État de la populationExpert
This is noted to be a rare species (Jonker 1948). Mycoheterotrophs are often difficult to locate, as they are frequently small and hidden within leaf litter in shady forests. Flowering season may be short and unpredictable which adds to the difficulty in locating and collecting these species (Merckx 2013). It is not possible to know whether the lack of collection reflects a very small population or difficulty in locating this species and the population trend is uncertain. However, it suspected that, as there have been notable declines in forest habitats within its range which are still ongoing, that the population trend will be decreasing.

Description complète des menacesExpert
There has been a large reduction in forest cover within the range of this species with logging and clearing for plantations being particular threats (Mohd-Azlan and Lawes 2011). For example, the acreage under oil palm in Malaysia increased from one million hectares in 1980 to five million in 2012 (Malaysian Palm Oil Board 2015). There has also been an increased frequency in fires within the region (WWF 2015). These general threats to forests are likely to impact on this species but any specific threats are unknown.

Mesures de conservation recommandéesExpert
A collection was made in Gunung Mulu National Park in 1978 and two other collection points (from 1866 and 1954) were possibly from within what is now the Kubah National Park, Sarawak. No specific conservation actions are known and much further research is needed.
