The alias of Castanopsis carlesii is also called Little Red Castanopsis carlesii, Little Leaflet Castanopsis carlesii, Fine Rice Round, Castanopsis carlesii, White Cone, Castanopsis carlesii, Red Chestnut, Kemu, Cottonwood, Rice Cone, Rice Round, Southwest Castanopsis carlesii, Fine Leaf Chestnut, White Cone.
It is distributed inland, such as Hubei, Sichuan, Guizhou and other places, that is, the thorns of the shell bucket grow longer as they are farther away from the coast. The outer wall of the shell bucket has only warty bodies to short spines, and the continuous phenomenon is quite obvious.

Extended data
Main varieties of Castanopsis carlesii
The difference between Castanopsis carlesii (variety) and Castanopsis carlesii is that the spines in the shell bucket are 2-5 mm long, and the spines at the base often combine to form spines, and the spines at the top of the shell bucket are dense and long. The flowering and fruiting periods are the same as before. The bark is smooth, and the bud scales under the branches are obvious. The wood is usually light yellow or yellow-white, which is called white cone, white citron or white Castanopsis, but the wood of old trees is yellow-brown, so it is also called yellow citron.
There are two kinds of thin and wide wood rays in xylem. The broad wood rays are very narrow, the annual rings are slightly obvious, not round, the material is slightly solid, the structure is slightly thick, and it often cracks after drying. The wood properties are far inferior to those of red cones, and it is generally classified as white cones, which is a common main tree species south of the Yangtze River. Sichuan (Emei, Qingcheng Mountain) and Guizhou (Fanjing Mountain, Tiantai Mountain and other places). Born in mountainous mixed forest at higher altitude, sometimes it becomes a small piece of pure forest.
