Tufts about one inch high, light green above, brownish beneath. 
Leaves scarcely amplexicaul, their nerve often indistinct, always 
filling up the acuminated parts. ^ Peristome of sixteen bifid, 
barred teeth, whose segments are alternately unequal. In Dicra- 
num suulatum, Hedw., the tufts are of a yellow colour and much 
shorter, the nerves of the leaves are distinctly defined and their 
tops are more setaceous, while the lid has a longer beak, and the 
capsule is shorter and wider. 
2. D. campylophyllum, Tayl. Caule cæspitoso ; surculis subsim- 
plicibus, erectis; foliis subdistantibus, ex oblonga arcte vagi- 
nante basi elongate subulatis, integerrimis, nervo tenui percursis, 
apice flexuoso incurvis; capsula ovata, erecta, subæquali ; 
operculo rostrato. 
On Pichincha. Prof. W. Jameson. 8th Aug., 1847. 
Tufts nearly two inches high, pale green above. The sheath of 
the leaves has its margin at the top slightly reflexed; the subu- 
late portion departs at a considerable angle from the stem, and is 
three times as long as the sheath; it is most minutely crenulate 
at the point from the projection of its cells. Capsule without any 
apophysis: teeth of the peristome sixteen, dark red, barred, 
divided half-way down into unequal /acimie. Lid scarcely as long 
as the capsule. From Dicranum vaginatum, Hook., which has 
likewise been collected by Professor Jameson on Pichincha, the 
present differs by the teeth of the peristome being far less deeply 
divided, by the more elongated points of the leaves, and by the 
shorter and more equal capsules. Dicranum Jamesoni, Tayl., is
