62 MR. W. MITTEN ON THE AfUSCI AND HEPATIC M % 



Weissia (Hymenostylium) calcarea, Nees et Hornsch. 

 Barren stems scattered amongst Hrywm megalacrion. 



Macromitrium acutirameum, Mitt. 



Caulis repens ramis brevibus ramosis in csespitem depressum congestis. 

 Folia ramea patentia siccitate in spiram contorta ad ramorum apices 

 in cuspidem aeutam torta, lanceolata apicem versus latiuscula et in 

 apiculum acuminata, nervo in plica carinseformi sepulta sub apice 

 evanescente, margine a basi usque ad fohi medium anguste reflexa 

 integerrima cellulis superioribus minutis rotundatis inter se distinctis, 

 basin versus oblongis parvis limitibus latis areolata. 



Caulis ubique ramis semiuncialibus cum foliis densis crassitudine circiter 

 lineam metientibus obtectus. Folia juniora viridia mox fuscescentia 

 lineam longa. 



Bartramia (Philonotis) capillata, Mitt. 



Dioica. Caulis humilis. Folia plumosa erecto-patentia a basi sublan- 

 ceolata sensim angustissime attenuata, nervo dorso denticulis scabro 

 excurrente earinata, margine serrulata, cellulis parvis oblongis areo- 

 lata; perichietialia ovato-lanceolata tenuiacuminata. Theca in pe- 

 dunculo elongato rubro globosa obliqua plicata, peristomii dentibus 

 externis internisque rubris. Flos masculus gemmifonnis foliis a basi 

 erecta dilatata vaginante crocea sensim angustatis patulis, nervo debi- 

 liore haud excurrente, cellulis longioribus areolatis. 



On wet sandy earth. 



Caulis unciam brevior cum foliis lineam angustior. Folia lineam longa 

 viridia stramineaque obscura, perigonialia minus obscura. Pedunculus 

 unciam altus. Theca, unica visa, satis magna ore parvo. 



B. (Plagiomela) radicosa, Mitt. 



Caulis elongatus radicellis rufis. Folia a basi erecta obovato-oblonga, 



cellulis angustis hyalinis areolata, subito longe subulato-angustata 



patentia, margine argute serrulata, cellulis parvis angustis nervoque 



ubique papillis obscura. 

 Growing in loose tufts in coarse sand. 

 Caulis biuncialis. Folia 3-linearia, superiora aeruginoso-viridia sub- 



glauca, inferiora fusca, omnia in acumen crassiusculum nee capillare 



attenuata. 



Like B. vulcanica ; but in that the leaves are attenuated into 

 long hair-like points. B. commutata, Mitt., differs also in the same 

 particular. 



B. inconspicua, Mitt. 



Humilis. Folia erecto-patentia patentiaque lanceolata sensim augustata, 

 nervo scabro percursa, margine argute serrulata inferne vix reeurva,
