Etymology
The genus is named in honor of Myron William Kimnach (1922–2018), an American botanist and specialist in epiphytic cacti, who was the long-time director of the Huntington Botanical Gardens.
Description
Kimnachia is an epiphytic cactus with hanging, leaf-like stems.
- Stems: Primary stems are cylindrical at the base, but the secondary branches are flattened, thin, and lanceolate (leaf-shaped), often reaching up to 60 cm in length. The margins are slightly wavy or serrated.
- Flowers: Diurnal and very distinct. They are small, tubular to bell-shaped, and usually bright pink to carmine-red. Unlike many other epiphytes, they have a very stiff, almost waxy texture.
- Fruits: Small, globose berries, often translucent or pinkish-white when ripe.
- Seeds: Small, black, and smooth.
Habitat
It grows as an epiphyte in the warm, humid lowland rainforests of the Amazon basin and Central America. It thrives in high humidity and filtered light, often high up in the tree canopy.
Distribution
- Central & South America: Costa Rica, Panama, Colombia, Ecuador, Peru, Venezuela, and Brazil (Amazonas).
Species and Subspecies
Following Lodé (2015), the genus is monotypic:
- Kimnachia amazonica (Type species)
Taxonomy
Originally described as Wittia amazonica and later moved to Pseudorhipsalis, molecular analysis showed that this species represents a distinct evolutionary lineage within the Hylocereinae. Lodé maintains the genus Kimnachia to preserve the monophyly of the subtribe, noting its unique floral structure which differs significantly from true Pseudorhipsalis.
