The Cinnamon Sun-orchid is a terrestrial orchid growing to 40 cm high. Its golden yellow flowers have a strong cinnamon odour (Brown et al. 1998; Phillimore et al. 1999).
This species is known from two populations north-east of Perth.

Thelymitra manginii looks similar to Thelymitra stellata, T. jacksonii and T. dedmaniarum, with which it was recently confused, however, T. manginii is taller, and has predominantly golden yellow flowers (Brown et al. 1998; Phillimore et al. 1999).
This species inhabits open wandoo woodland on red-brown sandy loam, associated with dolerite and granite outcropping. Associated vegetation consists of Eucalyptus wandoo, E. accedens and Corymbia calophylla, over low scrub of Acacia pulchella, A. saligna, Calothamnus quadrifidus, Melaleuca radula and Hakea lissocarpha (Brown et al. 1998; Phillimore et al. 1999).
Flowering occurs from late Oct. to Nov. As with other WA terrestrial orchids, seed germination and seedling growth of T. manginii are reliant upon an interaction with symbiotic soil fungi. This association continues into adulthood. A suspected pollinator is a beetle, the common Chrysomelid (Diaphanops westermanni). However, this beetle is not believed to be a specific pollinator as it will visit most flowering plants (Brown et al. 1998; Phillimore et al. 1999).
The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
