Syme, E. B. v. 191. 846. Nym. 444. 
Native (?) Walls. 
Sibthorp’s records belong to vulgatum; see Walk. Flora, p. 225, and Sir 
J. Smith, E. Flora, Baxter states he could not find a single specimen of 
murorum on Wadham walls, although there was plenty of vulgatum. He 
says there are no specimens of Sibthorp’s preserved in the Sherardian Her- 
barium; but when Sibthorp arranged that collection according to the 
Linnean System, he appears to have considered murorum, maculatum and 
Smith’s sylvaticum as mere varieties of the same species. 
The specimen of murorum of Baxter from Magd. Coll. Walks, June 15, 
1831, on faith of which murorum is included as an Oxford plant in 
Walker’s Flora, is only a form of vulgatum. The Rev. H. E. Fox informs 
me that a specimen he gathered on the walls of Blenheim Park corre- 
sponds closely with a plant named murorum by H. C. Watson. 
The record of this species for Oxford must be queried. [Gloster E.] 
* H. maculatum, Sm. Spotted Hawkweed. 
Syme, E. B. v. 195. 849. 
Alien. Waste places. P. July. Onrubbish. Christ Church Meadow, 
probably an escape from the Botanic Garden, where the plant is naturalized. 
** H, amplexicaule, L. 
Syme, E. B. v. 178. 835. Nym. 448. 
Alien. Old walls. Naturalized. P. June, July. 
Walls of Magd. College, Rev. W. Bree in Purton, 1824. Naturalized on 
walls of Oxford Botanic Garden. Mr. Bicheno says that it has an equally 
good right to a place in the British Flora as Senecio squalidus and some 
other plants, Walk. Flora, app. 308. Seems firmly established on banks 
of Cherwell near Botanic Gardens and on Magd. Coll. Walls, H. Bos. in 
Phyt. 1860, 101, see also Report of Lond. Bot. Ex. Club, 1867. 
Comp. Cyb. Br. 527. Oxford on walls there. Alien. 
Sibthorp’s H. cerinthoides was probably this plant, see Sib. pref. p. viil.
