FLORA OF BRAZIL. 91 
Folia disticha, glauca, enervia. Seta brevis. Capsula pallida, 
erecta. Florescentia monoica. 
Aulacopilum glaucum. 
Has. New Zealand, on trees, growing intermixed with Mabronia 
secunda. 1843. Rev. W. Colenso. 
Very small, scarcely larger than the Fabronia. Stems creeping, 
sparingly and irregularly branched. Leaves distichous, obliquely 
ovate, acuminate, spreading, flattish, nerveless, papillose at the 
margin and on the back, areolæ granular, colour glaucous-green ; 
when dry appressed. Perichætial leaves erect, lanceolate. Seta 
not twice the length of the capsule, pale and rather thick. Cap- 
sule roundish-ovate, pale glaucous-green, truncate. Operculum coni- 
co-rostellate, about half the length of the capsule. Calyptra large, 
nearly twice as long as the capsule, closely embracing the seta 
below it, and in other respects like that of CaZymperes, at length 
split laterally, with a tendency to separate at the base into eight or 
more laciniæ corresponding with the number of furrows, pale yel- 
lowish-brown, reddish at the apex. Spores green, rather large. 
Perigonii orange-coloured, anthers without paraphyse. 
The singular calyptra, the absence of peristome, and indeed the 
whole habit of the plant, entitle it to rank as a new genus, bearing 
almost the same relation to other Pleurocarpi that Calymperes does 
to the Acrocarpi. 
This very curious moss may perhaps form the type of a new 
genus. It differs from other species of Splachnum in the peristome, —— 
which is not reflexed when dry, and probably in the dioicous in- 
florescence. The habit of the moss, apart from its singular —— 
apophysis, is that of Orthodox, with which it agrees, especially in 
the structure of the peristome, and in its place of growth upon the —— 
trunks of trees. : ee
