the compact clusters of flowers. In E. Tetralix the twigs 

 are tomentose, not hairy, and the leaves lanceolate or linear, 

 pubescent above and mealy all over beneath. The following- 

 may serve as a description : 



Erica Stuarti, nov. hybr. Leaves in whorls of four, or 

 irregularly scattered, ovate-oblong or lanceolate, ciliate, 

 glabrous above, puberulous (mealy) beneath except on the 

 glabrous midrib, margins revolute ; young twigs hairy ; 

 sepals ovate-acuminate ciliate, puberulous towards the tip ; 

 corolla cylindric-urceolate, nearly white below, shadingupwards 

 to deep rose-purple ; stamens and styles somewhat exserted ; 

 ovary nearly glabrous with a few hairs upwards. 



A NEW FORM OF EUPHRASIA CURT A, FR. 

 By Prof. JAMES W. H. TRAIL, A.M., M.D., F.R.S. 



AMONG numerous gatherings of Euphrasies made by me 

 during 1900 and 1901, which Mr. Frederick Townsend, 

 F.L.S., very kindly examined and named for me, there was 

 one form of especial interest which he identified as previously 

 known to him only from the Shetland Islands, where it had 

 been found by Mr. W. H. Beeby on Serpentine hills about 

 200 feet above Baltasound in 1897, and from Wales, where 

 it had been found by Rev. W. R. Linton at about 1500 feet 

 altitude, on silurian and trap hills, near Bethesda, Carnarvon- 

 shire, in 1900. The specimens gathered by myself, on 9th 

 September 1901, were growing plentifully on the side of a 

 turf bank near the loch of Loirston in Kincardineshire, on 

 poor granite soil, at about 270 feet above the sea. 



This form Mr. Townsend regards as belonging to E. 

 curta, Fr., but as very distinct from any named form of that 

 plant. He has therefore given to it the name of piccola, as 

 a new variety, and has permitted me to make what use I 

 please of his manuscript. Of this permission advantage is 

 now taken to give his description and diagnosis below, as pre- 

 pared from the specimens brought from Shetland by Mr. Beeby.
