Xanthosia is a genus of flowering plants in the family
Description
Plants in the genus Xanthosia are perennial herbs or small shrubs that usually have divided, toothed, or lobed leaves. The flowers are usually arranged in a compound umbel, opposite leaves or on the ends of short, leafy branches, but sometimes reduced to a single flower. Each main branch of the umbel has an involucral bract and each of the secondary umbels ("umbellules") have 2 or 3 bracteoles at the base. The flowers are white, pinkish or pale green with conspicuous, usually egg-shaped, petal-like sepals, the petals narrow and curved inwards. The fruit is a flattened, oblong or round, non-fleshy schizocarp.[2][3][4][5]
