SHORT NOTES. 319 be merely a case of so-called rejuvenescence of the parent-cell. In the case of Coscinodisciis, where preliminary divisions of the contents into eight and sixteen took place, it appeared to be reproduction by the free-cell-formation of new Diatoms, in their early stages capable of growth. In the case of Chatoceras the state of things resembled Coscinodiscus, but differed from it, since merely spore- like bodies were formed so far as had been observed. In all cases, whether one new Diatom or two, or eight or sixteen were formed within the parent, the result was a reproductive process of a kind not yet recorded in Diatoms, except in the case of the occurrence of a young Biddulphia aurita within the parent, as observed by Prof. Cleve, and in the case of Biddulphia Itevis and Navicula scotica, as Mr. Comber informed him. SHOUT NOTES. South Hants Plants (p. 135) — Mr. E. J. Tatum gives two records for S. Hants, viz., liosa stylosa Desv. and Crepis taraxacifolia Thuill. Mr. Tatum omits to say that the Rosa has been found frequently in its commonest form (systijla Bast.). It is recorded in Townsend's Flora for Districts III, VI, VII, VIII, and for Districts I, II in this Journal (1889, p. 14) ; two other vars. of this species collectiva are given in the Flora, and another form of R. stylosa is mentioned on p, 415 of the Botanical Exchange Club Report (1893). Crepis taraxacifolia Thuill. seems to be spreading from county to county, and is no doubt often a recent introduction ; it occurred in a field of artificial grass, near Sway, in 1890, in company with C. nicaensis Balb., and I have seen it on a railway bank since, between Christchurch and Brockenhurst, both localities in District III of S. Hants. Chenopodium Jicifolium L. appeared at Porchester in 1893 as a similar example of probable introduction, having other casuals in its company ; it may however be replaced in the list for S. Hants (see Townsend's Flora, p. 293). — Edward F. Linton. Lepidium Draba in Ireland. — A fresh specimen of this has been sent me to name, from the roadside near Enniscorthy, Co. Wexford, It was found only in one spot, but as the species frequently establishes itself, it may be well to put the occurrence on record. — James Britten. Vaccinium Oxycoccus in Somersetshire. — I was fortunate enough to find in a sphagnum bog on Blackdown, one of the highest of the Mendip range of hills, a small patch of Vaccinium Oxycoccus nicely in flower on May 30th, and again yesterday. I learn from Mr. W. White that it has only been found so far in one other locality in Somersetshire, the turf-moors near Glastonbury. It is many years since it was seen there, though it has been often searched for since. The patch on Blackdown is very small, a couple of yards or so either way, but having been now once found on the Mendips, I hope it may be found to grow in other localities there— W. F. Miller.
