so as to form a'triangular band differentiated from the median 
cells and reaching to quite a quarter and often a third of the length 
of the leaf at the margin. The cells generally, in the upper part 
of the branch leaves, are extremely short. The stem leaves are 
more finely acuminate than in 1. myurum,and the distinct recur- 
ving of the leaf margin, often extending half way up the leaf, as 
well as the upper part plane and not incurved as usual in 1. myu- 
.  rum, are also characters of some value. 
I. myosuroides differs at once in the longer alar cells, and in the 
more pointed branch leaves. is 
. The recurved margins, short cells, and somewhat stout nerve, 
together with (in the dry state) the curved branches, give the 
plant much the appearance of some forms of Eurhynch. circina- 
lum. ne 
Several North American forms come near our moss as regards 
the papillosity of the leaves, but they are all more nearly related 
to I. myosuroides and have the attenuated branch leaves of 
that species.

In two or three localities near Caldas, on rock or rocky ground 
near streams. This remarkable plant usually had the leaves 
rather large, broad and somewhat obtusely pointed; but as these 
_ characters were shared, at times, by the typical plant which grew 
in the neighbourhood, they cannot be held to be varietal charac- 
ters. The quite smooth seta in fact was the only character by 
which the variety differed from the type. à
