Aside from the type collection of this species, made over 100 years ago, no collections have been made, nor observation recorded. Due to a deficiency in information regarding the distribution of this species, as well as information regarding its habitat preferences and potential threats, this species is listed as DD until such information arises from research.
Why suggested for a Global Red List Assessment?
The only known record of this species appear to be its type specimen, which was collected at Negros Island, Philippines, at an altitude of 2000m, pre-19113. This specimen is currently registered in the Herbarium of the Swedish Museum of Natural History (geographic data is provided by gbif, citation needed).
Population and Trends
The current status of this species’ population is uncertain at this time, and its trends cannot be confirmed without further research.
Population Trend: Uncertain
Habitat and Ecology
Precise information on the habitat type of this species is deficient, however given its named locality and altitude, it is reasonable to assume that this species was found within the tropical montane forests of Mount Canlaon.
Subtropical/Tropical Moist Montane Forest
If wild populations of this species do exist within its known locality, they could be threatened by volcanic eruption.
At this time, no conservation action can be recommended without further research to confirm existence of this species in the wild.
Much further research is required in order to confirm the existence of any wild populations of this species at its last known locality, as well as to assess the threat of volcanic eruption and any other threats which might be affecting this species.
