| 例句 | The name, Dionaea muscipula, is derived from words meaning “the goddess of love” and “mousetrap,” according to the conservancy. Venus Flytraps Need Protection From Poachers in North Carolina 2016-11-28T05:00:00Z And Queen Dionaea's head bounced down the stairway into her garden of live oaks. Daughter of the Night On your own Earth there are, we learn, hundreds of varieties of insectivorous plants: the Venus fly-trap, known otherwise as the Dionaea Muscipula, which has a leaf hinged in the median line, with teeth-like bristles. Astounding Stories of Super-Science September 1930 We do not hesitate to class amongst vegetables the Drosera, the Dionaea, the Pinguicula, which are insectivorous plants. Creative Evolution What purpose has the long spur in the flower of Angraecum, or the marvellous bucket of Coryanthes, the flytrap of Dionaea, the pitcher of Nepenthes? Creation and Its Records These observations were made subsequently to those on Drosera, Dionaea, Drosophyllum, and Pinguicula; so that I was familiar with the appearance of these substances when undergoing the early and final stages of digestion. Insectivorous Plants And so, he glided rapidly down from the trunk of his favorite tree and emerged into the paths of the garden just as Dionaea's bleeding head rolled out from the base of the steps. Daughter of the Night The flexible and sensitive filament of Dionaea likewise transmits a stimulus, without itself bending; as does the stem of Mimosa. The Power of Movement in Plants The result is much the same to the insect, whether captured in the trap of Dionaea or stuck fast to the limed bristles of Drosera. Darwiniana; Essays and Reviews Pertaining to Darwinism Perhaps the nearest analogy may be found in such plants as Drosera and Dionaea; for here animal matter is digested and converted into peptone not within a stomach, but on the surfaces of the leaves. The formation of vegetable mould through the action of worms, with observations on their habits In this respect Dionaea differs from Drosera, which catches and digests many insects after shorter intervals of time. Insectivorous Plants Dionaea was a very evil sorceress, and Druga, most heroic of men, had long sought to bring her into his power, and to end her evil days. Daughter of the Night Nor could we see any in Dionaea, though the plants were not so carefully observed. The Power of Movement in Plants One such species, D. filiformis, the thread-leaved sundew, is not uncommon in this country, both north and south of the district that Dionaea locally inhabits. Darwiniana; Essays and Reviews Pertaining to Darwinism It is an endless subject, and I must cut it short, and for this reason shall not do much on Dionaea. Life and Letters of Charles Darwin — Volume 2 I will, however, append a few remarks on the differences between this plant and Dionaea. Insectivorous Plants Druga related to Eos all the events that had transpired since the lopping off of Dionaea's head. Daughter of the Night These oscillations were exactly like those described under Brassica and Dionaea, but they occurred only occasionally. The Power of Movement in Plants While Dionaea is as local in habitation as it is singular in structure and habits, the Droseras or sundews are widely diffused over the world and numerous in species. Darwiniana; Essays and Reviews Pertaining to Darwinism It is really beautiful how quickly and well Drosera and Dionaea dissolve little cubes of albumen and gelatine. Life and Letters of Charles Darwin — Volume 2 The outside of the leaves and the petioles are covered with minute two-armed papillae, evidently answering to the eight-rayed papillae of Dionaea. Insectivorous Plants Druga and Eos descended by the ladder of ruby glass, and went side by side through the garden and Druga took the stairs he knew well up to the sleeping chamber of Dionaea. Daughter of the Night Dionaea muscipula: circumnutation of a young and expanding leaf, traced on a horizontal glass in darkness, from noon Sept. 24th to 10 A.M. 25th. The Power of Movement in Plants Only a brief chapter is devoted to Dionaea of North Carolina, the Venus's fly-trap, albeit, "from the rapidity and force of its movements, one of the most wonderful in the world." Darwiniana; Essays and Reviews Pertaining to Darwinism It is an aquatic Dionaea, which has acquired some structures identical with those of Utricularia! Life and Letters of Charles Darwin — Volume 2 This is certainly the case with Drosera, Drosophyllum, and Dionaea; almost certainly with Aldrovanda; and, from analogy, very probable with Roridula and Byblis. Insectivorous Plants The sleepy-eyed Dionaea poked her head above the covers at the sound of their entry. Daughter of the Night The whole hypocotyl of a cabbage or the whole leaf of a Dionaea could not jerk forwards unless a very large number of cells on one side were simultaneously affected. The Power of Movement in Plants After a time the flowing golden bands of Life-energy entered, focusing subtly all about her, so that she seemed to Dionaea truly to be the Mother of All, and the greatest of All Goddesses anywhere. Daughter of the Night For even a serpent has been known to swallow its tail, and Dionaea had no desire to know if Baena could do that trick. Daughter of the Night In Dionaea the whole lobe, with the exception of the marginal prolongations or spikes, curves inwards, though the chief seat of movement is near the midrib. Insectivorous Plants A great laugh broke from him to see the reptilian change the grafting had wrought in Dionaea's