 HAB. Moist banks and grassy pastures, especially near the 



sea. 



Very nearly allied to G. truncatulum ; but generally of much 

 larger and stronger growth, the leaves more rigid, narrow, and 

 serrated at the extremity. We can perceive no difference 

 whatever between the G. obtusum and G. Heimii of Hedwig, 

 and have hence retained the latter as the older name. 

 Schwaegrichen's G. intermedium we have referred to the present 

 plant rather than to G. truncatulum^ in consequence of the 

 serrated, or denticulated leaves. 



10. G. conicum; leaves oblongo-ovate apiculate, capsule more 

 or less ovate, lid conical. (TAB. VII.)

HAB. Fields near Cork. Mr. Drummond. Too frequent 



in the Botanic Garden, Dublin. J. T. Mackay, Esq. 

 Having recently seen this plant growing about Cork in con- 

 siderable plenty, along with Phascum rectum, and observing the 

 differences in the form of the capsule to be found among them, 

 we confess ourselves unable to discover any mark of distinction 

 between it and G. minutulum. It is among the most minute 

 of the genus, and by this particular, as well as from the very dif- 

 ferent form of the lid, it may be always known from G. trun- 

 catidum. 



Without viewing carefully the mouth of the capsule, this moss 

 may be mistaken for small plants of Weissia Starkeana.
