Abstract
A new species of Thismia (Thismiaceae), Thismia jianfenglingensis, is described and illustrated from Hainan Island, China. The new species is similar to T. hongkongensis, displaying a urecolate perianth tube, a loose dome with six perianth lobes, six stamens, and three stigmas. T. jianfenglingensis differs from T. hongkongensis in the color and morphology of perianth tube, the position of outer perianth lobes, the morphology and appendage of connective apex, the morphology of stigmas. The new species is only reported to occur on Hainan Island, China and it is proposed to be Vulnerable (VU) according to the IUCN criteria for the conservation status of plant species due to having a population with a very restricted area of occupancy or number of locations such that it is prone to become critically endangered or even extinct in a very short time period.

Diagnosis:— Thismia jianfenglingensis most closely resembles T. hongkongensis, but differs from it by having the perianth tube darkred and cylindrical-urceolate (not pinkish-white obpyriform-urceolate), the outer perianth lobes are embedded in the dome (not separated from the dome), the connective apex is slightly concave (not bidentate), the lateral appendage of the connective is entire (not trilobed) and the stigma lobe is acute (not rounded).
Etymology:— The specific epithet for this species is related to place of its collection. Jianfengling is the name of the National Nature Reserve in Hainan, China.
