Tropidia (plant)
genus of plants

Tropidia, commonly known as crown orchids, is a genus of about thirty species of evergreen terrestrial orchids in the family Orchidaceae. They have thin, wiry stems with two or more tough, pleated leaves with a flowering spike at the top of the stem, bearing crowded flowers. Species in this genus are distributed across the warmer parts of both the Eastern and Western Hemispheres.
Description
Orchids in the genus Tropidia are evergreen, terrestrial, sometimes mycotrophic herbs which form small clumps. They have thin, wiry stems, sometimes with a few branches. The stems have two or more thin, tough, pleated, lance-shaped to egg-shaped leaves. Crowded white, greenish or brown, sometimes resupinate flowers are arranged on the top of the stem and have the sepals and petals free from each other, or with the lateral sepals joined and surrounding the base of the labellum. The labellum is not lobed but has a pouch or spur at its base.
Taxonomy and naming
The genus Tropidia was first formally described in 1833 by John Lindley and the description was published in Edwards's Botanical Register. The name Tropidia is derived from the Ancient Greek word tropidos or tropideion meaning "keel", referring to the boat-shaped labellum of some species in this genus.
Begin with the source’s own compact description: “Tropidia (plant)” is genus of plants. The dossier treats that line as a proposition to test through Tropidia, plant and genus, 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.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 17, 2026. The linked authority identifier is Q2670134. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1833.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
How to read it
