44 MUSCI. [Hypnum. 



On stones and trees ; common. An annulus is present, which 

 Bridel denies, nor does he appear to me more correct in saying of the 

 inner peristome, " ciliis singulis interjectis," for I have found two inter- 

 posed filiform processes. A variety occurs at Turk Waterfall, and 

 at Blackwater, County of Kerry, with the leaves widely cordate, 

 acuminate. 



B. Leaves squarrose. 



40. H. cuspidatum, LINN. Leaves loosely set, of the sum- 

 mit closely imbricated into a cuspidate point ; ovate, nerveless, 

 entire ; the lower squarrose ; capsule oblong, curved, cer- 

 nuous; lid conical. Linn. sp. pi. p. 1595. Muse. Brit. ed. 2, 

 p. 178, t. 26. 



On wet banks ; not uncommon. 



41. H. cordifolium, HEDW. Leaves loosely set, squarrose, 

 cordate, much acuminated, entire, nerved more than half way 

 up ; capsule oblongo-ovate, curved, cernuous ; lid conical. 

 Hedw. St. Cr. v. 4, t. 37. Muse. Brit. ed. 2, p. ] 79, t. 26. 



In bogs ; rather rare. The purple alpine variety grows on Brandon 

 Hill. 



42. H. polymorphum, HEDW. Leaves loosely set, squarrose, 

 cordate, much acuminated, entire, nerved more than halfway 

 up ; capsule oblongo-ovate, curved, cernuous ; lid conical.

 cordate much acuminated, entire, (mostly} nerveless ; capsule 

 oblongo-ovate, curved, cernuous ; lid conical. Schreb. FL Lips,

 secund. One of the largest of the genus ; of a pale yellowish-

 minated, plane, serrated, faintly striated, 2-nerved at the base ;
