in thickness, but are always somewhat compressed. At an 
early stage of growth, the flat or ventral surface faces the 
axis or stem; but the footstalks must have some power of 
movement; for in plants kept in my greenhouse the ventral 
surface was generally turned either straight or obliquely 
downwards. The Rev. H. M. Wilkinson examined plants for 
me in a state of nature, and found this commonly to be the 
case, but the younger bladders often had their valves turned 
upwards. 
The general appearance of a bladder viewed laterally, with 
the appendages on the near side alone represented, is shown 
on the preceding page (fig. 18). The lower side, where 
the footstalk arises, is nearly straight, and I have called it

the ventral surface. The other or dorsal surface is convex, 
and terminates in two long prolongations, formed of several 
rows of cells, containing chlorophyll, and bearing, chiefly on 
the outside, six or seven long, pointed, multicellular bristles. 
These prolongations of the bladder may be conveniently 
called the antenne, for the whole bladder (sce fig. 17) 
curiously resembles an entomostracan crustacean, the short 
footstalk representing the tail. In fig. 18, the near antenna 
alone is shown. Beneath the two antenne the end of the 
bladder is slightly truncated, and here is situated the most 
important part of the whole structure, namely the entrance 
and valve. On each side of the entrance from three to rarely 
seven long, multicellular bristles project outwards; but only
