Rehdera

Rehdera is a genus of flowering plants in the family Cornaceae, sometimes referred to as the dogwood family. It is closely related to the Cornus genus (true dogwoods) but differs in certain floral and fruit characteristics. The most well-known and typically only member of this genus is Rehdera sinensis.

Rehdera sinensis (Chinese Rehdera) is a deciduous tree native to central and western China. It is known for its late flowering, typically occurring in late summer, which is unusual for dogwoods. The flowers are small, white, and inconspicuous, arranged in panicles. The bracts associated with the flowers, which are the showy part in many Cornus species, are reduced or absent in Rehdera.

The fruit is a drupe, similar to other dogwoods. The leaves are opposite, simple, and ovate to elliptical in shape. Rehdera sinensis is grown as an ornamental tree, prized for its late-season flowering interest and elegant form. It prefers well-drained soil and a sunny or partially shaded location.

The taxonomic placement of Rehdera has been debated, with some botanists previously classifying it within Cornus. However, molecular and morphological evidence supports its recognition as a distinct genus.
