Thismia neptunis

Thismia neptunis is a species of Thismia endemic to Borneo. It was discovered by Italian botanist Odoardo Beccari in 1866, and described in 1878. It was not observed again until 2017, when it was first photographed by a team of biologists from the Czech Republic. It was found in the Gunung Matang massif in western Sarawak, in the Malaysian part of the island of Borneo.

T. neptunis lives underground, and is a myco-heterotroph, a plant which obtains nutrients through a parasitic relationship with fungi. It does not bloom every year, and when it does, its flower appears above the soil for only a few weeks.
