What shape, color and shape are the leaves of chrysanthemum?
Today's share: An introduction to the shape, color and appearance of the leaves of chrysanthemum. Here is a detailed introduction to chrysanthemum (scientific name: Dendranthema morifolium Ramat. Tzvelev), in plant taxonomy, is a perennial perennial herb of the genus Compositae and Chrysanthemum.
Perennial herb, 60 - 150 cm high. Stem erect, much branched, with fine hairs or velutinous.
Leaves alternate, ovate to lanceolate, ca. 5 cm long, 3 - 4 cm wide, slightly pinnate, margin coarsely serrate, white velutinous below; petiolate.
The capitulum is born alone at the branch end or leaf axil, 2.5~5 cm in diameter; the involucre is hemispherical, the involucre is 3~4 layers, the outer involucre is green, linear, white velutinous, the margin is membranous; the ligulate flower is white, yellow, reddish or slightly purple, female; the cylindrical flower is yellow, bisexual. Achenes rudimentary. Flowering period is from September to November.
Chrysanthemum is a perennial subshrub with perennial roots. The stem of the propagation seedling is divided into two parts: the aboveground stem and the underground stem. The aboveground stem is 0.2-2 meters high and is highly branched.
Young stems are bright green or brownish in color, covered with gray pilose or villous. Most of the stems die after flowering. In the following spring, evil buds occurred from underground stems.
Chrysanthemum leaves are simple and alternate, with petiole 1-2 cm long, stipules or degenerate on both sides of the stalk, leaves ovate to oblong, with notches and serrations on the margins.
The shape of leaves varies according to the variety, and can be divided into 8 categories: regular leaves, deep regular leaves, long leaves, deep long leaves, round leaves, sunflower leaves, canopy leaves and boat leaves.
The flowers (head) of chrysanthemum are born on the top of the branch, about 2-30 cm in diameter, and the outside of the inflorescence is formed by green segments. There are two forms of flowers on the inflorescences: one is a simply-shaped flower, commonly known as "flower center". The corolla is connected in a simple shape. It is a bisexual flower with a pistil in the center, a 2-lobed stigma, and a chamber in the lower position of the ovary, surrounding the flower. The main medicinal stamens are gathered; the other is a lingual flower, which is born on the edge of the inflorescences, commonly known as "petals."
The stamens in the flower degenerate, with 1 pistil. The ligulate flowers are large and colorful, and are divided into five types: flat, spoon, tube, cinnamon, and abnormal. Achenes (commonly called "seeds") are 1-3 mm long and 0.9-1.2 mm wide. The upper end is slightly pointed, in a flat wedge shape, with longitudinal ribs on the surface, and brown. There is a seed without endosperm in the fruit. The fruit matures in January to February of the following year, and the 1000-grain weight is about 1 gram.
[Summary] The shape of chrysanthemum leaves varies according to the variety. They can be divided into 8 categories: regular leaves, deep regular leaves, long leaves, deep long leaves, round leaves, sunflower leaves, canopy leaves and boat leaves. The leaves of chrysanthemum are opposite, with short stems, ovate to lanceolate shapes, and pinnately lobed or cleft. The leaves of chrysanthemum are ovate, opposite, feather-like, and are green in color, 5-15 cm long and 3-6 cm wide.
