These fruits, which are as large as the head of a child, often twelve or thirteen inches in diameter, make a very loud noise in falling from the tops of the trees. In our climates only the cucurbitaceae produce in the space of a few months fruits of an extraordinary size; but these fruits are pulpy and succulent.
CUCURBITACEAE. Homologous nature of the tendrils Echinocystis lobata, remarkable movements of the tendrils to avoid seizing the terminal shoot Tendrils not excited by contact with another tendril or by drops of water Undulatory movement of the extremity of the tendril Hanburya, adherent discs VITACAE Gradation between the flower-peduncles and tendrils of the vine Tendrils of the Virginian Creeper turn from the light, and, after contact, develop adhesive discs SAPINDACEAE PASSIFLORACEAE Passiflora gracilis Rapid revolving movement and sensitiveness of the tendrils Not sensitive to the contact of other tendrils or of drops of water Spiral contraction of tendrils Summary on the nature and action of tendrils.
Tendril-bearers have undergone much more modification than leaf-climbers; hence it is not surprising that their supposed primordial habits of revolving and twining have been more frequently lost or modified than in the case of leaf-climbers. The three great tendril-bearing families in which this loss has occurred in the most marked manner, are the Cucurbitaceae, Passifloraceae, and Vitaceae.
Swiggs's ears with such learned terms as "Boraginiae," "Cucurbitaceae," "Leguminosae," and as winter drew in, master and man would hold long consultations indoors over certain plants, the portraits of which in the herbals seemed familiar enough, though their habitats often proved, on further reading, to lie no nearer than Arabia Felix or the Spice Islands.
In this respect they differ from all those previously described, with the exception, perhaps, of the Cucurbitaceae. The homological nature, however, of a tendril seems to make no difference in its action. Vitis vinifera. The tendril is thick and of great length; one from a vine growing out of doors and not vigorously, was 16 inches long.
The plant to which I at present refer is one of the cucurbitaceae, which bears a small, scarlet-colored, eatable cucumber. Another plant, named Leroshua, is a blessing to the inhabitants of the Desert.
The word cucumis used in the original of this passage embraces many of the cucurbitaceae, but the context shows that here means the cucumber. The physical revolutions thus wrought by man have not indeed all been destructive to human interests, and the heaviest blows he has inflicted upon nature have not been wholly without their compensations.
CUCURBITACEAE. The tendrils in this family have been ranked by competent judges as modified leaves, stipules, or branches; or as partly a leaf and partly a branch. De Candolle believes that the tendrils differ in their homological nature in two of the tribes. From facts recently adduced, Mr.
It is a singular fact that three families, so widely distinct as the Bignoniaceae, Vitaceae, and Cucurbitaceae, should possess species with tendrils having this remarkable power. Sachs attributes all the movements of tendrils to rapid growth on the side opposite to that which becomes concave.
The species to be described belong to ten families, and will be given in the following order: Bignoniaceae, Polemoniaceae, Leguminosae, Compositae, Smilaceae, Fumariaceae, Cucurbitaceae, Vitaceae, Sapindaceae, Passifloraceae. BIGNONIACEAE. This family contains many tendril-bearers, some twiners, and some root-climbers. The tendrils always consist of modified leaves.
