HAB. Moist rocks. 



' Steins from two to three inches in length. Under G. cur* 

 virostruni Sir James Smith, in Fl. Brit., has given a de- 

 scription drawn from specimens so named by the Rev. H. 

 Davies, which are nothing more than G. luteolum, Engl. 

 Bot. (G. cestivum, Hedw.) But according to authentic 

 specimens, those of G. stelligerum and G. ceruginosum 

 figured in EngL Bot. are the true G. curvirostrum. 



** Stems short} simple. 



G. Griffithianum ; leaves obovato-rotundate, reticulated, their 

 nerve disappearing below the summit; fruitstalk carnose, 

 thick; lid hemispherical. (TAB. VII.)

HAB. Mountains in Wales, Yorkshire, and Scotland. 



The stems, as in all the remaining species of this genus, 

 never exceed half an inch in height. The membrane stretch- 

 ing across the mouth of the capsule, noticed under the ob- 

 servations to the Generic characters, is only to be seen in 

 fresh specimens. The seeds are large. The habit is that 

 of a Splachnum ; the leaves very cellular ; the fruitstalk re- 

 markably succulent ; the lid nearly flat ; the calyptra is 

 lanceolate, and from the few specimens we have examined 

 appears to be dimidiate. Obovate bodies are imbedded at 

 the base of some of the leaves in a clustered manner, as in 

 many of the Jungermannice, and may be considered gem- 

 mce. Sir James Smith has erred in saying that Mr. Hooker 

 found this plant on Ben Lawers in Scotland. His speci- 

 mens, which are those figured in Engl. Botany, were ga- 

 thered by the Rev. Mr. Dalton and himself on Inglebo- 

 rough, Yorkshire, The late Mr. Donn however, of Forfar, 

 communicated specimens to Mr. Lyell from mountains in 

 Angusshire. 



6. G.ovatum; leaves ovate, erect, concave, piliferous, their 

 nerve furnished with a granuliferous membrane ; lid ros- 

 trate. (TAB. VII.) 



4. vulgare j capsule ovate.
