Description of the morphological characteristics and main habits of Chinese orchids
Dwarf species means that their adult plant form is much shorter than their original species, but the leaves are not necessarily narrower than the original species, or even wider. The odd-leafed species, on the other hand, have produced an alienated form than the original species, even deviating from their original shape, and are also dwarfed compared to the original species. As a result, often dwarf species are also characterized by both odd-leafedness.
Dwarf species can not be measured by a fixed yardstick, due to seedlings or environmental discomfort caused by weak plants and normal plants in the height of a considerable distance, can only be recognized in its performance morphology. Its main performance in the leaf blade short thick, broad leaf width, petiole short strong, leaf tip rounded, especially the leaf pants (leaf a) tip rounded tightly for the "treasures".
Leaf shape dwarf species generally in the form of the whole leaf has three specific conditions: (1) the tip of the leaf suddenly contracted for the shape of the smooth tip, flat or tightened into a small tail tip to the back of the leaf barbs. Most leaves have a rounded fingertip-like tip. (2) leaf width is wide, its widest place for the lower 1/3 of the leaf tip, the general width and leaf length ratio of 4:1 to 9:1. because short or short is relative, and the ratio of leaf length and width is a better description of the shape of the short species of leaf. (3) The overall shape of the leaf is in the shape of a dragon boat belly or fusiform, or even "spoon" shape. It is especially important that the later leaves have this shape.
Leaf thickness dwarf species of leaves are thick leathery. The appearance of leaf thickness, thicker than the average leaf 1 to 2 times thicker. Some of the dwarf species leaves are more "hard", encountered in hot and dry weather is not easy to lose water and produce dehydration. That is, some of the short seed leaf shape and leaf thin "short seed" in the quality of the discount.
A shape "A" refers to commonly known as the leaf pants, is a major reference trait to determine whether an orchid is a dwarf species. It is generally accepted that the leaf armor of a dwarf species must be short and bluntly pointed. The distance between the nails is small, and they are compact with each other, with little difference in size, and all the leaf nails are tightly embracing the petiole, and the tips of the nails and the petiole are close to each other. Some dwarf species of leaf armor outwardly forked and leaf blade separation, in the quality of the poorer. And the leaf blade with dwarf species leaf blade form, but the tip of the leaf armor is long and outside, may be "gunboat", when the new shoots, the leaf blade will produce a non-dwarf species of the normal shape. The shape of the leaf armor also has a certain correlation with the floral art. Therefore, the short rounded petiole of the dwarf species must be matched with the short blunt leaf blade, in order to control the shape of the whole plant.
The petiole of dwarf species is short and wide, commonly known as short feet. Generally its "finger ring" (leaf blade and petiole joint) does not reveal the leaf armor, so as to appear the whole plant short and strong.
Odd leaf type is often associated with dwarf species. Dwarf species have many varieties of leaf shape of the performance of the "strange", of course, there are also many odd-leafed species have some characteristics of the dwarf species, and the plant is quite "tall". In short, the leaf shape of the odd-leafed species and the normal form of the original species in the height, arrangement and straight curvature of the differences, specifically the following cases:
Wrinkles refers to the surface of the leaf is not smooth and undulating, with a rather rough intuitive feeling. Wrinkles of the undulation is not the bottom of the leaf blade and the surface of the parallel undulation, but by the leaf blade of the fence organization is not arranged neatly and some of the cells upward raised arrangement of the leaf surface high and low undulation, the formation of a "mound" shaped protrusion, commonly known as "clam film skin", such as "Cilong", "Longmei" and so on. Wrinkles have a variety of forms, some of the fine and young close uniform, some of the grain thick and deep such as the undulation of dragon scales, very "texture" sense. Wrinkles in the front of the leaf blade is more prominent.
The shape of the leaf blade of the high dipper is like the "melon dipper" which is used in scooping up water in daily life and it is called "melon dipper". This kind of leaf blade petiole is longer, and the lower part of the leaf blade is narrower, but from the "finger ring" at the tip of the leaf gradually increase, to the front end of the leaf near the most inflated, and then suddenly tighten the end of the formation of a blunt circle. The leaf armor of this odd leaf type is also longer but more bluntly rounded. With a head-heavy feeling, and rich in art.
Crystalline body crystal is the main factor that causes the odd leaf species. It does not contain chlorophyll or other pigments in the leaf tissue, but is transparent like a crystal mine and so named. It is unevenly distributed in leaf veins, leaf fenestration tissue or leaf barrels. It is especially abundant in the petiole. Its presence creates an uneven growth of the leaf blade, resulting in wrinkles, undulations, twists, and wrinkles that create an odd leaf shape. Although the leaf blade is pointed and the leaf armor is pointed and long, the crystal body grows at the base of the leaf and restricts the growth of the leaf blade, so the plants containing the crystal body are shorter, such as the "Words of the Dragon" (a new variety). The crystals are sometimes distributed in a "linear" shape, resulting in longitudinal folding of the leaves. Such as "Anlong" (new variety). However, the crystals are distributed in the collar of the leaf blade and form the "crystal collar".
The mechanism of "crystal body" in the orchid plant is not clear.
Gnarled This is caused by the longitudinal "traveling dragon" of the leaf blade. The growth of the leaf tissue is not uniform in the longitudinal direction of the leaf blade, and the "rows of dragons" make the leaf blade grow in a serious twist, and the overall arrangement of the leaf blade produces a "disordered" and disorganized feeling. This is a non-equilibrium artistic composition, with a considerable sense of dynamism and force. For example, "Wenshan Jialong" is a representative work of this type of strange leaves. Most of these odd-leafed varieties have the characteristics of dwarf species in terms of leaf blade and leaf armor.
There are still many types of dwarf qiye class in the categorization of morphology. However, when we look at the overall combination of orchids, we have to consider the superposition of shapes between them or cover them, of course, all the features are concentrated in one plant that is the "ideal" or "perfect", and the source of the art of appreciation of the dwarf species of qifengs is also derived from this.
