It is severely threatened by habitat disturbance and degradation. The forested ridge lies outside the network of Totally Protected Areas and is surrounded by oil palm plantations. The Bukit Tukau area has been logged and is currently the site of an active quarry. The area is being considered as an extension to the Gunung Ledang State Park to protect the Critically Endangered

It is a rare species known only from about four small populations, each with a few to about 60 fertile plants. From the many seedlings, it is apparently regenerating freely from seed. Plants with flowers and fruits were collected in July and December but in March and October only fruiting plants with abundant fruit were found. In March 2016 after a drought, its leaves were completely wilted and dried. It is not known if these plants can recover or whether the population will regenerate from seed. The woody stem shows that they are perennial plants.</paragraph>

However, very few flowers from the Bukit Tukau population were available to study variation in this population. Indeed, further investigation of the two populations may result in the recognition of two separate taxa, perhaps at an infraspecific rank.
