230 NOTES ON OXFORD PLANTS.
f. aprica Brnern, 5.— f. annua. Headington, 6. E. juilmtre L.,
var. lineare Kraus. Headington, 1886, 4. — f. ramosa. Otmoor,
Oxon, 4.
Hippuris vulgaris L. — A submerged state, the var. fiuviatilis
Roth also occurs ; it is Bauhin's Equisetum pahistre, Linarm scopari/B
folio.
^tlnisa Cynapitiyn L., var. arjrestis Wahr. Not infrequent in
stubble-fields about Oxford.
Anthriscus vulyoris Pers. Charlton, Eogers, 4 ; Minster Lovell,
on the ruins, 5 ;
Dr. Ayres in Hb. Baxter, G.
Satndix Pecten veneris L. The primary leaves are linear, much
resembling those of JSbjosurus.
Cicuta virosa L. Mr. Fox was mistaken in thinking he had
seen it between Bicester and Middleton ; I greatly doubt if the
plant has ever been found in the county.
Pimpinella major Huds., var. r^ihens Fleisch et Sind. Marston, 4.
Fetroselmuiii segetum Koch. Bicester, 4 ; Cowley Road, 6 ; Aston
Rowan t, 7.
Galium saxatile L. Hardwick Heath, 2.
Yalerianella carinata Lois. Chiselhampton, 6. V. rimosa Bast.
Near Goring, 7.
Scahiusa arvensis L., var. jnnnatijida Gray, var. integrifolia Gray.
Bldens ccrmia L. Marston, 1886, H. E. Garnsey !, 4. — B.
tripartita L., var. intrgra C. Koch. Marston.
Senecio Jacokea Li., Y&r. jlosculusus Gray. Kirtlington, 4. S.
rernalis W. et K., so named by Dr. Boswell, is not the plant
of Waldst. et Kit, but a form or hybrid of S. squalidus. Our
plant has glabrous stem and leaves. The true plant is decidedly
hairy.
Chrgsanthemum segetum L. Hethe, Rev. T. Martyn, 2.
Gnaphalium uliginosum L,, var. G. pilulare Wahl. After
examining many thousands of specimens I at last met with the
above plant in a damp sandy field near Headington Wick, where
several plants occurred amidst a profusion of the ordinary form. I
suppose we should write it var. lasiocarpum Ledeb. ; see Fl. Ross,
p. 6U9, vol. ii, " acheniis hispidulis." G. dioicum L. Watlington
Hill!, Miss Smith, 1887, 7. A second locality for this very rare
Oxford plant, if, indeed, it still exist, on Woodcote Heath— Sibthorp's
locality—where I have sought in vain for it. In the above
locality it is limited to a few yards in extent, and is on the chalk
escarpment of the Chilterns, which I suggested was a likely place
for it.
Filago spathulata Presl. Headington, 6; near Stow Wood, 4.
This will probably have to be referred to F. pgramidata Vill. — 1^\
minima Fr. Fields near Stow Wood, 4.
Solidago Virgaurea L. Checkendon, Rev. C. Abbey, 7. A third
Oxon station.
Pnlicaria dgsenterica Gaertn, var. longiradiatn mihi. Islip, &c.

F. T. Richards !, 5, 1888.—Var. horridus (Wimm. et Grab.). Common.—
Var. )iiiii.'i Koch. Marston, S^c.
