finely serrate leaves, and the slender twiggy, branching 
growth. The base of the bracts of the catkin below the 
black tip, is ferruginous. — J. Fraser. 
Salix caprea L. $ (Det. J. Fraser). [833]. Longmorn, 
Morayshire, June 19, 1928. — Leg. K. D. Little. Comm. 
J. E. Little. The gathering has been collected rather too 
early to show the large, wavy crenatures, characteristic of 
this species. The primordial leaves of this species are mostly 
entire, and only some of the longer summer shoots show the 
crenatures on the uppermost developing leaves. There 
are no striae or raised lines on the wood under the bark of 
this species, as the pieces of shoot from which the bark is 
removed will show. Striae or their absence are valuable in 
the determination of hybrids in this group. — J. Fraser. 
J uncus tenuis Willd. Abundant on stone paving by farm 
house, Rosemorran, near Gulval, W. Cornwall, Aug. 5, 1929 
(later specimens received Aug. 30,). A new locality for this 
plant, still rare in Cornwall. H. S. Thompson. It was rather 
rare in Surrey before the war, but since much of the timber 
was cut down this J uncus appeared on several of the Commons 
and along the canal banks. — J. Fraser. 
J uncus inf Lexus Linn (glaucus Ehrh.) [A. 15]. Littleworth 
Common, Esher, Surrey. August 31, 1929. J. E. Lousley. 
Sent for comparison with diffusus. — Yes ; J. E. Little. 
X Juncus diffusus Hoppe ( effusus X inflexus). [A. 18]. 
Growing with inflexus at Littleworth Common, Esher, Surrey, 
Aug. 31, 1929. Inflexus from the same locality is sent for com- 
parison. Although there was no time to search for it, I have no 
doubt that effusus occurs in the near neighbourhood. These 
specimens have the continuous pith, very small capsules, and 
the dark sheaths said to be characteristic of the hybrid. — J. E. 
Lousley. I see nothing characteristic in the sheath colouring 
of these plants, but agree that they are the sterile form of 
the hybrid. — E. C. Wallace. Yes — J. E. Little. I regard the 
specimen as all there is to represent the hybrid. The chief 
distinction between it and inflexus is the very much smaller 
capsule. J. inflexus Linn., sent with it, was quite correct. 
J . effusus Linn, is the most common species of this group in 
Surrey, and varies with loose panicles, and compact heads. — 
J. Fraser. 
Juncus maritimus Lam. var. congestus L. B. Hall. Near 
Poole Harbour, Dorset, Oct. 2, 1928 and Aug. 27, 1929.
