. _ WEISSIA MARTIANA. 
Weissia caule densissime czespitoso elongato subramoso, 
foliis lanceolato-subulatis patentibus siccitate crispa- 
tulis, seta breviuscula curvata, capsula globosa sul- 
cata. (Tas.CIV.) 
Weissia Martiana. Hoppe et Hornsch. MSS. 
Has. In alpibus Tyrolensibus. D. Hornschuch. 
Caules 3-4-pollicares, erecti, densissime czspitosi, subramosi 
innovationibus pracipue, ferrugineo-tomentosi, apicibus so- 
lummodo viridibus. Folia undique imbricata, horizontaliter 
patentia, pallide viridia, lanceolato-subulata, carinata, integer- 
rima, margine subrecurvo, nervo saturatiore instructa. Peri- 
cheetialia reliquorum similia, sed margine non recurvo. Seta 
vix bilinearis seepe ob innovationes lateralis, pallide flavo-fusca, 
insignitér 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 aque 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- 
rita: 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. |
