Ac- cording to the quantity of the contained water and air, they vary much in thickness, but are always some- what 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 general appearance of a bladder viewed late- rally, with the appendages on the near side alone represented, is shown in the accompanying figure (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 nelk, contaiaing chlorophyll, and bearing, chiefly on.
