pinnately branched. The branches very flat, 4 to 5 lines long, and 

 lh to 2 lines broad, obtuse, crowded, usually simple. Leaves bright 

 green, shining, rather loose, bifarious, the lateral patent-divergent, the 

 anterior and posterior appressed, all oblong acuminate, with their 

 points slightly recurved, and more or less undulate; serrulate, con- 

 cave, substriate, narrowly reflexed in the margins, furnished at the 

 base with two very short parallel costse ; areolation rather loose, of 

 linear pellucid cellules, which are here and there minutely papillose. 

 Perichsetial leaves numerous, connivent, all strongly serrate, not papil- 

 lose on the back ; the upper ones w r ith their points entire, or cut into 

 two or three segments. Capsule oblong or elliptical, hypnoid, erecto- 

 cernuous, gradually tapering into a moderately long pedicel tubercu- 

 late on its upper half only, and arising from the branches a little below 

 their base. Peristome, operculum, and calyptra, as in Holo. rugifo- 

 liurn. 



The regular pinnate ramification, the shorter, broader, and more 

 complanate branches, and the frequently dissected points of the peri- 

 chsetial leaves, readily separate this from the next species. Hookeria 

 Pliilippiensis has dissected perichsetial leaves also; but the branches 

 are terete.
