Alangium salviifolium.

Alangium is a small genus of flowering plants. The genus is treated either in a broad view of the dogwood family Cornaceae, or as the sole member of its own family Alangiaceae.

[edit] Characteristics

Differences from the other genera in Cornaceae include articulated pedicels, subulate bracts, bitegmic seeds and the single-seeded fruit. The entire or lobed leaves are alternate. The bisexual (rarely unisexual) nectiferous flowers are arranged in axillary cymes. The flowers have 4-10 small sepals and 4-10 linear petals. There are 4-40 stamens distributed in a single cycle. The ovary is bilocular (sometimes unilocular), while the fruit is drupe.

[edit] Species

The genus consists of 17 species of small trees, shrubs and lianas, and is native to western Africa, Madagascar, southern and eastern Asia (China, Malaysia, Indonesia, and the Philippines), tropical Australia, the western Pacific Ocean islands, and New Caledonia.

One species, Alangium chinense (Chinese: 八角枫; pinyin: bā jiǎo fēng), is considered one of the fifty fundamental herbs in traditional Chinese medicine.
