SHORT NOTES. 



British Eubi. — The Editor kindly allows me through the 

 Journal to ask my numerous correspondents on Rubi to send their 

 parcels of specimens for identification and criticism to the Rev. 

 H. J. Riddelsdell, Wiggington Rectory, Banbury. After a pre- 

 liminary examination and determination by him Mr. Riddelsdell 

 will forward them all to me, and so give my correspondents 

 the advantage of two determinations instead of one, while 

 appreciably lightening my work as final referee. I will under- 

 take to return the parcels to their owners as quickly as possible.

PoTAMOGETON Drucei. — When writing my review of British 

 Pond Weeds (Journ. Bot. 1915, pp. 186-8), I overlooked 

 Mr. Fryer's note in Journ. Bot. 1899, p. 524, which states his 

 reasons for considering this to be a vahd species rather than a 

 hybrid. Not having seen the book before its completion, I had 

 forgotten that it was brought out by instalments, and that some 

 of the opinions expressed at an earlier stage might have been 

 changed. It seems best to call attention to this important fact. —

Dialysis of the Corolla in Convolvulus arvensis L. 

 (Journ. Bot., 1915, p. 359). — Since the appearance of my paper, Mr. 

 Druce has kindly called my attention to a mention of a plant, 

 identical with those described by me, in his Flora of Berkshire 

 (1897), p. 357 ; to his having published a varietal name for it in 

 the Botanical Exchaiige Club Report for 1913 (p. 330) ; and to 

 his having there recorded a similar plant found in that year. The 

 original plant is in the herbarium of Charles DuBois (1656-1740) 

 at Oxford, having been found "near Henley" (which may mean 

 Oxfordshire or Berkshire) by the Rev. William Stonestreet 

 (1716), who describes it as " cum flore albo parva in 5 vel 6 lacinias 

 profunde dissecto." Though Stonestreet, who was Rector of St. 

 Stephen's, Walbrook, w^as a correspondent of Petiver, Plukenet, 

 and Buddie, he does not appear to have communicated this plant 

 to them — at least, it does not seem to have been published before 

 the issue of Mr. Druce's Flora. In the Exchange Club Report 

 Mr. Druce gives it the varietal name Stonestreetii, thus antedating 

 the name schizopetala proposed by me. The new record that Mr. 

 Druce adds is : " Aldeburgh, Sufi'olk, July, 1913, but not so 

 deeply cut." I now find that there is a specimen of Rand's plant 

 in the Sloane Herbarium (cxxii, f. 21), communicated by him to 

 Buddie. Following an example of the small-flowered form, it is 

 described as : " Convolvulus minimus flore etiam minimo nunc 

 integro ad centrum usque quinquepartito. — D. Rand." Buddie 

 died in 1715, the year before the death of Stonestreet, so that we 

 can only consider the finding of this form by the latter near 

 Henley and by the former, presumably, as recorded by Dillenius,
