thought best to let the 
description of H. pilifera stand, and to point out the differences 
which exist between Dr. Lyall’s specimens and Mr. Lesquereux’s 
description. They are, in our specimens, the stems not * vel 
simplicibus vel irregulariter innovando ramosis," nor “apice 
incrassatis duris;"' the perichetial leaves not “ brevioribus," but 
elongated, and the capsule plicate—in fact it is just the cap- 
sule of H. imberbis on an elongated pedicel. Mr. Lesquereux 
says that his species has a capsule “exactly top-shaped" when 
deoperculate, but nothing about the plication so evident in our 
specimens. 
ANTITRICHIA, Brid. 
A. CURTIPENDULA, Linn. 
Hab. Vancouver Island, Wood; British Columbia, Lyall and Douglas. 
Very different in external appearance from the usual European 
states; but there seems to be no sufficient distinction between 
these specimens and the form which has a more slender habit 
and elongate capsules, enumerated by Schimper as var. ß. His- 
panica. Some of the specimens are very slender.
