Cheilotheca is a small genus of myco-heterotrophic plants in the family Ericaceae. They obtain their nutrients by parasitising fungi in the Russulaceae family.[1] As of 2025, the genus includes four species.[2]
Etymology
[edit | edit source]The genus was named by Joseph Dalton Hooker in 1876.[3] The name is derived from the Greek word "cheilos", meaning a lip or an edge. The "theca" is a Latin term, meaning covering or sheath. Together they essentially mean "lipped sheath".
Taxonomy
[edit | edit source]Based on morphological analyses, Cheilotheca has been placed in the Ericaceae subfamily Monotropoideae.[4] The exact placement of Cheilotheca within the Monotropoideae is still unknown, but morphologically the genus most closely resembles Monotropa and Monotropastrum.
