very dense, intricate patches. It is so very fragile that I found it 
impossible to clear all the specimens from Hyptium Wilsoni, etc., with 
which it grows.” — J. A. W. “ A long-bracted form, with spine cells 
well developed but deciduous.” — H. and J. Groves. 
Chara hispida, L., var. rudis, Braun. Loch Loy, near Nairn, vice- 
county 96, 29th July 1898. — E. S. Marshall and W. A. Shoolbred.

distributed from the same neighbourhood.” — H. and J. Groves.

Hie?’acium lasiophyllum, Koch., p. 522. “The hawk weed sent by 
me in 1896 from Cefn Coed without a name, and placed by Mr. 
Hanbury under H. lasiophyllum, Koch., was the plant described in 
the ‘Journal of Botany,’ 1898, p. 6, as H. hypochoiroides, Gibs., var. 
cyathis. I still adhere to the view there expressed that it should fall 
rather under H. hypochoeroides, Gibs., than under H. lasiophyllum, 
Koch.” — Augustin Ley. 
REFERENCES TO REPORT FOR 1897. 
Hieracium rigidum, Htn., \ax. irichocaulon, Dahlst., p. 556. “Mr, 
Hanbury and Mr. Druce both report that their specimens of the 
gathering of H. rigiditm, Htn., var. trichocaulon, I)ahlst., was H. 
boreale, Fr. I don’t dispute their verdict in the least; but, as having 
guided Mr. Ley to the railway bank at Parkstone, and helped him to 
gather the specimens, I may remark that I have not seen any H. 
boreale in that locality, and know that the plant we gathered together 
was what Am. Dahlstedt had named var. trichocaulon for me. The 
mixture or transmutation must have occurred later.” — E. F. Linton. 
Salix cinerea, Linn., p. 564. S.cmerea, L., from Clydach River, 
Monmouth, leg. Charles Bailey, is typical enough. The stipules are 
unusually cut, but this alone will not prove S. aurita present (as 
suggested) ; the leaves and catkins are good S. cinereal'' — E. F. 
Linton.
