230 NOTES ON OXFORD PLANTS. 



f. aprica Brnem, 5. — f. annua. Headington, 6. — E. palustre L., 

 var. lineare Kraus. Headington, 1886, 4. — f. ramosa. Otmoor, 

 Oxon, 4. 



Rippuris vulgaris L. — A submerged state, the var. fuviatilis 

 Roth also occurs ; it is Bauhin's Equisetum palustre, Linaria scoparia 

 folio. 



JEthusa Cynapium L., var. ayrestis Wallr. Not infrequent in 

 stubble-fields about Oxford. 



Anthrhcus vulgaris Pers. Charlton, Rogers, 4 ; Minster Lovell, 

 on the ruins, 5 ; Dr. Ayres in Hb. Baxter, 6. 



Scandix Pecten veneris L. The primary leaves are linear, much 

 resembling those of Myosurus. 



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. rubens Fleisch et Sind. Marston, 4. 



Petroselinum segetum Koch. Bicester, 4 ; Cowley Road, 6 ; Aston 

 Rowant, 7. 



Galium sa.vatile L. Hardwick Heath, 2. 



Yalerianella carinata Lois. Chiselhampton, 6. — V. rimosa Bast. 

 Near Goring, 7. 



Scabiosa arvensis L., var. pinnatifida Gray, var. integrifolia Gray. 



Bidens cemua L. Marston, 1886, H. E. Garnsey!, 4. — B. 

 tripartita L., var. Integra C. Koch. Marston. 



Senecio Jacobeea h., var. fiosculosus Gray. Kirtlington, 4. — S. 

 vernalis W. et K., so named by Dr. Boswell, is not the plant 

 of Waldst. et Kit, but a form or hybrid of S. squalidm. Our 

 plant has glabrous stem and leaves. The true plant is decidedly 

 hairy. 



Chrysanthemum segetum L. Hethe, Rev. T. Martyn, 2. 



Qnaphalium 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. 609, 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 — Sib- 

 thorp'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. pyramidata Vill. — F. 

 minima Fr. Fields near Stow Wood, 4. 



Solidago Viryaurea L. Checkendon, Rev. C. Abbey, 7. A third 

 Oxon station. 



Pulicaria dysenterica Gaertn, var. longiradiata mihi. Islip, &c. 



Cnicus arvensis Hoffm., var. setosus (Bess). River-side, Oxford, 

 F. T. Richards !, 5, 1888.— Var. horridm (Winim. et Grab.). Com- 

 mon. — Yar. mitis Koch. Marston, &c.
