WEISSIA MARTIANA. 
IF cissia caule densissime cespitoso elongato subramoso, 
foliis lanceolato-subulatis patentibus siccitate crispa-

cata. (Tas. CIV.) 
Weissia Martiana. Hoppe et Hornsch. MSS. 
Has. In alpibus Tyrolensibus. D. Hornschuch. 
Caules 3-4-pollicares, erecti, densissime cespitosi, subramosi 
innovationibus precipue, ferrugineo-tomentosi, apicibus s0- 
lummodo viridibus. Folia undique imbricata, horizontaliter 
patentia, pallide viridia, lanceolato-subulata, carinata, integer- 
rima, margine subrecurvo, nervo saturatiore instructa. Pert- 
chetialia reliquorum similia, sed margine non recurvo. Seta 
vix bilinearis sepe ob innovationes lateralis, pallide flavo-fuscay 
insigniter curvata. Capsula recta, globosa, rufo-fusca, profunde 
suleata, sulcis viridi-fuscis. Operculum et Calyptra desunt. 
Peristomium intense rubrum, dentibus 16, longiusculis, basi 
latis, apice attenuatis, transversim striatis, siccitate wque ac 
madore subhorizontaliter positis intra marginem capsule. 
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. ni- 
griia: but, independently of the marks now pointed out, there is 
aremarkable curvature in the capsule of the last-mentioned spe- 
cies, whilst in G. Martiana it takes its direction from that of 
the fruitstalk.
