R. line from Bedford to Bletchley cuts the county boundary, which has a soil so similar to that of Bournemouth, that locally the village of Woburn Sands, which owes its origin to the planting here of the railway station for Woburn (two miles away), is sometimes spoken of as the "Midland Bournemouth." Owing to the foresight of a former Duke of Bedford, the low sandy hills are clothed with Scotch fir as the predominating tree; and it is not difficult to imagine oneself, when walking through the woodland rides, in the Talbot Woods or Branksome Park of the southern watering-place. It struck me that it would be interesting to compare the brambles of these two districts; and on the last day of September, 1892, I was able to spend several hours studying this genus on both sides of the boundary. I will take those within the county of Bucks first. - BUCKS (24). These I find, after consultation with Mr. Arthur Bennett and Mr. G. C. Druce, to be new to the county:-Rubus plicatus W. & N. The Rev. W. Moyle Rogers thought this had a peculiar look; not that he had any other name to suggest; as a matter of fact, I think it is simply peculiar in being shade-grown; consequently the leaves lose their plicate character; I have specimens with just such flat leaves from Derbyshire, Norfolk, and Surrey. The panicle is not at all untypical. R. nemoralis P. J. Muell. (the ordinary umbrosus, auct.). In woodland, south of the village. R. pyramidalis Kalt. Wooded side of a wet lane. The specimens are denuded of the usual thick clothing under the leaf, owing to the wet and shady situation; but Mr. Rogers arrived at the same conclusion, independently, that the plant was R. pyramidalis. There were a few bushes visible; probably more in the wood. —R. Drejeri G. Jensen. Named for me by the Rev. W. Moyle Rogers. Only one bush was noticed. It struck me at once as a species I was not familiar with, at least in the living state.R. rudis Weihe. Only noticed in one spot: two or three bushes. This is a typical form of the plant, and identical with the Oxfordshire material which has been issued in Fasc. I. of the Set of British Rubi.-On a form of the hirtus group, found in fair quantity in the woodland just south of the village, Dr. W. O. Focke writes as follows: R. flaccidifolius P. J. Muell., I believe. It is distinguished from all forms of the hirtus group by its sepals reflexed in fruit." I am not aware that this has been noted for Britain before.-R. dumetorum W. & N. In hedgerows. R. Balfourianus Blox. A good typical form of this variable species; hedgerows, south of the village. Besides these I noticed R. Idaus L., in the woods; R. rusticanus Merc., R. leucostachys Schleich., and R. Radula Weihe, by roadsides, already recorded; also R. macrophyllus W. & N., abundant on the steep banks of a cutting in the road leading to Woburn, which, I understand from Mr. Bennett, has not been placed on record for the county, but Mr. Druce tells me he has it from another part of Bucks. Here I may mention that in College Wood, near Little Horwood, in a clay district of Bucks, I found the next day R. adornatus P. J. Muell., named for me by the Rev. W. Moyle Rogers, and very fine R. echinatus Lindl., in some profusion; both additional to Top. Bot. ed. 2. BEDS (30). Of the brambles observed in Beds, Mr. A. Bennett tells me that those new to the county are R. Lindleianus Lees, R. rhamnifolius auct. angl., R. rusticanus Merc., R. macrophyllus W. & N., a glabrate form rather harsh under the leaf, R. Radula Weihe, R. Balfourianus Bloxam, and a form of R. dumetorum W. & N., all of them in hedgerows on the side of Woburn Sands towards Aspley Guise. In one of these untrimmed hedgerows a large bramble-bush took my attention, which had the aspect of R. adscitus; it was, however, perfectly barren, and by degrees I arrived at the conclusion that it was R. Lindleianus rusticanus; a view in which the Rev. W. Moyle Rogers entirely concurs. On comparing this list of the brambles of Woburn Sands with those of Bournemouth, I am struck by the dissimilarity of the two lists. In fact, only the most ubiquitous of our British brambles occur at both places. BRYOPSIS CESPITOSA Suhr. Seal Island, Challenger! Shore of Kaffraria, Suhr. Geogr. Distr. Mauritius. B.
