the way of determination of the species, and in the hope 

 that they may be willing to co-operate in their elucidation, 



Utricularia Brcmii, Heer., has often been suspected, but 

 its existence in Britain is still, I believe, not absolutely 

 proved (but see a valuable paper on this in Jour. Bot., 

 1876, 142, etc). 



Differences from U. minor, L., to be looked for are — 

 (1) robuster habit, (2) a more decided spur, which in U. 

 minor is scarcely longer than broad, and (3) an orbicular 

 lower lip. 



Some suspected localities are " Moss of Inshoch, Xairn, 

 and Loch of Spynie " — Bab. Man., ed. viii., 288. The 

 Loch of Spynie is near Elgin. " Near Glenluce " — on a 

 label, Hb. Ediub. B. G. Culdoch Moor, Kirkcudbright. 

 Loch Feoir, Assynt. Mr. F, M. Webb {I.e.) considered 

 the Loch of Spynie plant to be U. Brcmii, and " certainly 

 not U. minor." 



In the Loch of Spynie a slender form of U. vulgaris, L., 

 should be looked for, and observed while fresh. The 

 specimen in Hb. Edinb. B, G. does not look typical. 



An interesting species has been gathered on Gordon 

 Moss by Prof. Dickson in 1882, allied to U. neglect a, 

 Lehm., and possibly a form of that species, which deserves 

 study. There are three sheets in Herb. Edinb. B. G., 

 beautifully preserved, but unfortunately tlowerless. 



A plant somewhat similar to the one from Gordon Moss 

 has been sent me (by the Eev. E. S. Marshall, and may be 

 rightly named) as U. neglect a, from peaty bogs of Loch 

 Gaunich, Eannoch Muir, Argyll. ISTo flowers. 



Long Moss, near Faldonside, Selkirkshire, produces a 

 plant which is probably U. ncglecta, but I have only seen 

 flowerless specimens. 



The difficulty in determining the species of this genus 

 usually arises from the absence of flowers, or their poor 

 state of preservation when present. They are frequently 

 flowerless in rainy districts ; while, on the other hand, the 

 season of 1893 has given me abundant proof that a warm, 

 dry season favours the production of flowers. Having a 

 suitable locality for their development near at hand — 

 a shallow bog with a sunny e:!^posure — I am willing to try 

 and persuade to flower any critical or curious unnamed
