leaves; capsule ovate; teeth of the peristome often bifid 

 and perforated ; lid rostrate, short. — Eng. Fl.p.l^-, Mull.

On rocks ; in Britain on those of trap formation. Arthur^s 

 Seat, Edinburgh; rocks on the coast of Fife; Fairhead, 

 CO. Antrim. Fr. April. A neat species, with elegant erect 

 capsule. As Sir AT. J. Hooker remarks, it has the leaves of 

 G.pulvinata, and the capsule of G. ovata. It is one of the 

 favourites we annually welcome in spring walks by Samson's 

 Ribs to Duddingstone village by the southern base of Ar- 

 thur's Seat, and the search for the capsules, which are by no 

 means common, adds zest to the excursion. 



A var. suhrotunda, from New Holland, has been described 

 by Mr. Wilson in 'London Journal of Botany' for 1846. 



9. Geimmia ovATA, "Web. and Mohr. [Ovate Grimmia.) 

 Stems more or less elongated; leaves lanceolato-subulate, 

 gradually produced into long diaphanous hair-like points, 

 their margins recurved; seta exserted ; capsule ovate ; teeth 

 of the peristome often perforated and split ; lid rostrate. — 

 Ikg. Fl.p. 26; Mull. Si/n. pt. 1. p. 796. 



On rocks, chiefly in mountainous districts. Fr. June. 

 This is a widely distributed and variable species, and three 

 of these varieties have been described by continental authors.
