ON THE NEW SPECIES OF MUSCI. 453 



Leskea imponderosa, is Cryphcea helictophylla (Montagne in 

 Ann. Sc. Nat. Aug, 1845), which may be only a variety of 

 Neckera fuscescens (Hooker). — Another Moss, sent by Pro- 

 fessor Jameson, but unfortunately not in fruit, is remarkable 

 for a far more slender habit than L. imponderosa.* 



Hypnum Jamesoni, may be a new species; it is H. asperum, 

 (Hook. MSS. in Herb). 



Hypnum Drummondii, is Leskea homomalla, (Hampe, Ic. 

 Muse. t. 6). The peristome, however, is certainly that of 

 Hypnum. There is not any annulus in this species. 



Hypnum lepturum, is probably a Leskea, foliis subsecundis 

 integerrimis nitentibus basi laxe reticulatis vix ac ne vix mar- 

 gine reflexis. 



Hypnum microcladum, (Leskea ?) The capsule of one speci- 

 men is quite erect j no apophysis is apparent, nor any reflexed 

 margin to the leaf. It is nearly allied to Hypnum hyalinum 

 (Schwaegr.), which may also be a Leskea. 



Hypnum expansum, not different from Neckera longirostris 

 (Hooker), which is believed to be a Leskea, to which genus 

 other Mosses, described as Neckera in Musci Exotici, should 

 also be referred. The smaller specimen in Herb. Grevill. is 

 apparently different, and much resembles H. neckeroides, 

 (Hooker), but has a shorter nerve. 



Hypnum scariosum, may be only a variety of H. Megapoli- 

 tanum. The principal difference is in the slightly-reflexed 

 margin, and more filmy texture of the leaf. 



Hypnum solutum, is H. toxarion (Schwaegr.), according to 



* Cryphcea ? tenuissima (Hook, et Wils.), caule pendulo capillari flexuoso 

 elongato ramoso, ramis patentibus filiformibus subsimplicibus, foliis dis- 

 tantibus erectis ovato-acuminatis serrulatis seminerviis, perichaetialibus 

 quadruplo longioribus attenuatis.— (Tab. XV. E.) 



Woods, Baiios, Jameson. 



The stems of tbis exceedingly delicate Moss are a foot long and more, 

 not thicker than a hair, thinly covered with very small scattered leaves, 

 disposed in -j. The perichsetia are very conspicuous. The remains of an 

 °ld capsule, which may have belonged to this Moss, showed a Xeckeroid 

 peristome.
