PBOCEEDINGS OF THE 



The Eev. E. S. Makshall showed the following interesting 

 British plants : — 



" Saxifraga nivalis X stcllaris, n. hybr., found in 1902 on Cairn- 

 gorm by the late Mr. E. C. Crawford, F.E.S.E. (after whom, it 

 was proposed to name it). Specimens only in flower, but quite 

 intermediate in character. 



OrcJiis . Eound by Mr. "W. A. Shoolbred and himself, in 



quantity, at Inchnadamph, W. Sutherland. Clearly a new form, at 

 least for Britain ; allied to 0. macidata, L. A drawing by Mr. E. 

 W. Hunnybun is shown, besides good specimens. 



Helianthemum Chamcecistiis xpolifoKum, from Burn Hill, Bleadon, 

 N. Somerset. First observed by Mr. H. S. Thompson. A good 

 intermediate ; apparently quite fertile. 



Hieracium Jiyj^arcticum (Almq.) Elfstrand. First found by 

 Mr. F. J. Hanbury and himself in 1890 at Inchnadamph, and 

 again gathered in 1908. A modification of a South Greenland 

 species. 



Hieracium eustales, Linton, from E. and W. Sutherland. An 

 endemic species, previously known only from about four Berth- 

 shire stations." 



Mr. Henry Groves remarked upon the excellence of the 

 dried specimens exhibited. 



This exhibition was followed by Brof. F. E. Weiss, who showed 

 some specimens of Comjisopogon, a tropical freshwater alga 

 belonging to the Bhodophycese, which has been found in the 

 Beddish Canal near Stockport. The water in this part of the 

 canal is warmed by the inflow of hot water from the cotton mills, 

 and other subtropical aquatics have been found there in the past 

 — Naias graminea, Chara JBraunii, and Pitliopliora Oedogonia. 

 They are supposed to have been introduced with refuse from the 

 cotton mills. 



Brof. A. Dendy, Sec.L.S., exhibited lantern-slides and prepara- 

 tions which throw hght upon the structure of the Bineal Eye of 

 Splienodon. 



The Chairman, Brof. Herdman, and the Eev. T, E. E. Stebbiug 

 took part in a short discussion, and Brof. Dendy replied.
