youth who accompanied me rediscovered Lysimachia thyrsiflora, 

 which, as T was told at York, had been sought for there in vain since 

 Mr. Woods observed it in 1835. We found it in very small quantity: 

 a remarkable circumstance of a plant that usually spreads so exten- 

 sively by root. I saw it and the Scheuchzeria in plenty in Leckby 

 Carr, in May, 1844. For the latter, however, I had a long search, 

 finding it at last about the middle of the bog, where it would be 

 scarcely accessible except in a particularly dry season. 



Myriophyllum alteriiifoUmn grows in Gormire, and Potamogeton 

 heterophyllus in abundance, and another Potamogeton, about which I 

 am in doubt. It has very long leaves and fruit- stalks, and the point 

 of the leaf is somewhat hooded ; whence at the time of gathering it I 

 supposed it P. praelongus. I met with it again, again accompanied 

 by the Myriophyllum, in the mountain pool in Place Fell, by Ulles- 

 water, called the Angle Tam. I saw the true P. praelongus in Win- 

 dermere, near the Ferry Inn, over against Bowness. I sought twice, 

 June and July, 1844, for P. longifolius in Rydal Water, Mr. John 

 Ball having given me a barren specimen so named, of his own gather- 

 ing in that place. I found a great quantity of P. heterophyllus ; and 

 upon subsequent examination, with Mr. Babington, Mr. Ball's speci- 

 men proved to be, in fact, of the same species. I am not aware that 

 the true P. longifolius (Mr. Ball's Irish plant) has been observed in 

 England. 



I have not seen the specimens of Mr. Ball's Linaria from "the rocks 

 of Coniston Water," of which Mr. Babington says, " If the seeds I 

 have with the specimens are correctly referrible to the plant (I have 

 no ripe capsules), it is a very distinct species, and as far as I have yet 

 seen quite new." It had been supposed L. italica. I found on a rock 

 by the road on the lake side, in quite a wild place, near Nibsthwaite, 

 a variety of L. repens with a white unstriped flower, which I saw 

 afterwards near Newby-bridge, on a dwarf wall facing a lawn by the 

 road to Stavely, and in gardens at Stavely and at Ambleside. I have 

 seen it also among the common L. repens, in Normandy, near Rouen. 

 I have not, indeed, examined the seeds, my specimens being in an 

 early state of flowering ; but I have no doubt that I refer it correctly 

 to L. repens. There seems reason to suppose the Truro and South- 

 ampton " L. Bauhinii," or L. italica, a hybrid between L. repens and 

 L. vulgaris, such as Dr. Bromfield has found in the Isle of Wight. I 

 believe that Mr. Babington now thinks the Irish plant different from 

 all these, and a specimen that he has given me looks so. L. purpurea 

 grows in some quantity on the ruins at Barnard Castle : I have seen
