Jaimehintonia is a recently (1993) described monotypic genus from gypseous soils of Nuevo León, México in the Milla clade of Themidaceae (or Asparagaceae according to APGIV). This clade includes Behria, Bessera, Dandya, Milla, and Petronymphe. It has coarsely tunicate bulbs, purple to pink perianths, and a well-developed hypanthium to which the gynoecium is not fused.
Jaimehintonia gypsophila grows in chalky gypsum soils in Nuevo León and possibly Coahuila, México. The flowers are superficially similar to Androstephium caerulea and are reported to be purple to pink and rarely white. Thad Howard thinks this might be the long-lost Dandya purpusii. In cultivation (Southern California), plants starts growing mid summer (July), well after Bessera have started growing or even flowering. This species grows well in small pots in a mineral mix of mostly pumice and sand and very little organic matter. It does not offset and must be propagated by seed.The foliage is similar to that of Bessera and the flowers appear at the end of August or in early September. The photos below were taken by Dylan Hannon. The appearance of a pink flowered plant in 2016 (3rd photo) alongside the "typical" lavender colored flowers was a surprise.
