" Scandinavian species ' ! may be used with reference 

 to plants described in the Scandinavian Floras but 

 not hitherto included in our own. 



Cerastium alpinum, L., var. glabratum. — Judging 

 from the appearance of the foliage and size of the 

 flowers of this the most beautiful of all the forms 

 of C. alpinum, it seems to occupy an intermediate 

 position between vars. pubescens and Edmonstonei. 

 I have no description of the plant, having been 

 indebted to Mr. A. Bennett, F.L.S., of Croydon, for 

 its identification ; and as the specimen now shown 

 is unfortunately the only one in my possession, 

 I do not care to destroy it in order that the 

 materials for a description may be obtained. 



I may remark that I have always believed the 

 plant formerly described as C* latifolium, Smith, to 

 be an unhealthy form of one or other of the varieties 

 of C. alpinum. I have, for a good many years, put 

 it in my exchange-list as a desideratum, but have 

 only got C. alpinum vars. lanatum and pubescens 

 sent me for it. This view seems to be supported 

 by The London Catalogue of British Plants (Eighth 

 edition, 1886), from which C. latifolium has been 

 excluded. 



According to my experience, C. alpinum var. 

 pubescens is simply the form lanatum grown in a 

 shady or moist situation, and therefore with greener 

 leaves and shorter pubescence. 



C. triviale, Link., var. alpestre, an alpine form of 

 an allied species, is distinguished from the typical 

 C, triviale by its more woolly pubescence and much 

 larger petals, which in well-developed specimens are 

 always longer than the sepals. It is a much more 

 straggling plant than any of the forms which C. 

 alpinum usually assumes, although I have speci- 

 mens of var. lanatum from Ben Laoigh and Ben 

 Lawers which seem in this respect to approach 

 var. alpestre.
