ORTMOTRICIiUM LONGIROSTRUM.
Orthotrichum caule repente, ramis erectis, foliis lanceo-
Into-acuminatis striatis siccitate tortis, seta longa,
capsula ovali-elliptica sulcata, calyptra glabra multi-
ficla, ciliis nullis, dentibus 16 vix per paria approxi-
matis. (Tab. XXV.)
H a b . In sinu Dusky Bay dicto, in Nova Zeelandia. D. Men zies,
1791.
Caulis repens, ramosus, ramis erectis, simpiicibus vel divisis. Fo-
ha^ aureo-lutescentia, nitoris expertia, undique denseque imbricata,
erecto-patentia, siccitate torta, lanceolata, acuminata,
integerrima, longitudinaliter plicata, sub lente punctata. Fe-
rkhætiaUa reliquis similia, sed plicis nullis. Setoe numerosæ,
semiunciam loiigæ, erectae, flexuosæ, flavescentes. Capsula
ovato-elliptica, siccitate præcipue longitudinaliter sulcata, rufo-
fusca. Operculum subulatum, capsula subæque longum. Ca-
hjplra^ badia, striata, glabra, mitriformis, a basi usque ad medium
in lacinias longas tenues fissa. Peristomium simplex,
16-dentatuiii, dentibus vix per paria approximatis, madore
erectis vel declinatis, siccitate reflexis, .sordide flavis, transver-
siin striatis, linea media longitudinali notatis.
th i s is another species with the same habit as that figured at
T a b . XXIV,, and with the same remarkable calyptra. A similar
calyptra Mohr has attributed to a moss which he says is nearly
related to Anictangium cirrosum of Hedwig, and to another from
Oronoko; but in both these, which he has included in his genus
Viola, there is an inner fringe exactly as in Neckera. The present
plant differs from 0 . longipes in the lengthened narrow leavK
the shorter fruitstalks, and distinctly sulcated capsules.
