Species of the genus Catasetum occur from Mexico to Argentina, including much of Central America, the West Indies, and South America. The largest number of species is in Brazil.
Biology
They have thick, cigar-shaped pseudobulbs which are clustered. The leaves are pleated in the upper part and deciduous. The pseudobulbs become spiny after the leaves have dropped.
Pollination
The inflorescence is borne on the basis. It consists of very fleshy flowers that are unisexual, which is very unusual for orchids. The colorful male and yellowish-green female flowers are typically situated on different plants, a phenomenon known as dioecy.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Catasetum”, the useful work is to connect “genus of plants” to the records capable of establishing context and consequence.
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 Aug 22, 2025. The linked authority identifier is Q133751. None of the 0 selected statements returned an explicit reference.
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.
