Haiti

Many families live directly from the crop. No harvest season is given. The point on the globe is Wikidata’s point for the country, not a field.

The record

Each field carries its evidence: open a chip for the source, the quoted words and the confidence. A field with nothing behind it says so and stays empty.

Region

the Les Cayes commune, in the south

documented

Despite a price of 350–500 $/kg, its worldwide consumption is estimated at 300–400 t/year, of which 60 % comes from the Les Cayes commune of Haiti.

• softened · Haiti is one of the leading producers of vetiver oil, and the crop supports a great many small farmers. With about two hundred compounds on record, vetiver is a chemically complex natural material. Khusimol is among its most abundant alcohols, but the smell itself has been traced to a trace ketone, and the full orchestra creates the unmistakable character. (was: the retired wording is kept in the claims register (row 2279))

GC-11: “over 150 compounds” (GC-11); GC-10: “about 200 compounds already listed” (GC-10): “hundreds” is supported loosely; the old “300+” is not supported. “A chemically complex natural material” is in substance GC-11’s “extremely complex matrix” and GC-10’s “great chemical complexity”. the house’s review (2026-09-30, the copy pass): “hundreds of compounds” → “about two hundred compounds on record” (GC-10; GC-11 says over 150, :19); “Khusimol dominates” → among the most abundant alcohols (GC-10 :16), the smell traced to a trace ketone (GC-11 :22)
