﻿Morong (Mon. N. A. Naiadacem) gives pralongus as "fruiting in 

 June and July, and usually withdraws its stems beneath the water as 

 soon as the fruit is set " ; for perfoliate he gives " July-September," 

 not saying, however, whether that time is flowering or fruiting; 

 probably both. Though a single specimen is far too little material 

 to decide upon, one characteristic feature may be named, i. e., the 

 apex of the leaves are rounded, and one is split just as praslonge 

 does when dried, but this may be only accidental here. Generally 

 the specimen shows affinity with pralonge in its long peduncles, 

 spikes (no fruiting spikes on the sp.), its sub-persistent stipules, 

 and the apex of the leaves (?) ; with perfoliate, var., in its clasping 

 leaves, and venation. I have another specimen from Methye Lake, 

 lat. 57° (J. M. Macoun), that may also be this supposed hybrid; 

 P. perfoliate certainly grows in that lake, but I find no record of 

 prakmgu,, though it occurs in the Athabasca river (about 58°, 

 further north). This is only in bud, but its stipules are present, 

 and the apex of its leaves is apparently slightly cucullate. I thought 

 (before seeing fruiting specimens) that perhaps the western var. of 

 perfoliate might be this hybrid; but its fruit. is decidedly that of 

 pmfoliatus, though rather larger than the eastern American forms. 

 A series of specimens, with local observation, must decide whether 

 my supposition is correct or not. — Abthub Bennett. 



Potamogeton undulatus Wolfg. — To the distribution of this 

 form may be added Ireland (Six-mile Eiver, Co. Antrim, 5, 8, 82, 

 S. A. Stewart). Shropshire ; Ellesmere, in deep water, Sept. 1882, 

 W. E. Beckwith. These seem to be nearest to the var. Jacksoni 

 (cf. Fryer, Joum. Bot. 1891, p. 291). Another plant, gathered by 

 Mr. Beeby, " B. Wey, Stoke, Surrey, Sept. 1882," may belong 

 here, but the specimen is not sufficient to make sure it is so. 

 Other specimens (very young) from Anglesea (Aug. 1888, J. E. 

 Griffith) may also belong, and are very like some small specimens 

 sent as "P. perfoliate L." from America by Dr. Morong, and also 

 resemble his P. Mystice. For thirty years I have known P. crispe 

 growing mixed with P. perfoliate a few miles from Croydon, but I 

 failed to detect anything that could be held as between them, last 

 year ; I shall hope to renew the search this summer. — Abthur 



Wilts Eecords.— The following new plants have been found in 

 the county by myself and others, and duly verified since my notice 

 m Joum. Bot. 1893, p. 23. My thanks for critical help are due to 

 the same gentlemen as before, and also, as regards the Cryptogams, 

 to Mr. James Saunders and Mr. Boswell :—Rube Sprengelii Weihe.
