39 2 HYPNACE.^. 



Hab. Damp clefts of rocks on mountains, rare ; Scotland; Wales. Fruit very 

 rare, summer. 



A very beautiful species when growing in favourable conditions, forming large 

 deep tufts of a rich vinous red, with robust stems and large leaves, bearing more 

 resemblance, perhaps, to Camptotheciiim nitens than to any other plant ; that species 

 is however known at once by the nerved leaves and by the paludal habitat. The 

 present is a much more robust plant than the next species, though the larger forms of 

 that approach very nearly to the most slender forms of this, but the leaves are always 

 narrower and almost or quite destitute of plicae. 



2. Orthothecium intricatum B. & S. (Leskea intricata 

 Hartm. ; Stereodon subrufus Lindb.) (Tab. LI. K.) 



Much more slender, secondary stems ascending, arcuate, with 

 a few branches ; yellowish green or reddish, in silky, intricate 

 tufts, i-i| inches high ; leaves very glossy, almost always secund 

 and homomallous ; resembling those of the last in shape, but 

 much smaller, \-\ line long, and not plicate; margin plane; 

 nerve none or obsolete, areolation as in O. rufescens. Seta 

 short, about f-inch, capsule small, oval-oblong. 



Var. /3. binervulum Husnot (O. binervulum Mol.). Leaves 

 wider, ovate, less longly acuminate, sub-plicate. 



Hab. Damp subalpine rocks, not common. Fruit summer, not found in 

 Britain. 



This species somewhat resembles Hypnum cupressiforme var. resupinalum, but 

 is of a more reddish colour, less branched, with the leaves more longly acuminate, and 

 no distinct angular cells ; and is moreover a rock plant ; the same characters will 

 separate it from Pylaisia polyantha. 



Husnot mentions the var. $ as being found in Scotland, but I have seen no other 

 record, nor have I seen specimens. His figure, however, would seem to indicate that 

 it is a marked variety (Muscol. Gall. p. 317, Tab. 90). 



106. LESCUR.EA B. & S. 

 (Lesquereuxia Lindb.) 



Primary stem creeping, rooting, irregularly divided, branches 

 few, slender. Leaves lanceolate-acuminate ; nerve long, thick, 

 single, areolation shortly rhomboid. Capsule erect } oblong. 

 Peristome teeth confluent at the base ; inner without cilia and 

 with a short basal membrane. Dioicous. 



1. Lescuraea Striata B. & S. (Pterogonium striatum Schwgr.) 



(Tab. LII. A.). 



Secondary stems very slender, creeping, somewhat pinnately 

 branched above, olive green or yellowish, forming low intricate
