Wahlenbergia hederacea (Reich) was seen on the side of the track leading 
from Caerphilly to Castel Coch and Rubia peregrina, L. on the mountain 
limestone above the Castel. The single Rocket, L. grew in a hedge about a 
mile from the latter place, no doubt an escape from some garden. The lane 
near Caerphilly’was beautifully fringed with ordinary ferns; Athyrium /ilix 
Femina, Berch, Polystichum aculeatum, Roth, Lastreea filix mas., Presl. L. 
oreopteris, Presl. sparingly, and Blechnum boreale, Sw. 
The plants observed in the Cardiff dockyard were Trifolium maritimum 
Huds, and T. resupinatum, L., Lepidium ruderale L., Erysimum orientale Br., 
Caricus tenuiflorus, Curt, and Diplotaxis tenwifolia D.C., which was most dis- 
agreeable in its odour. A single plant of Centaurea calcitrapa, L. was also 
met with. The time bestowed on the dockyard was not sufficient for a proper 
investigation of its flora, or probably other local or uncommon species would 
have occurred. 
Rosa villosa L. or tomentosa Sm. was conspicuous in several places around 
Cardiff for its deep red blossoms and its fragant and glandular leaves. 
Equisetum sylvaticwm, L. is common in that district, which, though abund- 
ant further north, is rare or unknown about Bath. It is, perhaps, the most 
elegant of the genus, and very ornamental when well grown, but it spreads 
to such an extent beneath the surface of the soil as to become a pest in 
gardens. 
September Tth. Excursion to Avebury and Silbwry Hill_—By a 
resolution passed at the Quarterly Meeting in July an alteration 
was made in the day of this Excursion from the 28th to the 7th 
of September. 
Notwithstanding the associations which the very name of 
Avebury calls up only thirteen members of the Club assembled 
at the rustic little station of Calne for this the fourth and last 
excursion. After ashort preliminary arrangement with mine host 
of the Lansdowne Arms we were well away for the Downs; once 
through the suburbs of the little town, the rounded outlines of the 
chalk hills appeared on our right, and the Cherhill White Horse, 
work of the last century, stood forth sharply defined by the 
morning sun in all its rampant obtrusiveness. Passing under 
Lansdowne Column which rises out of Oldborough Castle, one of 
the many camps studding the brow of the chalk escarpment in
