This borders very closely upon Gymnoslomum gracile {Leplo-
slomum Rr.) already figured in this work. It is however a much
more robust plant, having larger stems, which for nearly their
whole length are covered with thick, deep-brown, ferruginous
downy radicles, having at their summit a short thick tuft of leaves,
and exhibiting in various parts of their length the terminal tufts
of former years; so that the plant increases in length by its an-
r.otinous shoots, like many of the Bartramioe. The fruitstalk
too is shorter than in G. gracile, the capsule larger and more
ovate, and the leaves are more obtuse, with shorter hairs.
The membrane which constitutes Mr. Brown’s character of
Leptostomum is here rather erect than horizontal, and the edge
jagged ; there is too a faint appearance of longitudinal lines
like the cohesion of short obtuse and irregularly-formed teeth ;
but as 1 bad only one specimen to examine, I cannot speak with
that certainty of its structure that I could wish.
