a closely imbricated rosette at the end of the shoot. In reflexum 

 the branches of the panicle spread widely, and present a peculiarly 

 stiff and rigid aspect : in albescens and elegans they are much 

 more graceful and slender. In albescens the petals are narrower, 

 and paler in colour than in either of the others, and the sepals 

 are also narrower (they may be called elliptical in elegans, ovate- 

 lanceolate in reflexum, and lanceolate or linear-lanceolate in 

 albescens) . If, following out a recent suggestion of M. Crepin's 

 {' Notes sur quelques Plantes rares ou critiques de la Belgique^), 

 this section of the genus was divided into a couple of groups of 

 species, characterized, the one by granulose carpels and ciliolate 

 filaments, the other by smooth carpels and filaments, reflexum 

 and albescens would belong to the former of them, elegans to the 

 latter. At the date when this note is written (late in July) re- 

 flexum and albescens are in full flower, whilst elegans was in flower 

 a month ago, and now all the petals have fallen, the stems are 

 denuded of leaves, and the fruit is nearly ripe. The stations 

 mentioned for albescens (under the name of glaucum) in the 

 ' British Flora ' are rough hills near Mildenhall, in Suffolk, and 

 Sunday's Well and Glaskeen in Ireland. Upon the Continent it 

 is reported from France and Italy. 



'' Galium commutatum, Jordan. During a recent visit to Tees- 

 dale, in company with three of our members, this species was met 

 with on the Yorkshire side of the river, amongst the debris below 

 Cronkley Scars, on the sugar limestone on the top of Cronkley 

 Fell, and on the scar limestone of Mickle Fell, and on the Dur- 

 ham side of the river on the sugar limestone on the summit of 

 Widdybank Fell, so that the range of elevation in the district is 

 from 450 to upwards of 800 yards above the sea-level. 



" Carex rigida was met with on the Gritstone Peak, at the 

 west end of Mickle Fell, at an elevation of upwards of 850 yards. 

 It is near to Yorkshire, but was known previously as a plant of 

 the Tyne and Lake provinces, and also as an inhabitant of North 

 Wales. 



" Hypnum aduncum, Linn. {H. exannulatum, Bryol. Eur.). New 

 at the time to North Yorkshire, was picked by Mr. J. H. Davies 

 in boggy ground at Upper Cronkley ; and I have since seen it in 

 plenty in Cleveland, about the springs at the head of the northern 

 or Ingleby Greenhow branch of the Severn.
