Dendrobium drumstick: It grows on the trunk of sunny evergreen broad-leaved forest or rocks under sparse forest at an altitude of 520 ~ 1620 meters, and is distributed in northeast India, Myanmar, Thailand, Laos and Vietnam.

Dendrobium candidum: named after its iron-green skin. It is a perennial epiphytic herb of Orchidaceae. I like semi-humid rocks and virgin forests with humidity as high as tree trunks, warm and humid climate, semi-cloudy and semi-sunny, and not cold-resistant.
