them from those of any other British Cochlearia, and is 

 most apparent in var (c) and (a), and least so in (b). This 

 character is entirely lost in drying ; in fact, identification 

 by herbarium specimens of this genus is exceedingly un- 

 satisfactory, many of the characters becoming obscure. 



Utricularia ochroleuca, Hartman, and U. inter- 

 media, Hayne, as Scottish Species. 

 By Arthur Bennett, A.L.S. 



The first record of U. ochroleuca as a probable Scottish 

 species was in the " Annals of Scottish Natural History " 

 for 1903 (p. 123). A further note on p. 250 has been 

 wrongly referred to as editorial ; x whereas Dr. Trail had 

 not even seen the specimens, so that he could hardly suggest 

 them as Scottish. 



In the " Trans. Botanical Society of Edinburgh " xxiv. 

 (1910), p. 61, the plant is again named. 



These three references to certain specimens were made 

 on the assumption that our specimens were similar in size 

 to the original specimens of Hartman, one of which I 

 possessed from the original locality, by the kindness of Dr. 

 Nordstedt. On Dr. Gltick visiting us in 1911, on showing 

 him these specimens he at once assented to them, but also 

 showed that other specimens much larger must also be so 

 named, and in a few minutes I named some twenty speci- 

 mens to all of which he agreed. It then became at once 

 apparent that nearly all the specimens we had been naming 

 intermedia were ochroleuca, and that intermedia was a 

 rare species, in Scotland certainly, if not in England and 

 Ireland. 



Another difficulty that stood in our way was Neuman's 

 idea that ochroleuca was a hybrid (i.e. intermedia x minor), 

 and other specimens also were being given additional 

 names, so it was not surprising the doubts felt. 



In "Topi. Botany " (1883) and the Supplement, twenty- 

 nine counties are recorded for intermedia. I possess 

 specimens from seventeen of these, and in every case they 

 prove to be ochroleuca.
