Centunculus minimus, L., in Warwickshire.-- The first record 

 I find of the occurrence of this plant in Warwickshire is a manu- 

 script note in a copy I have of the ' Botanist's Guide,' 1805, which 

 is as follows:—" Centunculus minimus, Bull's field and near Moor 

 Hall, Sutton Coldfield. J. P. Cottage, Atherstone." My copy of 

 the ' Botanists' Guide ' formerly belonged to a Mr. Power, who, I 

 am informed, was one of the Professors of Cambridge University. 

 The next record is from Oversley Wood, near Alcester, where it was 

 found by Mr. T. J. Slater during a visit he and I made to that 

 place in August, 1878. During the present month (August) I have 

 bad the pleasure of finding the plant in a third Warwickshire 

 babitat, in damp sandy drives in a wood near Combe Abbey. In 

 both the above localities I find it associated with Pepfa 1 ortula 

 and Sagma apetala. This is an additional county record to those 

 given hi Mr. H. C. Watson's 'Topographical Botany.— James ih.

Potentilla Sibbaldi, Holler fil. - It appears that this is the 

 correct name of the plant which British botanists usually call 

 Sibbaldia procumbent, L. Mr. J. T. Boswell Syme (now J. 1, 

 Boswell), in < English Botany,' vol. hi., pp. 142-8 >, reduced Sibbahha 

 to a subgenus of PotenMa, styling our plant P. Sibbahha, ascnbmg 

 more than enough credit to William Wilson for pointing out the 

 insufficient characters by which the present species had been made 

 the type of a new genus and separated from Pfntdla .^SJ. 8 

 remark was published in Hooker's ' British Flora, ed. L (1830), 

 1>. 148, and remained unaltered through all the Buceesave nrfitaaM 

 -a period of thirty years. Grisselich, however, h^P*™* 

 made the same reduction in his comparatively unkno, n work, 

 ' Kleine botanische Ochriften' (1836) Sir J. I). Hooker* the 

 first to revive the name at the head of this note in Jfe Floi *J* 

 British India,' part v., p. 345 (recently issued, but not *«)» ™ 

 he is followed by Dr. Aitchison in his paper on the ™*»™I 

 Kuram Valley,' in the last number of the ' Journal of the ' I™» 

 Society.' The name Potentilla procuwbe, W>- Clairv., g ve n m toe 

 'Students' Flora,' ed. h., p. 120 (1878), is untenabl > ^use 

 already appropriated by Sibthorp, <F1. Oxon, p. 162 gWJ). J 

 take the following to be a correct statement so far as it goes . 



Potentilla Sihkddi, Haller fil. (1820).
