from Skane up to Ostersunds Ian, and in Finland is on 

 record for twenty-three out of twenty-eight botanical 

 provinces. 



The account of the British species by Dr. Williams 1 is 

 very full, in which he quotes Meisters opinion' 2 that 

 U. major, Schmid., and vulgaris are one species, with 

 which I do not agree. Dr. Gliick in ;; Deut. Bot. Gesll3. " 

 (1902). p. 149. has a valuable contribution to the European 

 species. Syine in " English Botany " gives 18 inches as 

 the height of U. vulgaris, but Messrs. Burrell and Clarke 3 

 found it on E. Ruston Common "just over 6 feet in height."' 

 and on Foulden Common with flower stalks 15 inches long. 

 This is surpassed in U. major. I have specimens of the 

 /. gigantea* (sub neglecta) with flower stalks 20 inches long 

 and with fifteen flowers, some of the pedicels lj inches 

 long. An interesting note on intermedia may be quoted 

 from Messrs. Burrell and Clarke's paper : — "Intermedia in 

 a normal state is always anchored by the branches which 

 bear bladders only, either to the vegetation near the floor 

 of the pools, that which margins them, or more rarely in 

 the mud. As a consequence the hidden bladders and 

 bladder-stalks are usually bleached and semi-translucent, 

 contrasting vividly with the leaf stalks, which are of a 

 characteristic yellowish-green.'' 



I have to thank Dr. O. Xordstedt for kindly sending me 

 the original paper of Hartman " De Svenska arterna af 

 slagtet Utricidaria." 



Dr. Williams' record of intermedia (I.e.) "north to 

 Shetland. W. G. Beeby." will now be incorrect, as Mr. 

 Beeby's specimens are the largest specimens of ochroleuca 

 I have seen. They are 9 inches long, with bladder branches 

 6 inches, bladders f^ x -f^ of an inch, and leaves 1 inch long.
