the Clova district (Rev. J. Fergusson) ; Glas Mheal, Perth- 

 shire, at an elevation of 2500 feet (Gr. E. Hunt) . 



In the latter station it was accompanied by Thuidiwn 

 decipiens } De Not.; Bryum Duvalii, Splachnum vasculosum, 

 and other rare species. 



The allies of Philonotis adpressa may be distinguished 

 from it as follows : — 



Philonotis calcarea has longer, secund, very acute leaves, 

 with areolae twice or thrice as large, oblong ; basal areolae 

 larger, elongate-hexagonal. 



Philonotis fontana has leaves usually spreading, but 

 sometimes secund, longer, suddenly acuminated halfway 

 up, very acute, very distinctly plicate, margin strongly 

 recurved ; nerve much thinner ; areolae linear above, 

 small and oblong towards the base of the leaf. 



Philonotis seriata, Mitt., has leaves with a distinctly 

 spiral arrangement, from a suberect base, patent towards 

 the apex, ovate, acute, plicate, margin distinctly reflexed ; 

 areolae linear above, small and ovoid towards the base of 

 the leaf; perigonial leaves from an erect dilated base, 

 which is composed of rather large linear cells with a red 

 tinge, upper part of leaf widely spreading, cordate-trian- 

 gular, obtuse; areolae elongate-quadrangular, very small 

 and obscure; nerve thick and indistinct, continuous or 

 vanishing below the apex; margin slightly denticulate. 

 This species was first described in Mitten's " Musci Indiae 

 Orientalis," in the ' Proceedings of the Linnean Society ' 

 for 1859. ^ * s frequent in springs at the head of Clova, 

 fruiting freely in favourable seasons. 



Thuidium decipiens, De Not. [Hypnum rigidulum, Ferg.,

 gusson in ( Science Gossip/ and noticed in the ' Journal
