CENSUS OF SCOTTISH HEPATIC^ 45 



I have recently revised my records for Riccia glauca, after 

 correspondence with Mons. A. Crozals, the French specialist 

 in the genus. He has been kind enough to examine several 

 boxes of living specimens from different parts of the country, 

 one of the results being that the plant which we considered 

 to be R. glauca, belongs also to R. sorocarpa. The latter 

 species has not been previously recorded from Scotland, but 

 it is evidently the more common of the two ; they are readily 

 distinguished when once known. The plant which we have 

 known as Marsupella olivacea, Spruce, will be found under 

 Gymnomitrium. In a recent important paper Studien ilber 

 kritiscJie Arten der Gattungen Gymnomitrium und Marsupella 

 in " Oester. bot. Zeit.," Prof. Schiffner shows, from an examina- 

 tion of Spruce's original specimen, that the plant is un- 

 doubtedly a Gymnomitrium, and that it is at most only a 

 variety of G. adustnm, Nees. In the same article he gives the 

 identification of Marsupella Sprucei (Limpr.), from a Moidart 

 specimen. This species is an addition to the British flora. 

 In an early number of the " Annals " I will give some notes 

 on these, also on Mars. Jorgensenii, Schffn., which is also an 

 addition to the British flora, Mars, erythrorhiza (Limpr.), 

 Loplwzia Wenzelii and LopJi. longidens. The last has not 

 been before recorded from Britain, but I am doubtful if L. 

 Wenzelii has or not ; it is not a recent discovery. Notes will 

 also be given on Taylor's Plagiocliila exigua. The plant 

 given as CcpJialoziella divaricata (Sm.), is perhaps a compound 

 species ; specimens with perianths are much required from 

 all parts of the country. It will be seen that there is no 

 vice-county number after Pallavicinia Lyellii. This species 

 has been recorded from Scotland, but I have not seen a 

 localised specimen. 



As some cryptogamic students may not be familiar with 

 the Watsonian divisions, I give them here
