8b BRITISH SPECIES OF UTRICULARIA. 



first with tlie direction of the spur, but divergent (nearly to the 

 extent of a right angle) before expansion. The pedicels are slender, 

 long in proportion, and usually straight or nearly so ; erect or 

 ascending in fruit (not recurved). The sepals and bracts are smaller 

 and of a browner green. Flowerless specimens may be distinguished 

 by the usually smaller (and more numerous '?) bladders upon the 

 leaves, the more slender leaf-segments, and the stems being 

 more disposed to branch than in U. vulgaris. It struck me, in the 

 specimens gathered last summer, that it Avas more easy to shake the 

 leaves of U. negleda out of the pencil which their segments form 

 when drawn from the water, and that the winter buds in their early 

 stages Avere more slender, than was the case in U. vulgaris. 



These numerous points of difierence sufficiently show that 

 these two are good species, though superficially, and especially 

 in the herbarium resembling one another, and in the past often 

 confused, 



Reichenbach has given a leaf-distinction, which I have not 

 succeeded in verifying, or finding confirmed by other observers. 

 He says that the serrations of the young leaves of U. vulgaris bear 

 a fascicle of bristles, while those of U. negleda have but a single 

 bristle, and he doubts whether the single bristle is always present 

 (Icon. Fl. Germ, et Helv. xx., p. 113, tab. 1822, 1824). 



Utricularia intermedia, Hayne. Stems more or less branched, 

 bearing large bladders on longish slender stalks or small branches, 

 and producing here and there terminal leafy shoots devoid of 

 bladders, terminating in hirsute winter buds ; bladders ^-1-oin. 

 long (sometimes almost ^in.), usually very pale ; leaves -|-f in. long, 

 roundish (eventually pointed) in outline, spreading regularly and 

 nearly in one plane, trifurcate at the base, then branching 

 alternately, rarely bearing a casual bladder, segments linear- 

 acuminate, often rather broad, dentate towards the extremities ; 

 scape, 2^--4in. curved below, but erect |-f of its length, 2-3-flowered, 

 with one detached amplexicaul cordate-acuminate bract ; pedicels 

 \-\m. long, decurved at the top, exceeding their bract ; calyx pale 

 green, lobes ovate to ovate-acuminate concave ; corolla ^in. (as
