48 NEW SPECIES OF MUSCI. 



Two inches high, pale olive. Leaves with a diaphanous, 

 subserrulate, crisped or closely-waved point. Peristome of 

 sixteen filiform, short teeth, split to their bases. Calyptra 

 mitreeform. Pericheetia axillary, hence the capsule scarcely 

 overtops the shoots. It is nearly allied to the european 

 T. fasciculare, Schrad., but the elongated linear capsules and 

 waved hair-points to the leaves, as well as the pericheetia, are 

 very distinctive. 



Didymodon, Hedw. 



1. D. luteus ; caule laxe csespitoso, elongato, subramoso, 

 ramis erectis; foliis laxe imbricatis, squarroso-recurvis, 

 canaliculars, oblongo-lanceolatis, serrulatis, margine re- 

 flexis atque flexuosis, subundulatis ; capsula ineequali, 

 cylindracea, erecta ; operculo breviter rostrato. — Common 

 on Pichincha, near Quito, Prof. William Jameson. (Dr. 

 Greville^s Herbarium.) 



Tufts loose, palet awney above, brownish below, 3 to 4 

 inches high. Texture of the leaves dense ; their nerve dia- 

 phanous by transmitted light. Peristome of sixteen linear 

 teeth, split to their bases. Setae terminal, scarcely I inch 

 long. The leaves and stems are like those of Bryum? recur- 

 vifolium, lately found in Ireland, whose fructification, hitherto 

 undiscovered, may prove to be analogous.
