Centr. 120. p. 155), and the author adds to these. A prominent 

 topic is the endemism of a number of British varieties and forms 

 as suggested by Drude and, Graebner (Bot. Cent. 122. p. 331). 

 Adherence to this view is expressed, although elevation to specific 

 rank is only claimed in few cases. The remainder of the paper 

 summarises additional facts, and the following are some given as 

 new to the British flora: Viola Riviniana Reichb. var. pseiidomira- 

 bilis Gregory; Sagina scotica Druce renamed in Opposition to Osten- 

 feld (Bot. Cent. 122. p. 330); Potentilla procumbens Sibth. var. siib- 

 sericea Wolf, X Erica Praegeri Ostenf., Euphrasia fennica Kihlm., etc. 



XII. Moss, C. E., Remarks on the Characters and Nomen- 

 cJatnre of some Critical Plants noticed on the Excur- 

 sion. (XI. p. 398—414.) 



The Points of general interest in this communication are sum- 

 marised by the author: 



1) Whilst it may be true that there are numerous endemic 

 forms of plants in the British Isles slightly different from forms 

 on the mainland of Europe, this hypothesis has no Claims to ac- 

 ceptance until the British plants in question have been very care- 

 fully compared with the nearest related forms of the European 

 mainland. 



2) The naming of a new sub-specific form collected in a parti- 

 cular locality is, in general, undesirable, unless at the same time 

 the form in question is compared with other known forms of the 

 species, and the distinguishing characters of these forms also care- 

 fully delineated. 



3) In some cases (e. g. Stellaria dilleniana), the polymorphism 

 of a species is of such a nature that is seems undesirable to name, 

 other than symbolically, the sub-specific forms which are known 

 to occur. 



In regard to 3) the author discusses at some lenght the possible 

 combinations according to presence and absence of glaucousness, 

 large petals, and many-flowered cymes; some of these have received 

 varietal names, but a symbolic method such as used by Mendelian 

 workers is proposed. 



The remarks extend over 30 species, more lengthy notice being 

 given to: Sagina scotica Druce, Ulex Galii, Oenanthe ßuviatilis 

 Coleman and Oen. phellandriian [aquatica), Vaccinium oxycoccus 

 var. microcarpinn, Salicornia spp., etc. Lindman's floristic work on 

 Polygonum aviculare is indicated from the British Standpoint; P. 

 heterophyllum , P. aequale, are recorded from Moss's observations 

 northwards to central Scotland, and P. calcatum from Scotland 

 has been confirmed by Lind man. W. G. Smith.
