TORTULA RECURVATA.
Tortula caule subnullo, foliis erecto-patentibus lanceolatis
acutis marginibus superne recurvis, nervo crasso
in mucronem brevem excurrente, seta elongata, capsula
cylindracea, operculo breviusculo conico-cylindra-
ceo. (Tab . CXXX.)
Ha b . In territorio coloniali Capitis Bonæ Spei, in regione Rog-
geveld, inter Jakhals Fonteyn et Kuylenherg ;—terrestris, in
campis aridis, rara. D . Burchell.
Caules laxe cæspitosi, brevissimi, simplices. Folia pallide viridia,
inferiora fuscescentia, erecto-patentia, lanceolata, peri-
chcetiulia lineari-lanceolata, carinata, acuta, margine superiore
recurvo, nervo crasso in mucronem brevem excurrente instructa.
Seta sesquiuncialis, gracilis, flavo-rufeseens. Capsula
longa, cylindracea, rufo-fusca. Opercidum breviusculum,
conico-cylindraceum, obtusum. Peristomium pallide rufescens.
In this species the margins of the leaves are strikingly recurved,
but not revolute as in T. pilifera {Muse. E xo t. T a b .
XII.) and in the European T. reiioZti/a, nor are the stems elongated
and branched. Some of the specimens of Barlnda ohtusifolia
(Schwaegr.) are indeed described as having the stems nearly
as short as in the present plant, and the leaves bearing the appearance
of being recurved at the margins : but Schwaegrichen
assures us that the margins are in reality thickened ; moreover,
the apices are in that species very obtuse, the fruitstalk is short,
and the operculum long and subulate.
