VOL. XIX. (2) FLORA OF THE GLOUCESTER DOCKS

with almost black flowers, grew close by, and both the last 
two turned up again the following year. I have seen traces 
of a vetch there since, but the spot is very exposed to the 
ravages of children, and it never came to flower. With the 
doubtful exception of V. hithynica I fear all these vetches 
must be classed as casuals. Vida hirsuta has appeared on 
several occasions, and, when it does occur, is in considerable 
quantity. Cicer aietimmi, a foreigner, with pretty pink 
flowers and rose-like leaves, appeared in 1911 and 1912, and 
the handsome Coronilla varia in 1910-11-12 and ’13. The 
appearance of a factory destroyed the habitat of this last in 
1914, but I am glad to say that it broke out last year not far 
from the old spot as luxuriantly as ever. It grows, I might 
add, inplent^qon dredgings further down the Berkeley Canal. 
Others of the Pea group appearing are Medicago sativa and 
M. Falcata, Melilotus alba (1911 and 1912) and M. indica, 
Trifolium fragiferum and, last year. Trifolium arvense, one small 
plant. Of these, Medicago Falcata is abundant and quite 
permanent, whilst Melilotus indica is becoming increasing^ 
common. It is somewhat odd that Trifolium fragiferum is 
abundant in all the fields at the base of Churchdown Hill, 
but does not seem ever to climb the slopes. 
Potentilla argentea grew in some plenty on one spot near 
the Docks in 1912, but I have not found it there since as a load 
of rubbish was shot over it. Of the Willow-herbs the following 
occur : Epilobium angustifolium variety br achy car pum, E. 
parviflorum, E. roseum, E. montanum, E. hirsutum, E. obscurum 
(probably), and more certainly the less common E. tetragonum. 
Several of these hybridise, I believe, and all are apparently 
permanent. (Enothera biennis I found once. 
Sedum acre is always present at one spot, otherwise stone- 
crops and saxifrages are notable absentees. Of the umbel- 
liferous plants, the most interesting are Conium maculatum, 
Heracleum giganteum, Anthriscus vulgaris, Scandix pccten, 
Torilis nodosa, Apium graveolens, Buplcurum rotund i folium 
(1912), Caucalis daucoides and Caucalis latifolia (both in 1912) 
and Coriandrum sativum (1912 and 19^4)- these I should say 
the Conium is native, the Anthriscus and Apium are both 
naturalised and all the others casuals. The Buplcurum met
