SHORT NOTES. 319 



be merely a case of so-called rejuvenescence of the parent-cell. In 

 the case of Cosciuodiscus, 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 (Jhatoceras the state of things 

 resembled CoscinodiscHs, 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 Jjiddiilphia lacis and Xavicula scotica, as 

 Mr. Comber informed him. 



SHOUT NOTES. 



South Hants Plants (p. 135) — Mr. E. J. Tatum gives two 

 records for S. Hants, viz., Uosn stijlom Desv. and Crepis tara.caci folia 

 Thuill. Mr. Tatum omits to say that the Bosa has been found 

 frequently in its commonest form (s>/sti/!a 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 

 collectira are given in the Flora, and another form of fi. stijlosa is 

 mentioned on p, 415 of the Botanical Exchamje Cluh Bu'port (1893). 

 Grepis taraxacij'olia 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. niccBensis Balb., and 1 have seen it on a railway bank since, 

 between Christchurch and Brockenhurst, both localities in District 

 III of S. Hants. Chenopodinni jicifoliiun 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. 



Lepidiuji 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.
