1 66 YORKSHIRE NATURALISTS' UNION. 



1249. Triglochin palustre. Arrow-grass. Boggy places, not 

 common. Near Sharow mires ; Marfield, Masham 

 (Mrs. Berkeley). 



1251. Scheuchzeria palustris. Leckby Carr (Baines); 

 this writer states (1840) that he looked for this plant 

 for five seasons without seeing a single plant. After 

 this it would seem to have re-appeared. Mr. Lees 

 found a specimen, and a certain nursery gardener not 

 far from the place found, I am told, several, and re- 

 moved them all. Since then all efforts to find it have 

 been in vain. Mr. Lees, the Rev. W. Fowler, and I 

 sought the place minutely in 1881, guided by Mr. 

 Lees' previous experience. Since this, I went several 

 times the same year, paying special attention to the 

 spot where Mr. Lees found his specimen, but am 

 reluctantly obliged to consider it extinct. The first 

 record of this plant at Leckby was that of the Rev. 

 J. Dalton, in July, 1820. It is possible that it may 

 re-appear, but no botanist must expect to find it again. 



1253. Alisma plantago. Water plantain. Stiller parts of the 



Ure, ponds, &c. Not rare. 



1254. A. ranunculoides. Lesser water plantain. Pondsand 



ditches, occasional. Copgrove and Boroughbridge 

 district (Baines and Lees) ; Pilmoor Carr, near 

 Sharow ; on the common at Ripon (Baines). 



1257. Butomus umbellatus. Flowering rush. Ponds, 



ditches, and slow streams, rare. Ure near Newby 

 (Miss Morton) ; near Masham (introduced) ; it also 

 grows in small quantity in a pond near Ripon, where- 

 of I forbear to specify the place exactly. 



1258. Hydrocharis morsus-ranae. Frog-bit. I am not 



sure whether this plant is found near Ripon still. It 

 formerly grew in a pond in the Bull Close, as Miss 

 Morton informs me, from whence I have seen un- 

 doubted specimens. It also grew in the Staveley 



Trans.Y.N.U., 18S3 (pub. 1884). Series E
