Perthshire, at an elevation of 2,500 feet — G. E. Hunt. In 

 the letter station it was accompanied by Thuidiuin deci- 

 pieyis, De Not.; Bryum Duvalii, Splachnum vasculosuni, 

 and other rare species. 



The allies of Phiionotis adpressa may be distinguished 

 from it as follows. 



Phiionotis calcarea has longer, secund, very acute leaves, 

 with areolae twice or thrice larger, oblong, basal areoloe 

 larger, elongate-hexagonal. 



Phiionotis fontana has leaves usually spreading, but some- 

 times secund, longer, suddenly acuminated half way up, very 

 acute, very distinctly plicate, margin strongly recurved, 

 nerve mu ch thinner, areolae linear above, small and oblong 

 towards the base of the leaf 



Phiionotis 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 triangular, 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. It is frequent in springs at the 

 head of Clova, fruiting freely in favourable seasons. 



Thuidiwni decipiens, De Not.; Hypnum rigidulum, Ferg. 

 MSS. This species was lately described by the Kev. J. Fer- 

 gusson in Science Gossip, and noticed in Joiu^nal of Botany, 

 October, 1871. It had been collected in 18GG on Ben Lawers 

 by Dr. Stirton, but was for some years confounded with Hyp- 

 num commutatum, to which species it bears much resemblance. 

 The Rev. J. Fergusson, however, satisfied with its distinct- 

 ness, distributed it in 1870 as Hypnum rigiduhim, Ferg., 

 species nova ; and a few months since Juratzka identified it 

 with Thuidium decipiens, De Notaris, Briologia Italiana, 

 1869. It occurs in springs, and is found in Britain on Ben
