224 The Scottish Naturalist. 



which feeds on grasses near the root. Mr. M'Lachlan gives a note of 

 Wallengren's determinations of the Trichoptera of Zetterstedt's Insecta 

 Lapponica. The Rev. T. A. Marshall recommends carbolic acid as a pre- 

 servative of insects from mites, Psoci, etc. The drawers and boxes should 

 be washed with a weak solution, which leaves no stain. The sheets of 

 card -board on which Coleoptera, etc., are to be gummed, should be medicated 

 in like manner. 



In the Journal of Botany from May to December, 1873, we find the 

 following: — "Additions to the British Lichen Flora" by the Rev. J. M. 

 Crombie, including many Scottish species. "Recent addition to our Moss 

 Flora, Part VI." by Dr. Braithwaite, in which the author discusses the Ortho- 

 trichacea:. Of the Orthotrkhece full descriptions and Lindberg's conspectus 

 of the European species are given. The generic name Ulota is replaced by 

 the prior Weissia Ehrhart (1779), the Weissia of Hedwig (1782), an utterly 

 different genus, being replaced by Simophyllnm Lindberg. ' ' On the distri- 

 bution of plants during the post-glacial period" by A. Nathorst. Dr. 

 Trimen gives a description and synomymy of the two forms of Rumex 

 obtusifolius L. — Friesii Gren. and Godr., the common British form, and 

 sylvestris Wallr. lately found beside the Thames. By some authors these 

 are considered distinct species. The great difference lies in the fruit, and 

 figures are given showing the distinction. R. sylvestris should be looked 

 for in Scotland — it occurs in Sweden. Baron von Mueller calls attention to 

 the probability of the occurrence of Chenolea hirsuta, a plant extremely like 

 Sutvda ?)iaritima, with which it grows. When the pubescence of the Chenolea 

 has become lost, the horse-shoe-shaped embryo affords a good distinction — the 

 embryo of Siuvda being circinate. ' ' On some Lycopodiaceous plants 

 from the Old Red Sandstone of the North of Scotland," by W. Carruthers, 

 F.R.S. (with a plate). "New British Fungi." by W. G. Smith, including 

 five Scottish species. Each number contains a list of the articles in the 

 botanical journals, both British and foreign, etc. 



In Grevillea, the editor (Mr. M. C. Cooke) continues his descriptions of 

 Fungi added to the British list since the publication of his Handbook. 

 These include a few Scottish species. "On the Rarer Lichens of Blair- 

 Athole " by the Rev. M. J. Crombie, includes 65 species, of which 8 are 

 new species, 7 new varieties and forms, and 7 others new to the British list. 

 Mr. Crombie remarks that there is a marked contrast in many respects be- 

 tween the Lichen Flora of the S. W. Grampians (Breadalbane), Central 

 Grampians (Blair- Athole), and N. Grampians (Braemar). "Addition to 

 the Lichen Flora of Great Britain" by Dr. J. Stirton, including six species 

 from Scotland. "New British Hepatica,' " by Dr. Carrington (whose 

 long-looked for work on these plants we trust will soon make its appear- 

 ance), including one Scottish species. There are besides several excellent 

 articles on structural and physiological botany, and each number has usually 

 a plate and list of recent cryptogamic literature. 



In Nature two articles on the geology of the "Southern Uplands of Scot- 

 land" by Professor Ilarkncss, are noteworthy.
