Neocinnamomum (新樟属, xin zhang shu) is a genus of evergreen shrubs or small trees, indigenous to Bhutan, China, India, Indonesia (Sumatra), Myanmar, Nepal, Thailand, and Vietnam.[1][2]

They inhabit montane laurel forests.[3] These trees and shrubs are characteristic of the lower strata of the tropical rainforest but some species are at 20 m tall. They require a warm and wet climate with no extremes of heat and cold.[citation needed] Although there can be months in which there is less rain, no prolonged dry season should occur and rain received on about 150 days per year.[citation needed] Present from rocky and stony ground to waterlogged and marshy areas.[citation needed]

The pollination is by insects[4] that pollinate the very small bisexual[1][2] flowers.[5][6] The inflorescences are highly condensed, with poorly defined branching, their overall shape described as "glomerules".[5] Birds disperse the seeds by avidly eat the fruit[citation needed] which are berry-like drupes.[2] The fruit are ellipsoid or round ("globose").[1] The trees flower in rainy season and the fruits ripen 6 months later.[citation needed] Some species propagate vegetatively too.[2]

N. mekongense is a species that grows in the mountains north of Dali, China. It is popular with butterflies, which possibly are attracted by secretions from extrafloral nectaries.[7]
