of Smith, of the Order Musci. 233 



We are ignorant of the calyptra of this beautiful species, but have re- 

 ferred it to this place, on account of the affinity of its habit, leaves, and 

 stipules, with those of H. rotulata and its allies.

With this species we are unacquainted. The stems, according to Hed- 

 wig's figure, are four or five inches high, and much branched at their up- 

 per extremity, in a tripinnate manner ; the leaves and stipules are desti- 

 tute of nerves.

In its general appearance this plant is liable to considerable variation ; 

 our New Zealand specimens have the branches densely fasciculated, as 

 Hedwig's figure well represents ; those from Nepaul are more loosely 

 branched, whilst in some from Jamaica the main ramifications are con- 

 siderably elongated, and the pinnae distantly placed. In our first variety, 

 the perichaetial leaves are more erect, narrower, almost plane, and of a 

 somewhat compactly membranaceous texture ; whilst both in East and 

 West Indian specimens of the variety /3, the perichetial leaves are scarce- 

 ly half so long, much more concave, and suddenly lengthened into a 

 very narrow point. Their reticulation also is considerably looser. 



We find great confusion to exist in what regards the two species of 

 this genus, which have been published by Swartz and Hedwig, under
