Tainia
genus of plants
Tainia, commonly known as ribbon orchids or 带唇兰属 (dai chun lan shu) is a genus of about thirty species of evergreen, terrestrial orchids in the (family Orchidaceae) distributed from India, China, Japan, Southeast Asia to New Guinea, the Solomon Islands and Queensland.
Description
Orchids in the genus Tainia are evergreen, terrestrial herbaceous plants with upright, crowded, thin fleshy pseudobulbs. Each pseudobulb has a single, smooth or pleated leaf. The flower stalk emerges from the pseudobulb on the top of a leafless shoot and bears resupinate yellowish, brownish, red or purple small to moderately large flowers. The sepals and petals are similar in size and shape to each other and several flowers open simultaneously. The labellum is sometimes lobed but always has prominent ridges on its upper surface.
Taxonomy and naming
The genus Tainia was first formally described in 1825 by Carl Ludwig Blume who published the description in Bijdragen tot de flora van Nederlandsch Indië. The name Tainia is an Ancient Greek word meaning "ribbon", "fillet", "band" or "stripe" but Blume's reason for giving this name is not known.

The following is a list of the species of Tainia currently accepted by Plants of the World Online as of November 2023:

Begin with the source’s own compact description: “Tainia” is genus of plants. The dossier treats that line as a proposition to test through Tainia, genus and plants, not as a finished interpretation.
Why this record matters
The phrase “genus of plants” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 17, 2026. The linked authority identifier is Q2867938. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1825 and 2023.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
