NOTES ON NUPHAR PUMILUM AND N. INTERMEDIUM- 



BY ARTHUR BENNETT, F.L.S. 



TN the " Scottish Naturalist" for 1886 I noted that Dr. Caspary of 

 -*- Konigsberg had my specimens of the plants for examination, and I 

 promised then to give the results. This I now do, though I am sorry 

 my material v. r as so scanty, as it is evident that what is wanted is 

 the collecting of good specimens of all our smaller Water- Lilies. 



Nuphar pumilum Smith. 

 Ellesmere. Salop. Mr. Jones. 



" Seems to be N. pumilum although the stigmatic disk below the 

 rays seems to be even, &c." Dr. Caspary. 



This Salop plant I consider to represent Smith's plant exactly ; 

 and the following extract from a letter of Mr. H. C. Watson's, of Nov. 

 19, 1879, shows that he also so considered it : " Thanks for the 

 specimen of iV T . pumilum from Shropshire, a desirable one for my 

 herbarium, having myself raised a query as to the certainty about the 

 species there. It is curious that these species of the Highland lakes 

 should occur in Salop, but apparently not in any of the Welsh lakes- 

 The uncertainty which yet attaches to the so-called 'pumilum ' of 

 the Eastern Counties of England made me wish to make sure about 

 that of Shropshire." 



* The Botanical Exchange Club has this year distributed specimens 

 from Merioneth, Wales, gathered by Rev. A. Ley, as N. piunilutn 

 Smith. 



Nuphar ? 



Loch, Dumfries, Sept. 1885, collected by Fingland. 



"Nuphar luteum ^pumilum, Caspary, N. intermedium; Ledeb. : 

 That this plant is a hybrid there is no doubt, stigmatic disk entirely 

 even between the rays, axillary elevation present, anthers 2 to 4 

 times as long as broad, leaf hairless underneath," Dr. Caspary. 



Nuphar ? 



Sanquhar, Dumfries, Dr. Davidson, " N. luteum x pumilum? 

 Caspary. 



The same name Dr. Caspary gives to a specimen kindly lent me 

 by Mr. Beeby, also from Dumfries.
