Fungi: Their Nature and Uses Sepals 5, united below in an indurated cup, enclosing the utricle. The Manual of the Botany of the Northern United States Including the District East of the Mississippi and North of North Carolina and Tennessee 2012-04-12T02:00:30.140Z The edges join together in the middle part of each fold, and separate from the utricle, the two ends remaining in open connection with its cavity. The Evolution of Man — Volume 2 In animal cells the former is wanting, the membrane representing the utricle. Was Man Created? Pressure of the base of the stapes is exerted on the utricle. Encyclopaedia Britannica, 11th Edition, Volume 9, Slice 7 "Equation" to "Ethics" 2011-02-27T03:00:31.973Z During the development of these organs, the protoplasm of the utricle which contains them offers at first completely normal characteristics, and disappears entirely by degrees as they increase. Fungi: Their Nature and Uses The cells forming all these glands contain a nucleus, and are lined by a thin layer of more or less granular protoplasm, the primordial utricle of Mohl. Insectivorous Plants It is probable, therefore, that the whole utricle is similarly constructed. Insectivorous Plants After 8 hrs. almost all the oblong glands were brown and much more opaque than they were before; their primordial utricles were somewhat shrunk and contained a little aggregated granular matter. Insectivorous Plants The base of the stapes communicates 723 pressures to the utricle.

Fungi: Their Nature and Uses In the third bladder, the quadrifids included distinctly visible granules, and the primordial utricle was a little shrunk after only 8 hrs. Insectivorous Plants Utriculiferous leaf; enlarged about three times. l Upper part of lamina of leaf. b Utricle or bladder. n Neck of utricle. o Orifice. a Spirally wound arms, with their ends broken off. Insectivorous Plants They are absent in the lower part of the utricle where the papillae abound. Insectivorous Plants On the posterior wall of both the saccule and of the utricle there is a ridge, termed in each case the macula acustica, bearing a highly specialized epithelium.

Fungi: Their Nature and Uses Lastly, there is a bundle of spiral vessels which, running up the lower part of the linear leaf, divides close beneath the utricle. Insectivorous Plants Portion of inside of neck leading into the utricle, greatly enlarged, showing the downward pointed bristles, and small quadrifid cells or processes. Insectivorous Plants Most of the oblong glands were now dark brown, but their utricles were not greatly shrunk. Insectivorous Plants After 5 hrs. many of the glands presented a shade of brown, with their utricles slightly shrunk. Insectivorous Plants Its mycelium represents at first strong branched utricles without partitions; the branches are of the higher order, mostly divided into rich and very fine-pointed ramuli. Fungi: Their Nature and Uses A nearly perfect Acarus was found within the utricle or neck of one leaf, but in which of the two was not recorded. Insectivorous Plants The latter include cavities; and as these differ much from the bladders of the foregoing species, it will be convenient to speak of them as utricles. Insectivorous Plants Many of the papillae within both the utricles and necks were discoloured, as if they had absorbed matter. Insectivorous Plants Such creatures would, therefore, perish either within the neck or utricle; and the quadrifid and bifid papillae would absorb matter from their decayed remains. Insectivorous Plants In two of these the quadrifids now appeared full of very finely granular matter, and their protoplasmic lining or primordial utricle was a little shrunk. Insectivorous Plants The primordial utricle or protoplasm lining the processes was also thickened here and there into irregular and variously shaped specks of yellowish translucent matter, as occurred in the case of Utricularia neglecta under similar treatment. Insectivorous Plants The spherical glands were still white, but their utricles were broken up into three or four small hyaline spheres, with an irregularly contracted mass in the middle of the basal part. Insectivorous Plants The utricles of the oblong glands had shrunk very little, but their contents were somewhat aggregated. Insectivorous Plants After six additional hours their primordial utricles were greatly shrunk. Insectivorous Plants In the second specimen, the primordial utricles were considerably shrunk and brownish after 2 hrs. Insectivorous Plants One branch extends up the dorsal and the other up the ventral side of both the utricle and neck. Insectivorous Plants After 23 hrs. all the glands were brown, their primordial utricles greatly shrunk, and in many cases ruptured. Insectivorous Plants Two other summits, with their glands colourless and their utricles not shrunk, were treated with the same solution of urea. Insectivorous Plants If glands which have already become brown, with their primordial utricles shrunk, are irrigated with one of the effective solutions, they are not acted on, or only slightly and slowly.
