 Anisothecium Grevillei LINDB. op. c. 26 (1878). 



Dioicous or autoicous ? densely casspitulose, glossy yellowish green ; 

 leaves from a wide sheathing base, suddenly narrowed into a flexuose- 

 patulous subula, margin subundulate, quite entire or with 2 or 3 

 irregular serratures at apex; basal cells elongated, upper oblong; 

 perich. bracts more sheathing. Capsule cernuous, on a purple seta, 

 obovate or oval, subgibbous, faintly striated, solid, exannulate, with a 

 short tumid or obsoletely strumose neck ; lid with a subulate beak. 

 Male infl. gemmiform, terminal ; bracts convolute, lanceolate-subulate. 

 HAB. Damp clay soil in mountain districts ; rare. Fr. 9.

Both Wilson and Schimper describe this moss as monoicous, but De 

 Notaris (Epilogo p. 641) as dioicous, observing that he could detect no male 

 infl. on fruiting plants, and this is also my experience both with original 

 specimens from Glen Tilt, and Finland ones from Lindberg. The latter also 

 have the lid conical and only slightly rostellate, so that it is evident this part 

 varies considerably, as it is usually subulate and decurved.
