BOTANICAL RAMBLES IN WEST NORFOLK. 267 
6 ft. in length. Some of the pools were carpeted with vulgaris, 
not in a free-floating condition as it usually is, and in one 
square yard of water there were 31 flower-stalks, some with 
three fully-opened blossoms. The flower-stalk is generally 
from 3 to 9 ins. in length, but in one of the deep ponds on 
Foulden Common there were flower-stalks 15 ins. On 
Flegg Burgh Common it occurred in such profusion that 
the bladders crackled audibly as we walked through various 
parts of the marsh, the same noise being made when any of 
the strands were drawn from the water. The crackling was 
not from those on which we trod, but appeared to come from 
plants a foot or two distant, and may have been due to the 
egress of air from the bladders. 
Utricularia minor seems hardly less abundant than vulgaris. 
It appears rarely to be quite free-floating, being generally 
interwoven with moss, Chara, or roots of Juncus or Carex, 
with the hidden portions devoid of colour, as in intermedia. 
Utricularia intermedia appears to have been regarded as 
a rare plant. Trimmer, in his ‘ Flora of Norfolk,’ recorded 
it only from Titchwell, adding Burnham Norton in his 
“ Supplement.” It was noted at Dubeck-in-Thurne by the 
Rev. C. Davie,* and at Stalham and Barton by H. and J. 
Groves, f a total of five Norfolk localities. To these we can 
add five others : Swannington, Roydon, Foulden, Honing 
and East Ruston. In these localities it was extremely 
abundant, and (on those areas) may legitimately be described 
as one of the commonest species. In habit it differs consider- 
ably from vulgaris, which is almost always free-floating, for 
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. From the difference in
