fosum, except in having acute leaves, and which he considers to 

 be a distinct species, and the same as the 8. rugosum of Engl. 

 Bot. This we have never seen, but we fear it will prove but 

 a variety of S. vasculosum. 



Wahlenberg, indeed, says, what our own observations will 

 by no means confirm, that he has seen some states of S. vascu- 

 losum, with the apophysis of the capsule so dilated, and the 

 leaves so lengthened out, that they could with difficulty be dis- 

 tinguished from S. ampullaceum. 



7. S. Frcelichianum; leaves ovate rounded at the points, their 

 nerve disappearing below the summit, apophysis obovate 

 much narrower than the capsule. (TAB. IX.)

 HAB. On Ben High, in Aberdeenshire. Mr. Dickson. 

 We know not that any Botanist has found this Moss in 

 Britain except Mr. Dickson; and it may well be reckoned 

 among the rarest of the tribe with us. Upon the Swiss Alps it 

 is far from uncommon. 



In habit this plant is certainly very nearly allied to Splach- 

 num scabrisetum, (Hook, in Musci Exotic^ t. 32.J Systylium 

 splachnoides of Hornschuch, and Weissia splachnoides, and hence 

 Dr. Greville and Mr. Arnott have been led to unite them in 

 the genus Dissodon. 



In S. Frcelichianum the capsule is of a pale brown colour, 

 the stems scarcely ever more than half an inch in length, and 

 the fruitstalks about twice as long.
