What is Euonymus chibae
Euonymus chibae , Hizen mayumi (scientific name: Euonymus chibae) is a subtropical small evergreen evergreen tree of the family Celastraceae, native to Shikoku, Kyushu, Okinawa (Japan), and the Korean Peninsula. It grows naturally in coastal forests in warm regions. It is 4 to 12 meters tall. The young branches are green and 4-ribbed. The leaves are green, oblong-ovate, 5-10 cm long, 2-5 cm wide, serrate on the upper half, and arranged in opposite pairs. 2-7 small yellow-green flowers are produced from the leaf axils in concentrated inflorescences from April to June. The stamens are four in number and are attached to the top of the flower disk. The flowers are followed by an orange capsule with a four-lobed, angular, 1 cm-diameter, inverted-oval-shaped capsule. The botanical name "hizen-mayumi" was given by Dr. Tomitaro Makino, a member of the Mayumi genus, because it was first discovered in Isahaya City, Nagasaki Prefecture, in the western part of the country formerly known as Hizen. The species name "chibae" is named after Mr. Chiba Tsunezaburo, who collected the species.
According to research conducted by Tokushima Bunri University, the fruit is believed to be effective in inhibiting the growth of cancer cells. It is listed as an endangered species in the Red Data Book of the Ministry of the Environment.
