Opposite some of these leaves springs a tendril, by aid of which the plant climbs.
Labrusca there is a tendril opposite to each leaf, so that the podium bears only a single leaf.
They range from subjects of the homeliest and most mirthful realism to others serious and devout, and from literal or almost literal transcripts of natural form to the most whimsically abstract combinations of linear pattern and tendril .and flourish.
Metamorphosis.It has already been pointed out that each kind of member of the body may present a variety of forms. For example, a stem may be a tree-trunk, or a twining stem, or a tendril, or a thorn, or a creeping rhizome, or a tuber; a leaf may be a green foliage-leaf, or a scale protecting a bud, or a tendril, or a pitcher, or a floral leaf, either sepal, petal, stamen or carpel (sporophyll); a root may be a fibrous root, or a swollen tap-root like that of the beet or the turnip. All these various forms are organs discharging some special function, and are examples of what Wolff called modification, and Goethe metamorphosis.
Each podium consists of a portion of the stem bearing one or more leaves, each with an axillary bud or buds, and terminating in a tendril or an inflorescence.
This new podium, now in a direct line with its predecessor, produces leaves and ends in its turn in a tendril or inflorescence.
Other authorities explain the formation of the tendril and its anomalous position opposite to a leaf by supposing that the end of the stem bifurcates during growth, one division forming the shoot, the other the tendril or inflorescence.
In Lathyrus Aphaca and some other plants the true pinnate leaves are abortive, the petiole forms a tendril, and the stipules alone are developed, perform ing the office of leaves.
When a sensitive tendril comes into contact with a foreign body, its growth becomes so modified that it twines round it.
They are bulbous plants, the slender stems of which support themselves by tendril-like prolongations of the tips of some of the narrow generally lanceolate leaves.
The peduncle occasionally becomes abortive, and in place of bearing a flower, is transformed into a tendril; at other times it is hollowed at the apex, so as apparently to form the lower part of the outer whorl of floral leaves as in Eschscholtzia.
Since the 13th century the snake, under Gothic influence, developed into a boldly designed tendril set with leaves, which usually encircled a figure or group of figures, and the knob dividing shaft and crook into an elegant chapel (6 and 7).
The inflorescence is of a cymose character, the terminal branch being represented by the tendril, the side branches by flower-stalks, or the inflorescence may be reduced to a single stalk.
Gloriosa, well known in cultivation, climbs by means of its tendril-like leaftips; it has handsome flowers with decurved orange-red or yellow petals; it is a native of tropical Asia and Africa.
Foliage, tendril and inflorescence, reduced.
While the tendril is thus diverted from its original direct course, the axillary bud of the leaf opposite the tendril begins a new podium, by lengthening into a shoot which assumes the direction the tendril had prior to its deflexion.
There are numerous transitional states between the ordinary form of tendril and the inflorescence.
The tendril or inflorescence, according to the views above explained, though in reality terminal, is bent to one side; hence it appears to be lateral and opposite to the leaf.
