Euphorbia as a small tree: Euphorbia dendroides. Euphorbia is a large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae.. Euphorbias range from tiny annual plants to large and long-lived trees, [2] with perhaps the tallest being Euphorbia ampliphylla at 30 m (98 ft) or more.
The catkin-like flowers appear in early spring before the leaves. Male and female flowers are borne separately on the same tree . The small 3-lobed capsules or schizocarps split into three equal indehiscent segments (mericarps or cocci) when ripe; on a warm day this splitting can sound like a distant fusillade of shots.
Instant tree shaping [3] [2] [15] is a widely used method. [3] It uses mature trees, perhaps 6–12 ft. (2–3.5 m) long [5] [4]: 196 and 3-4in (7.6–10 cm) in trunk diameter. [5] [4]: 172 An instantaneous form is created by bending, weaving and sometimes cutting or marking the trees into the desired shape. Then the shaping is held in place ...

Xylem is a vascular tissue which moves water and nutrients from the roots to the leaves. Most woody plants form new layers of woody tissue each year, and so increase their stem diameter from year to year, with new wood deposited on the inner side of a vascular cambium layer located immediately beneath the bark.
The tree produces spiky green fruits about the size of a golf ball, which turn brown and drop off the tree over an extended period beginning in fall and continuing over the winter.
Leafy spurge also spreads vegetatively from the root system, which is complex, reported to reach 8 m into the ground and 5 m across, and may have numerous buds. [7] [8] [9] There are two subspecies and a hybrid subspecies: [2] [4] Euphorbia esula subsp. esula. Leaves broadest near apex; umbel bracts 5–15 mm. Throughout the range of the species.
Vernicia fordii (usually known as the tung tree (Chinese: 桐, tóng) and also as the tung-oil or tungoil tree , the kalo nut tree, and the China wood-oil tree) is a species of flowering plant in the spurge family Euphorbiaceae. [2] [3] It is native to southern China, Myanmar, and northern Vietnam. [4]
