Rocks above Loch Callater, Aberdeenshire. Dr. Greville. Fr. 



Some tufts of this remarkable plant have been found in the station just 

 mentioned : but destitute of fructification. In general appearance this 

 moss resembles Bryum julaceuni; even the fruit, which I possess from 

 the Tyrol, is very unlike that of any other Weissia. The capsule is more 

 or less cernuous; but this is not owing to a curvature in the base of the 

 fruit, but in the upper part of the seta. 



4. W. Starkedna, Hedvv. (Starkean Weissia); stems very short, 

 leaves ovate with an excurrent nerve, capsule ovate erect, lid 

 conical, teeth of the peristome subulate acute (mostly red).

 Teeth of the peristome connected by a common base. Wilson. 



5. W. affinis, Hook, and Taylor, (blunt-toothed Weissia); stems 

 very short, leaves ovate with an excurrent nerve, capsule ovate 

 erect, lid conical, teeth of the peristome short broad obtuse 

 whitish. Muse. Brit. ed. 1. p. 44. ed. 2. p. 79. t. 14. 



Fields and on gravelly banks. Fr. Jan. — The difference in the peri- 

 stome of this plant from the last is most striking, and resembles that 

 of W. trichodes in its more perfect state: yet in other respects it is 

 hardly to be distinguished from W. Starkeana. 



6. W. lanceoldta, Hook, and Taylor, (lance-leaved Weissia); 

 stems somewhat elongated, leaves ovate with an excurrent nerve 

 almost piliferous, capsule ovate, lid obliquely rostrate. Muse.

 — Bryum lanceolatum, Dicks. 



Moist banks. Fr. March. — Allied to the two preceding, but having 

 a rostrate lid ; and to Gymnostomum truncatulum, especially the larger 

 varieties of it ; but the leaves are more erect, more closely imbricated, 

 and the apiculus is longer. Teeth of the peristome oblique, as in W. verti- 

 cillata, separate to the base, sometimes split, as in Didymodon. ( Wilson.) 



7. W. latifolia, Schwaegr. (broad-leaved Weissia); stems un- 

 branched very short, leaves broadly obovate with a small acu- 

 men concave imbricated shining, the nerve reaching nearly to 

 the point, capsule oblong cylindrical erect, lid rostrate. Schivaegr.
