Show 444 UTRICULARIA MULTICAULIS. CHAP. XVIII. project straight forward; they are united for a short space at their bases by a 1nem bran e.; and th~y bear a moderate nun1bor of bristles or haus, not s1mple as heretofore ' but sunnounted by glands. Th. e bladd.e rs also differ remarkably from those of the previous species, as within there are no q uadrifid, only bifid, processes. In one bladder there was a minute aquatic larva; in another the remains of some articulate animal; and in 1nost of the1n grains of sand. Utricularia cmrulea (India).- The bladders resemble those of the last species, both in the general character of the antennre and in tho processes within being exclusively bifid. They contained rmnnants of en to1nostracan crustaceans. Utricularia orbiculata (India).-The orbicular leaves and the steins bearing the bladders apparently float in water. The bladders do not differ much fro1n those of the two last species. The antennm, which are united for a short distaneo at their bases, bear on their outer surfaces and summits numerous, long, multieellular hairs surmounted by glands. The processes within the bladders are quadrifid, with the four diverging anns of equal length. The prey w hieh they had captured Qonsistod of ento1nostraean crusta.eeans. Utric1.daria multica1.dis (Sikkim, India, 7000 to 11,000 feet).- The bladders, attached to rhiz01nes, are re1narkable from the structure of the antennte. These are broad, flattened, and of large size; they boar on their margins multicellular hairs, surmounted by glands. Their bases are united into a s~ngle,. rather narrow pedieel, and they thus appear hke a great digitate expansion at one end of. the bladder. Internally the quadrificl processes have divergent arms of equal length. The bladders contained remnants of artieula te ani1nals. CHAP. XVIII. POLYP0l\1PHOLYX. This genus, which is confined to \Vest rn Australia, is eharacterisecl by having a" quadripartite calyx." In other respects, as Prof. Oliver remarks,* "it is quito a U trieularia.'' Polypompholyx rnultifida.-The bladders are attached in whorls round the sum1nits of stiff stalks. The two antennre are represented by a minute membranous fork, the basal part of whieh forms a sort of hood over the orifiee. This hood expands into two wings on each side of the bladder. A third wing or erest appears to be formed by the extension of the dorsal surfaee of the petiole; but the strueture of these three wings eould not be clearly made out, owing to the state of the specimens. The inner surface of tho hood is lined with long simple hairs, eontaining aggregated matter, like that within the quadrifid proeesses of the previously deseribed speeies when in eontaet with deeayed aniInals. These hairs appear therefore to serve as absorbents. A valve was seen, but its strueture eould not be determined. On the eollar round the valve there are in the place of glands numerous one-celled papill£C, having very short footstalks. The quadrifid proeesses have divergent arms of equal length. Remains of entomostraean crustaeeans were found within the bladders. Polypompholyx tenella.-The bladders are smaller than those of the last speeies, but have the same general structure. They were full of debris, apparently organic, but no rmnains of artieulate animals eould be distinguished. * 'Proc. Linn. Soc.' vol. iv. p. 171. |
