Mr, Hooker's Descriptions of new Mosses from Nepal, 321 



I am at a loss to say which Hypnum approaches most nearly 

 to that here figured, as it belongs to the division " ramis tereti- 

 bus," the most numerous and intricate of this immense genus. 

 I flatter myself, however, with the hopes that the figure and cha- 

 racter here given will serve to distinguish it from all others. I 

 have named it after Dr. Francis Buchanan, who found all the 

 mosses that form the subject of this paper. 



Tab. XXVIII. Fig. 3. 



a. Hypnum Buchanani, natural size. 



b. part of the branch, magnified. 



c. stem leaf.

e. capsule, with the operculum.

17. Hypnum crispatulum. 



Hypnum caule adscendente, ramis erectis aduncis, foliis falcato- 

 secundis lanceolatis serratis uninervibus siccitate crispis. 



Caules adscendentes, simplices, vel bis rer dichotomi. Rami 

 erecti, apicibus incurvatis, undique foliosi. Folia dilute 

 fusco-flavescentia, nitidiuscula, undique imbricata, laxe 

 disposita, falcata, secunda, oblongo-lanceolata, acuminata, 

 ncrvo concolore infra apicem evanescente instructa, et striis 

 aliquot longitudinalibus notata ; per totum marginem ar- 

 gute serrata, plana, vel saepe concavo-carinata, paullum 

 undulata, siccitate insigniter crispata. Fructificationem non 

 vidi.
