WILD FLOWERS 133 



the whole the Botanic Garden cannot be said to have much 

 influenced the surrounding flora. 



Viscum album L., the Mistletoe which is so frequent on so 

 many trees in the Garden (p. 79), has been conveyed to some 

 tall Swiss Black Poplars in Christ Church Meadow, and 

 possibly to the Hawthorn in the Parks. 



In the Garden beds year by year, for the last eighty years, 

 appear self-sown Sisymbrium Irio L., Erodium maritimum, 

 and Ajuga Chamaepitys, and the same form of Bursa pastor is 

 which Baxter gathered there in 1820 still abounds. 



On rubbish carted away from the Garden and deposited 

 on waste ground on the Iffley Road, and in the Marston 

 Brickyards many alien species grew in 1910 ; these included : 



Atriplex hortensis, L. Leonurus Cardiaca, L. 



Atropa belladonna. L. Lychnis Coronaria, Desr. 



Barbarea verna, Asch. Malva verticillata, L. 



Blumenbachia insignis, Schrader Mathiola bicornis, Br. 



Datura Tatula, L. Potentilla recta, L. 



Doronicum austriacum, Jacq. Reseda alba, L. 



Glaucium corniculatum, Curtis Sisymbrium Irio, L. 



,, luteum, Scop. ,, strictissimum, L. 



Lamium garganicum, L. G. C. D. 



In addition to a few of those mentioned in Mr. Druce's list, Dr. Daubeny 

 noted Cochlearia officinalis and Euphorbia portlandica on the rockwork 

 near the South Tank, Lepidium iberis in front of the Entrance Gateway, 

 Erigeron acris on the South Wall, and Sedum dasyphyllum on the walls 

 and coping of the Conservatory. 



A short list given in the Gardeners' Chronicle for 1872, p. 733, mentions 

 the " ill-named Senecio squalidtis, the curious Impatiens parvi flora, the 

 quaint Claytonia perfoliata, the ill-smelling Hieracium amplexicaule, a neat 

 species of Gxalis [? corniculata\ the gay Centranthus ruber, and the 

 peculiar Ground Pine, Ajuga chamaepitys." 



And possibly of greater interest still, the Yellow Tulip, Tulipa sylvestris, 

 of Christ Church Meadows may have been a Garden escape. It was 

 found in 1869 by my friend Mr. Hatchett Jackson, growing near the ditch 

 which used to run along the south side of the Broad Walk, and his father 

 had specimens from the same locality in his herbarium at a much earlier 

 date (R. T. G.).
