3. U. INTERMEDIA, Hayiie. 

 Green assimilating leaves cpiite 



without bladders. 

 Leaf tip obtuse with a prickle set 



on the apical margin. 



Corolla bright yellow, or yellowish 

 .vhite, striped with purple. 



Spur subulate, yellow as corolla, as 

 long as lower lip to which it is 

 adpressed. 



Pedicels erect. 



Winter bud after germination retains 

 its original ball-shaped or 

 weakly elliptical form. The 

 section is egg-shaped, obtuse. 



Prickles. The tufts are either 

 situated on an extremely 

 reduced leaf-flap or directly 

 on its margin. 



5. U. MINOR, L. 



Corolla pale yellow. 



Upper lip as long as the depressed 

 and inconspicuous palate. 



Lower lip 6 mm. broad with re- 

 curved margin. 



Spur very minute, scarcely longer 

 than broad. 



BB. 



4. U. ocHROLEUCA, Hartm. 



Green assimilating leaves always 

 bearing sporadic bladders. 



Leaf tip gradually attenuated into 

 a long point which ends with a 

 fine bristle. 



Corolla sulphur yellow with brown 

 striae. Upper lip flat emar- 

 ginate. 



Spur conical gradually diminishing 

 from a broad base to the blunt 

 apex, half as long as and 

 standing apart from the lower 

 lip. Red -brown. 



Pedicels patent. 



Winter bud in germination extends 

 to more than twice its original 

 length. The leaves of the 

 winter bud are pointed at the 

 tip, and the indentation of the 

 leaf margin is stronger than in 

 intermedia. 



Prickles. The tufts of prickles at 

 edge of bud-leaves are less 

 numerous and not so strong as 

 in intermedia and are situated 

 upon a distinct leaf-flap. 



6. U. Bremix, Heer. 

 Corolla yellow, and more con- 

 spicuous than U. minor. 



Upper lip emarginate. Upper lip 

 5 mm. broad and long. 



Lower lip flat, not recurved at 

 margin, 9-10 mm. broad. 



Spur small ovate -conical. 



I. Utricularia vulgaris, L., is reported from 86 

 British counties from Cornwall to Shetland, but as Watson 

 points out, his enumeration includes negleda. Therefore 

 to be correct many counties require to be confirmed for the 

 restricted plant, which I have seen in 6, 14, 22, 23, 24, 25, 

 26, 27, 28, 31, 32. 



Probably some of the Scottish records may refer only 



to major.
