SHORT NOTES. 377 



Witcbell, thinking be might put them to good use. Unfortunately 

 for Prof. Babington's queries, when the Flora was published I dis- 

 covered everything put down with that certainty which belongs to 

 ignorance. Fortunately I have the plants and original notes, in 

 the Professor's handwriting, in my possession. — J. Henry Burkill. 



POTAMOGETON UNDULATUS Wolfgang, IN CAMBRIDGESHIRE. Mr. C. 



A, Billups found this species at Benwick, in a ditch by the side of 

 Parsonware Drove, where it grew with its parent species, l\ crispus 

 and jP. perj'oliatus. Several rootstocks were found, but as they 

 were all in a space of twenty yards along a shallow ditch, they 

 probably all spread from one seedling plant. The Cambridgeshire 

 form is nearer Wolfgang's type than any British specimens I have 

 seen from other localities, ditfering only by its somewhat shorter 

 internodes and leaves, just such differences as would occur between 

 plants grown in shallow and deep water. Very few of the stems 

 were in flower, and the foliage of them did not differ from that of 

 the barren stems ; in this respect agreeing with Wolfgang's plant, 

 and differing from the var. Cooperi, which usually assumes more or 

 less of a nitens look when in ffower. All the spikes were barren ; 

 and although I have had forms of unduiatus under cultivation for 

 three years, I cannot succeed in getting any fruit, although 

 artificial fertilization has been repeatedly tried. Mr. Billups tells 

 me he has also found this species on the Flintshire coast of the Bee. 

 I have now seen it from four English counties, and from Stirling ; 

 probably it will occur in many others. It should now be looked for, 

 as it grows throughout the winter like P. crispus. — Alfred Fryer. 



Chrysocoma Linosyris in Lancashire (p. 309). — This had been 

 recorded on the authority of Anthony Mason, of Grange-over- Sands, 

 in Aspland's Guide to Grange. These records until recently were 

 regarded as untrustworthy, but one of them, Orchis pyramidaUs, was 

 continued last year (see Naturalist for March, 1892), and now Mr. 

 Worsdell finds another plant which I for one have sought for in 

 vain. Perhaps more confirmations may occur.— Lister Betty. 



Lagurus ovatus in Jersey. — During my visit to Jersey in 

 September, I found a few plants of Layuras ovatus L. I found 

 them growing in the sandy waste of the Quenvais, at the southern 

 end of St. Ouen's Bay. I notice that in the last edition ot 

 Babington's Manual this grass is limited to Guernsey.— C. S. 

 Nicholson. 



Ranunculus petiolaris in Ireland ?— Mr. Britten has called my 

 attention to a buttercup in the British herbarium at B- Kensington, 

 collected by Mr. Dyer on the shore of Loch Bofin, Druinod, Co. 

 Leitrim, on May 30, 1871, and strangely labelled by him - ? expanded 

 pseudo-reptansr This is very near my plant, and should perhaps 

 go to it; but there are three stems from one root (always solitary in 

 the Scotch form, as tar as my experience goes), the habit of growth 

 is more compact, and the stem-leaves are more numerous and 

 closer together. The facies approaches more nearly to that oi U. 

 Flammuta than I have observed to be the case in 1L petiolaris. It 

 deserves further investigation.— Edward S. Marshall.
