Magnolia

Magnolia Magnolia, referred to as Magnolia, is a deciduous tree of the genus Magnoliaceae (evergreen in South China). The height of the tree is generally 2m or more than 5m. Large flowers leave first and then bloom from March to April, but the flowering period is only about 10 days.

The habits of Magnolia Magnolia

Magnolia is a deciduous tree with a height of up to 25 meters and a diameter of up to 200 centimeters. The crown is narrowly ovoid when young, while mature trees are broadly ovate or loosely ovate. The trunk of the big tree of seed origin is often obvious, the tree body is sturdy, majestic and majestic, the growth is strong, the node long branch is sparse, but the flower quantity is a little sparse. Grafted species often show multi-stem or trunk low-branched characteristics, short branches are dense, the tree is relatively small, but the flowers are colorful, the distant view is flawless and enchanting. Therefore, Magnolia landscapes of different origins have different tastes in the application. In small or closed gardens, grafting species should be used to reflect the interest of antiquity, while real species should be selected in scenic spots to show the rough and simple style.

The bark is gray-white, smooth and less lobed when young, and dark gray and rough when old. Branchlets grayish brown. The terminal buds and pedicels are densely covered with gray-yellow long woolly hairs, such as young rats dormant, and the winter state is more obvious. The branching habit varies with the age of the tree, and the single bud extends when it is young, so the trunk is obvious and the crown is regular. After flowering, the mixed buds of leaf branches extend in two branches or more branches after the ear, and the horizontal development is greater than the growth, so the crown develops in the direction of wide ovate.

Leaf blade alternate sometimes helical, broadly Obovate to Obovate, 10 ~ 18 cm long and 6 ~ 12 cm wide, apex rounded and wide, truncate or slightly concave, with short protruding tip, so it is also called protruding magnolia; attenuate cuneate below middle, entire. Magnolia leaves usually have stipules or appendages at the base, and there are two kinds of stipules, the stipules at the end of the branches are attached to the young stem and separated from the petiole, showing an imbricate shape; the stipules of the leaves are scattered, tile knife-shaped, adhering to both sides of the petiole, the elongated leaves are long, the stipules fall off, and there are annular stipule marks on the young branches, which is the identification characteristic of Magnoliaceae species.

Second, the characteristics of Magnolia and its seeds

Flowers first leaves open, terminal, erect branches, bell-shaped, saucer-shaped when in full bloom, diameters 10 mures 16 cm; perianth 9, occasionally 12 mures 15, or even more than 30, Obovate, jade-white, sometimes reddish at base; filaments purplish red; pistil groups light green, glabrous. The pollen grain is long oval, such as a leaf boat, the equatorial view is olive-shaped, the size is 46.6 to 20 (micron). With a single groove, left and right symmetrical; the outer surface has a fuzzy fine reticulate sculpture, the mesh is small and inconspicuous, and the mesh ridge is blurred.

Aggregate fruit cylindrical, turquoise, turning reddish brown when ripe, 125cm long, 3mm 5cm in diameter, sometimes up to 25cm long and weighing 250g