beauty. Daughter of the Night The oscillatory and jerking movements of the leaves of Dionaea, which resemble those of the hypocotyl of the cabbage, are highly remarkable, as seen under the microscope. The Power of Movement in Plants Eos, sitting quietly and watching the bound serpent, smiled at this continual by-play, and offered to release Dionaea for revealing her knowledge of Diana, so that some chink in her armor might be found. Daughter of the Night Came that day which was the time appointed by Diana Triformis for her visit to Dionaea. Daughter of the Night These experiments are sufficient to show that the secretion from the glands of Dionaea dissolves albumen, gelatine, and meat, if too large pieces are not given. Insectivorous Plants Dionaea did not say anything, but Baena coiled swiftly on the bed and struck out full length, his fangs meeting in Druga's arm. Daughter of the Night Similar results were observed with Dionaea and Pinguicula. The Power of Movement in Plants This snake she quickly separated from its head, and placed upon its cunning female body the head of Dionaea, doing all that was needful successfully to incorporate the two into one life. Daughter of the Night So conversing, the now lowly Dionaea and the now lordly Baena glided from the chamber and made their way down the ruby ladder of strange crystal, and out into the world. Daughter of the Night With respect to the functions of the several parts, there can be little doubt that the long jointed hairs are sensitive, like those of Dionaea, and that, when touched, they cause the lobes to close. Insectivorous Plants Druga wrapped the great body around and around his body and arm, seizing the neck of Dionaea in one hand and the neck of Baena in the other. Daughter of the Night The still closed lobes of a young leaf of Dionaea projected at right angles to the petiole, and were in the act of slowly rising. The Power of Movement in Plants He lay there all night, waiting for his own life's blood to reanimate the mind of Dionaea. Daughter of the Night Day and night Dionaea plotted, and in her mind a fitting revenge grew—it would include the lovely Feronia, Druga's beloved.... Daughter of the Night Its upper surface is studded with colourless glands like, but more simple than, those of Dionaea; they are supported on distinct footstalks, consisting of two rows of cells. Insectivorous Plants Listen to me, Dionaea, the best thing you can do for yourself is to try to win the favor of Eos. Daughter of the Night In all these respects the filaments of Dionaea behave exactly like the tentacles of Drosera. Insectivorous Plants Canby, of Wilmington, to whom I am much indebted for information regarding Dionaea in its native home, has published in the 'Gardener's Monthly,' Philadelphia, August 1868, some interesting observations. Insectivorous Plants On the other hand, with Dionaea, touching the filaments excites incomparably quicker movement than the absorption of animal matter by the glands. Insectivorous Plants There is a great contrast between Drosera and Dionaea in the effects produced by mechanical irritation on the one hand, and the absorption of animal matter on the other. Insectivorous Plants Dionaea, I think too you should seize this opportunity to get out of this fix we are in. Daughter of the Night We have seen that boiling water in like manner causes the tentacles of Drosera to curve backwards; and this is an analogous movement to the divergence of the lobes of Dionaea. Insectivorous Plants We shall hereafter see that the filaments on the leaves of Dionaea are likewise insensible to the impact of fluids, though exquisitely sensitive to momentary touches from any solid body. Insectivorous Plants We shall hereafter see that the purple fluid within the sensitive filaments of Dionaea, which do not secrete, likewise undergoes aggregation from the action of a weak solution of carbonate of ammonia. Insectivorous Plants Nevertheless, if little bits of damp albumen or fibrin are placed on these sessile glands, they begin after a time to secrete, in the same manner as do the glands of Dionaea when similarly treated. Insectivorous Plants That Dionaea was considering his words was evident. Daughter of the Night The sensitive organs of Drosera and Dionaea are also specialised, so as not to be uselessly affected by the weight or impact of drops of rain, or by blasts of air. Insectivorous Plants The rate at which the motor impulse is transmitted, though rapid in Dionaea, is much slower than in most or all animals. Insectivorous Plants They differ also from the six sensitive filaments of Dionaea in being colourless, and in having a medial as well as a basal articulation. Insectivorous Plants They are, therefore, homologous with the sessile glands hereafter to be described on the leaves of Dionaea and Drosophyllum. Insectivorous Plants Feronia gazed at them with her stone eyes, and all the men gazed at Feronia as if transfixed by her stony beauty, and the sight made Dionaea shiver with apprehension. Daughter of the Night That these glands secrete a fluid which dissolves or digests animal matter out of the bodies of the creatures which the leaves capture, is also highly probable from the analogy of Dionaea. Insectivorous Plants It is a strange fact that Dionaea, which is one of the most beautifully adapted plants in the vegetable kingdom, should apparently be on the high-road to extinction. Insectivorous Plants Dionaea includes only a single species, which is confined to one district in Carolina. Insectivorous Plants |
