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.
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.
One particular tree of the genus Hevea, more commonly known as the rubber tree, is probably the most famous hydrocarbon plant, supplying an estimated one third of the world’s rubber demand. It is still not as quick and cheap to make as petroleum-based rubber, which is why it does not occupy a larger portion of the market. [ 2 ]
Croton trees play an important role in local ecosystems for shade, wind protection, and soil conservation. [4] The wood from the trees makes good fuelwood and charcoal. The wood is also known for its termite resistance and is used for fence posts and poles in construction. Given their high nitrogen content, the leaves are often used for mulch.
Trees in this genus are either deciduous or evergreen. Certain species, namely H. benthamiana , H. brasiliensis and H. microphylla , bear "winter shoots", stubby side shoots with short internodes, scale leaves on the stem and larger leaves near the tip; on these, the leaves are shed leaving the tree bare before new shoots develop.

Two trees may grow to their mature size adjacent to each other and seemingly grow together or conjoin, demonstrating inosculation. These may be of the same species or even of different genera or families, depending on whether the two trees have become truly grafted together (once the cambium of two trees touches, they self-graft and grow together).
