B. Leaves squarrose. 



H. cuspidatum ; leaves loosely set, ovate, concave, nerve- 

 less, entire, the lower ones squarrose, those at the summit 

 closely imbricated into a cuspidate point ; capsule oblong, 

 curved, cernuous; lid conical. (TAB. XXVI.)

The habit of this plant is very similar to that of H. cor- 

 difblium, a dark variety of which Mr. Turner has made his 

 var. /3. The present plant is easily known by the sharp cus- 

 pidate extremities. 



H. cordifolium ; leaves loosely set, squarrose, cordato-ovate, 

 obtuse, concave, entire, their nerve running very nearly to 

 the point ; capsule oblong, curved, cernuous ; lid conical,

HAB. Bogs, 



' A purple variety of this plant, generally barren, is found 

 in alpine situations, frequently assuming a fasciculated ap- 

 pearance, with the tops of the branches having the leaves 

 convolute ; and if the nerve of the leaf be not accurately 

 observed it may be taken for H. cuspidatum. It is accord- 

 ingly the var. /3. of that plant in the Muse. Hib, 



H. poly morp hum ; leaves loosely set, squarrose, cordate, 

 much acuminated, entire, nerve disappearing half way up; 

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

Without authentic specimens we cannot feel ourselves 

 competent to decide whether Mohr's H. chrysophyllum be 

 or be not our plant ; though if we were to judge from his 

 description we could have but little doubt of their identity. 

 Specimens sent by Mohr, probably through a mistake, under 

 the last-mentioned name, belong truly to H. stellatum. He 

 has himself cautioned us that the two plants ' only differ by 

 the presence or absence of the nerve. We have compared 

 specimens of Hedwig's H, polymorphum, and find them to
