We received from the Department of Agriculture specimens 
collected by Wolf and Rothrock in Colorado, 1873, which agree 
with the description given by Limpricht of this variety in the 
short seta, small capsule, with a small mouth, short teeth, lacking 
on some of the capsules, and the cells of the walls broader and 
much thickened, with very distinct stomata. The spores, how- 
‘ver, seem to be smooth as in the species.

We quote the original description: 
Dioica ? caule brevi ramoso, foliis patentis concavis ambitulate ellipticis acutis 
Paulo supra basin angustatis nervo percurrento obtuse carinatis, margine minute eroso, 
cellulis basi infima oblongis hyalinis inde viridibus mox abbreviatis quadrato-rotunda- 
tis papillosis, perichaetialibus parvis vaginulam vix superantibus latissime ovatis acutis 
theca in pedunculo longissimo rubro ovato-cylindracea basi apophysata, operculo subu- 
lato subaequilongo-peristomo dentibus angustis elongatis, calyptra basi nuda apice 
laevi.” 
“Seta an inch and a half long, slightly flexuose. Capsule too 
immature to show if it is furrowed.” 
Lesquereux and James, in their Manual, on page 183, say ina 
foot note: 
“Upon examination of the specimens of £. /ongipes Mitt. in all 
of Drummond’s sets the characters have been found identical with 
ose of LZ. procera; the plants monoecious ; the calyptra papil- 
lose, its borders emarginate, erose or fimbriate at base; perichae- 
tal leaves piliferous ; capsule spirally striate,etc. The differences 
that appear in the characters indicated by Mitten result from the 
Unripeness of the specimens he had for examination.” 
We were permitted by Dr. Watson to examine the type of 
this species at the time that Mitten’s types were still at Cam- 
bridge, and we have compared them with the original description 
and with the above remarks. We can corroborate Mitten’s state- 
ments, with additional evidence that this is not the same species 
as £. procera. 
The calyptra is smooth throughout, and so is the vein of the 
Narrow leaf, which, moreover, as the description says, has a
