I860.] ADDITIONS TO THE FLORA OXONIENSTS. 101 



and apparently rather as it might be found than because it had ever 

 been, like Solidago Virgaurea and one or two others, which I could 

 never hear had been seen by any botanist in the neighbourhood. 

 I searched in vain for the Anthriscus till last May, when it was 

 brought to me by a friend who had found it near Shotover and 

 Wheatley, and thought he had Caucalis daucoides, a pleasing 

 illusion I was obliged to dispel after examining the plant. Guided 

 by his directions, I went to the place, and found a small patch of 

 the plant growing, under the shade of a hedge-bank, with Are- 

 naria tenuifolia. In the same neighbourhood, and again at Bag- 

 ley Wood, and one or two other places, I found Viola flavicornis 

 {\QX. pumila, Hook, and Arnott), a very near relation, at least, to 

 V. canina. 



Medicago sativa occurs in several places, and also Trifolium 

 incarnatum, but doubtless introduced. The two seem to have 

 established themselves and assumed a wild aspect in some broken 

 limestone ground near Stow Wood. Hieracium amplexicaule 

 seems firmly seated on the bank of the Cherwell, near the Botanic 

 Garden, and again on the walls of Magdalen College. Of decided 

 aliens I have also seen the following : — Hypericum calycinuni, in 

 thickets in Nuneham Park, introduced from the not distant gar- 

 dens. Carum Carui, in a meadow off the Bothy road. Camelina 

 sativa, clover-fields near the Warneford Asylum, with Anthemis 

 arvensis, etc. Linaria purpurea, rubbish near the Great Western 

 Kailway station, not likely to become a fixed inhabitant any 

 more than the Carum. Aster Tradescanti, the Michaelmas Daisy, 

 seems firmly established, for in two or three places it has con- 

 tinued to flower for the last three seasons. Last autumn I met 

 with it frequently, and always far away from houses or gardens, 

 as in several places on the banks of the Cherwell, in Christ Church 

 meadow, whither it had probably come from the Botanic Garden ; 

 on the river-bank, near Louse Lock, and in hedges near the 

 Warneford Asylum, among a thicket of Brambles, amid whose 

 shelter it attained a height of four or five feet, like the Helminthia 

 echioides, with which it grew. This is a plant I have never seen 

 noticed as introducing itself into the British Flora before.
