January of the present year. Various names have been conferred 

 upon the plant, which are now supposed, however, to include vari- 

 ous plants, specifically distinct, although confused in books. The 

 Rev. A. Bloxam, to whom the Society is indebted for specimens of 

 this and many other valuable plants, has used the unpublished name 

 of " Anacharis Alsinastrum " on his labels. Unfortunately, the spe- 

 cimens are destitute of flowers, and sufficient only for about a tenth 

 of the members ; for so large a supply is now requisite in order to 

 send to each member, that it becomes difficult to equal the demand. 

 By next winter, a more numerous supply may be hoped for ; and even 

 in their flowerless state the specimens can be readily distinguished 

 from all other British plants. It will probably be found in various 

 other counties besides Leicestershire ; and to those botanists who may 

 wish to search for it without having seen specimens, I would rudely 

 describe it as an aquatic monocotyledon, with verticillate leaves, and 

 general appearance between Callitriche autumnalis and Potamogeton 

 densus or perfoliate, although with flowers more resembling those of 

 Alisma. But in general form the Udora resembles the European 

 Elatine Alsinastrum more than any other plant known to me, if we 

 leave the flowers out of consideration. I might compare Udora with 

 the American Mayaca, were it not that such a comparison would be 

 like an attempt to convey some idea of the little known by reference 

 to that which is probably less known. 



Salix ? ("new species? 1 '). — Among various other species 



of this intricate genus, Mr. Ward, of Richmond, sends specimens of 

 one which he thinks may prove to be a novelty. The label intimates 

 that Mr. Borrer refers the specimens to Salix aquatica, an opinion 

 with which Mr. Ward does not concur. They are located from the 

 neighbourhood of Richmond, Yorkshire. 



Myriophyllum pectinatum (De Cand.). — Mr. Notcutt, to whom the 

 Society is indebted for a good supply of specimens, reported the dis- 

 covery of this plant in the ' Phy tologist ' for last year (see Phytol. ii. 

 1015). The specimens themselves may be received also as patterns 

 of perfection ; being good examples, well dried, and very neatly 

 labelled; the absence of the No. being of course unavoidable on the 

 label of a plant which was reported just too late to find place in the 

 ' London Catalogue.' According to the characters set forth in Koch's 

 Synopsis, some of the specimens might as correctly be referred to his 

 variety 'intermedium,' as to his variety 'pectinatum.' Doubtless Mr. 

 Notcutt might find the connecting links between this latter variety 

 and the more typical form of M. verticillatum in the same locality ;
