Weissia Martiana. Hoppe et Hornsch. M S S .
H ab . In alpibus Tyrolensibus. D. Hornschuch.
Caules 3 -4-pollicares, erecti, densissime cæspitosi, subramosi
innovationibus præcipue, ferrugineo-tomentosi, apicibus solummodo
viridibus. Folia undique imbricata, horizontalité!'
patentia, pallide viridia, lanceolato-subulata, carinata, integerrima,
margine subrecurvo, nervo saturatiore instructa. Peri-
cheetiaVm reliquorum similia, sed margine non recurvo. Seta
vix bilinearis sæpe ob innovationes lateralis, pallide flavo-fusca,
insigniter curvata. Capsula recta, globosa, rufo-fusca, profunde
sulcata, sulcis viridi-fuscis. Operculum et Calyptra desunt.
Peristomium intense rubrum, dentibus 16, longiusculis, basi
latis, apice attenuatis, transversim striatis, siccitate æquç ac
madore subhorizontaliter positis intra marginem capsalte.
This singular plant, which has been found only by Professor
Hornschuch in the Tyrolian Alps, is at once distinguished from
every other species of the genus by its curved fruitstalk and the
globose and deeply sulcated capsule. Its nearest ally is W. nU
g rila : but, independently of the marks now pointed out, there is
a remarkable curvature in the capsule o£ the last-mentioned spe«
cies, whilst in G. Martiana it takes its direction from that of
the fruitstalk.
