TORTULA RECURVATA. 
Tortula caule subnullo, foliis erecto-patentibus lanceo- 
latis acutis marginibus superne recurvis, nervo crasso 
in mucronem brevem excurrente, seta elongata, cap- 
sula cylindracea, operculo breviusculo conico-cylindra- 
ceo. (Tas. CXXX.) 
Has. In territorio coloniali Capitis Bonz Spei, in regione Rog- 
geveld, inter Jakhals Fonteyn et Kuylenberg :—terrestris, in 
campis aridis, rara. D. Burchell, 
Caules laxe cespitosi, brevissimi, simplices. Folia pallide viri- 
dia, inferiora fuscescentia, erecto-patentia, lanceolata, peri- 
chetialia lineari-lanceolata, carinata, acuta, margine supe- 
riore recurvo, nervo crasso in mucronem brevem excurrente in- 
structa. Seta sesquiuncialis, gracilis, flavo-rufescens. Cap- 
sula longa, cylindracea, rufo-fusca. Operculum breviusculum, 
conico-cylindraceum, obtusum. Peristomium pallide rufes- 
cens, 
In this species the margins of the leaves are strikingly re- 
curved, but not revolute asin T. pilifera (Musc. Exot, Tas. 
XII.) and in the European T. revoluta, nor are the stems elongated 
and branched. Some of the specimens of Barlula obtusifolia 
(Schwaegr.) are indeed described as having the stems nearly 
as short as in the present plant, and the leaves bearing the ap- 
pearance 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.
