CORNISH FLORA. 71 



Nitflla gracilis, Agardh. Mr. Groves thinks that there can 

 be no manner of douht that the Rev. W. S. Hore's Goonliillv 

 record in tlie Ph/tologist, 1 845, refers to N. opaca^ Agardh, and 

 that N. gracilis sliouhl therefore be deleted. 



5. VARIOUS NOTES. 



There are a few items which demand special attention. On 

 page 55 of my List mention is made of a strange clover which 

 appeared at Falmouth Docks, and which I suggested might 

 possiblji be Trifolium oc/iro/cucon, Huds. I had previously taken 

 specimens to the National Herbaria at the Eoyal Botanic Gardens, 

 Kew, and the British Museum, but could not match them with 

 any of the British or Continental examples of ocIiroh'Kcon, or 

 indeed with any other clover. Dr. Otto Staph was induced to 

 take the matter up, and after a careful comparison of the plant 

 with a number of species in Continental Herbaria he came to 

 the conclusion that it was a variety of TrifoJinin albidum, Retz., 

 previously unknown to science, and to which he has given the 

 name ramosnm, Staph. At a meeting of the Linnean Society, on 

 June 5, 1902, Dr. Staph read an interesting paper on the subject, 

 and exhibited specimens of the new variety, together with 

 Continental examples of the species. It seems that the species 

 was in cultivation in various botanic gardens on the Continent in 

 the early part of the last century, and that it was grown at Kew 

 as late as 1856, though where the Kew specimens came from no 

 one appears to be able to say. 



Pinguicula grandifora, Lam. For many years botanists have 

 been concerned about the presence of this plant in Cornwall. 

 Not that anyone ever doubted its introduction, as it is a matter 

 of common knowledge that the only places in the British Isles 

 where it has any claims to nativity are a few favoured parts of 

 Kerry and Cork, in Ireland. In West Cornwall it is known as 

 " Dr. Ralfs' plant," and it has puzzled students of plant 

 geography to understand Avhy so eminent a botanist as Dr. Ralfs 

 should interfere with our flora by introducing a plant which has 

 no more right to a place in " the first and last county " than the 

 Man or Monkey Orchis has. Mr. E. D. Marquand has recently 

 pointed out to me that Dr. Ralfs did not intentionally introduce 

 this rather handsome plant. Specimens were sent him from
