Abstract

Thismia jinzun, a new fully mycoheterotrophic species has been discovered from Hainan Province, China. Thismia jinzun is similar to T. javanica and T. tentaculata in overall appearance, but it obviously differs from the latter two species in several characters. Thismia jinzun has 10–12 mm long, gold-yellow tepal appendages (vs 20–30 mm long, orange-white in T. javanica, and ca. 17 mm long, orange-red in T. tentaculata), a gold-yellow floral tube (vs pale orange or pale yellow in T. javanica and white in T. tentaculata), and a gold-yellow annulus (vs orange in T. javanica and bright yellow in T. tentaculata). According to the IUCN criteria, the conservation status of T. jinzun is classified as Critically Endangered (CR).
