DICRANUM FLEXIFOLIUM., 
Dicranum caule subnullo, foliis longissime subulatis 
flexuosis, perichetialibus longe vaginantibus, seta me- 
diocri, capsula oblonga erecta levi absque struma, 
operculo conico-acuminato. (Tas. CXLIV.) 
Has. In Capite Bone Spei. D. Menzies, 1791. 
Radix parva, fibrosa. Caulis subnullus. Folia e lata basi con-

cava, g 5 flexuosa, integerrima, vO angusto, 
marginibus inflexis, inferiora breviora. Perichetialia longe 
vaginata, ad basin caulis circumvoluta, apice subulata, integer- 
rima, nervo obscuro, Seta vix unciam longa, flavescens. Cap- 
sula oblonga erecta intense fusca, levis. Operculum conico- 
acuminatum, fuscum, Peristomium et Calyptram nondum vidi. 
This comes perhaps nearest in general appearance to D. cris- 
pum ; but from that and all the other species which have little or _ 
no stem it differs in the perichetial leaves, which’ are remarkably 
sheathing like D. scoparium and its affinities. It is from habit 
alone I judge it to belong to this genus; for I have seen no peri- 
stome, and the operculum is singularly short and obtuse, in this 
respect approaching that of Didymodon purpureum and some 
others.
