Багрянниковые - Cercidiphyllaceae 4/15/17—6/20/21
Cercidiphyllum is a genus containing two species of plants, both commonly called katsura. They are the sole members of the monotypic family Cercidiphyllaceae. The genus is native to Japan and China and unrelated to Cercis (redbuds).
The type species, Cercidiphyllum japonicum, can reach 45 m (148 ft) in height, and is one of the largest hardwoods in Asia. The other species, Cercidiphyllum magnificum, is much smaller, rarely reaching over 10 m (33 ft) in height. Cercidiphyllum produces spurs along its twigs. These are short stems with closely spaced leaves. The foliage is dimorphic. According to a recent description "short shoots bear broadly cordate or reniform, palmately veined leaves with crenate margins; long shoots bear elliptic to broadly ovate leaves with entire or finely serrate margins." Leaf size varies from 3–8 cm long and 3-5.5 cm broad. The genus is dioecious, having separate male and female trees. The small inconspicuous flowers are produced in early spring and wind-pollinated; the fruit is a cluster of 2-4 small pods, each pod 1–2 cm long with numerous small, flattened and winged seeds. The fruits mature in autumn and release their seeds in autumn through winter.
