12. G. tenue; stem scarcely any; outer leaves very short, ovato* 

 lanceolate ; inner ones lineari-lanceolate, all of them erect, 

 obtuse, with a strong nerve disappearing below the summit; 

 capsule oblong. (TAB. VII.)

This plant is remarkable for having two kinds of leaves, 

 of which the outer and lower ones are much the shortest, 

 and broadly lanceolate, whilst the inner and uppermost are 

 lineari-lanceolate ; both kinds are nearly plane, very obtuse 

 at the point. The capsule is cylindrical. 



3. G. Donnia?mm; stem very short; leaves subulate, straight; 

 capsule turbinate. (TAB. VII.)

This curious little plant comes nearer in habit to Weissia 

 calcarea than to any other moss with which we are ac- 

 quainted. 



G. micros tomum ; leaves broadly subulate, their margin in- 

 volute above, flexuose, crisped when dry ; capsule elliptical, 

 contracted at the mouth; lid subulate, incurved. (TAB.VII.)

In general habit this species is most closely allied to 

 IVieissia controversa ; so that it is probably only with cer- 

 tainty to be distinguished from it by an examination of the 

 mouth of the capsule. This is furnished with a delicate
