Insectivorous plants . cially onvery young bladders, which have an elliptical insteadof a circular outline. The tw^o terminal cells aretransparent, but must hold much matter in solution,judging from the quantity coagulated by prolongedimmersion in alcohol or ether. * I infer that this is the case om Lentibiilariacese, from the from a drawing of a seedling Videnskabelige Meddelelser, given by Dr. Warming in his Copenhagen, 1874, Nos. 3-7, pp. paper, Bidi-ag til Kundskaben 33-58. 398 UTEICULARIA NEGLECTA. Chap. XVIL The bladders are filled with water. They generally,but by no means always, contain bubbles of air. Ac-cording to the quantity of the contained water andair, they vary much in thickness, but are always some-what compressed. At an early stage of growth, theflat or ventral surface faces the axis or stem; but thefootstalks must have some power of movement; forin plants kept in my greenhouse the ventral surfacewas generally turned either straight or obliquelydownwards. The Kev. H. M. Wilkinson examined. Fig. is. ( Utricularia neglecta.) Bladder; much enlarged, c, collar indistinctly seen through the walls. plants for me in a state of nature, and found thiscommonly to be the case, but the younger bladdersoften had their valves turned upwards. The general appearance of a bladder viewed late-rally, with the appendages on the near side alonerepresented, is sho^vn in the accompanying figure(fig. 18). The lower side, where the footstalk arises, isnearly straight, and I have called it the ventral surface.The other or dorsal surface is convex, and •terminatesin two long prolongations, formed of several rows ofcells, containing chlorophyll, and bearing, chiefly on Chap.

These prolongations of the Madder may beconveniently called the antenna, for the whole bladder(see fig. 17) curiously resembles an entomostracan crus-tacean, the short footstalk representing the tail.
