SHORT NOTES. 433 Chenopodium Vulvaria L. Sandy hollows on the Chesil Beach ; and on waste ground with the next species. — G. Jicifolium L. Two plants on waste ground between Weymouth and Radipole. This spot must be close to that mentioned by G. S. Gibson, who seems to have been the only other recorder of the species in West Dorset. — Juncus com- pressus Jacq. Occurs plentifully in a small pasture between the Fleet and Wyke Regis. Mr. A. Bennett considered the specimens to be probably the var. coarctatus Meyer, not before detected in Great Britain. The Flora contains no certain station for this plant. Bell- Salter wrote that it was ' ' very common in the neighbourhood of Poole," where, however, it has not been observed by later botanists. — Scirpiis paucijiorus Lightf. We have specimens from a swampy spot by a spring towards the Bill of Portland. This summer the place was dry, and the plant did not show. — Carex dioica L. Plen- tiful in a bog about half-way between Wareham and Corfe Castle, at a considerable distance from the two other recorded localities. In many plants the barren spikes had fruits at the base ; a form which would seem to be somewhat unusual, Dr. Boswell Syme, in E. B. ed. iii., observing that he had never met with it, though Prof. Babington appeared to have done so. This form was seen also last year in Agglestone Bog. — James W. White and David Fry. Additions to the known Flora of the South Ebudes, v.-c. 102. — During the early days of last September, I paid a visit, for botanical work, to the Island of Islay, which forms, with Jura, Scarba, and Colonsay, the group of the South Inner Hebrides. During my stay I was the guest of Dr. T. F. Gilmour, Port Ellen, the local medical officer, to whom, for his valuable co-operation, I was much indebted. Notwithstanding the advanced time of the year, some 340 phanerogams, ferns, and fern-allies rewarded search. Specimens of all of these were transmitted in the fresh state to Mr. Arthur Bennett, F.L.S., who has placed me under obligation by his kind help, and who informs me that my despatches include eleven species not hitherto recorded as occurring in v.-c. 102. The species are Buda marina Dum. var. neglecta (Kindb.) ; Potentilla procumhens Sibth. ; Erythrcea pulchella Fr., f. or var. ; Polygonum Rati Bab. ; Runiex conglomeratus Murr. ; Juncus alpinus Vill., which Mr. Bennett says is "good alpinus'* — genuinus of Buchenau, the monographer of the genus — this is the first record of the plant as a Hebridean spe- cies ; Sparganium minimum Fr. (?) ; Potamogeton decipiens Nolte ; Cladium jamaicense Crantz, abundant, and growing 6 ft. high in Loch Knock ; an interesting extension of the range of the species ; Deschampsia discolor Roem. & Schult., Loch Knock Marsh; Festuca rubra L. With the exception of an irregular belt of quartzite along its eastern coast, Islay consists mainly of graphitic mica schist, traversed in the middle of the island and from north to south by beds of a limestone which is quarried and used for commercial purposes. There are no mountains of consequence in Islay — the highest not exceeding 1800 ft. The area of the island (150,000 acres) consists chiefly of moorland, yet Islay is the richest and most productive of the Hebrides, and, apart from its coast-line, has considerable variety of situation for its indigenous vegetation. — A.
