The species was first discovered in a ravine of Tai Mo Shan in 1955 and only one individual was found at that time. Since then, a few more wild populations were found in Ma On Shan and also in Guangdong. In Hong Kong, the localities of its occurrence are in Country Parks under protection. The species is protected under the Forestry Regulations (Cap. 96 sub. leg.). AFCD have been actively propagating this plant and reintroducing it to the wild. Ex-situ conservation has also been adopted and living specimens are displayed in the Shing Mun Arboretum.
