St. Thomas’s Church. But it is only a question of time how soon the 
locality will be built over, as the plot is on .sale, and three of its sides 
already front roads or dwelling-houses. The frequent strong gales in 
the spring of 1903 drifted large quantities of sand on to the stations 
where the Ambrosia occurs, but the mode of growth just described 
has not interfered in the least with the growth of the plant. The 
plants, if anything, were more vigorous in 1903 than in the preceding 
year, and as the pistilliferous specimens are more developed this 
season a better supply will be sent than was available in 1902. 
It is not easy to determine in what way it has established its foot- 
hold at St. Anne’s. The older residents inform me that at one time 
the site was used for hen-pens and hen-runs, similar to those which are 
found at the southern end of the same group of sandhills, and I 
hazard the conjecture that the fowls have been fed, at times, with the 
grain sweepings of the docks, from Fleetwood or Liverpool, in which 
fruits of the Ambrosia have been included. 
Besides CEnothera bietmis, L., and Sisymbrium pannonicum, Jacq. 
(the latter contributed last year, p. 5), there are several interesting 
native plants associated with it on the St. Anne’s sandhills, besides 
the ubiquitous Saiix repens, L., and Rubus ccesius, L., viz.. Reseda 
lutea, L. ; Viola Curtisii, Forster; Cichorium Intybus, L. ; Hieracium 
umbellatum, L. ; Convolvulus arvensis, L. ; Echmm vulgare, L. ; Bartsia 
viscosa, L. ; Thymus Serpyllum, Fr. ; Polygonum Convolvuhis, L. ; etc. 
But there are several others growing with the Ambrosia which, though 
native plants, may have been introduced in the same way, viz., 
Lepidium ruder ale, L. ; Lactuca virosa, L.; and Marrubium vulgare, L., 
the first and last of which I have also found in other localities in the 
neighbourhood. — Charles Bailey. 
Senecio viscosus, Linn. By side of river Cynon, on Breconshire 
bank, August 1902. New county record for county 42. Washed 
down from Hirwaun, a mile away. The borders of Breconshire just 
reach the industrial parts of Glamorgan and Monmouth, and so county 
42 shares the alien records of its two neighbours at such points as 
Hirwaun, Merthyr, Brynmawr, and other places along the railway from 
Dowlais to Abergavenny. — H. J. Riddelsdell. 
Saussurea alpina, DC. Ben l.)earg, East Ross, vice-county 106, 
July 1902, New county record. — G. Claridge Druce. 
Crepis taraxacifolia, Thuill. Grass field on Henbury Hill, West 
Gloucester, 21st June 1902. The records for this species in ‘Topo- 
graphical Botany ’ are comparatively few, but the plant is believed to 
have spread rapidly in this country of late years, and is certainly more 
frequently met with about Bristol than it was formerly. In some 
districts, however, a good specimen may still be difficult to obtain. — 
Ja.s. W. White. “1 have seen fields in Surrey in which this species 
occurred by thousands; along every new road made in this parish 
(Croydon) the [ilant occurs, sometimes by hundreds. I believe it is 
a native only in very few counties.” — Ed.
