About Cardiochilos
Cardiochilos is a genus of flowering plants belonging to the orchid family, Orchidaceae. This genus is monotypic, meaning it contains only a single species: Cardiochilos williamsonii.
Description and Ecology
Cardiochilos williamsonii is characterized as a monopodial, epiphytic herb. The plant typically features stems up to 10 cm in height and fleshy roots that can extend up to 20 cm in length. Its flowers are solitary and non-resuspinate, meaning they do not invert themselves after opening. These flowers are borne on peduncles that are described as hairy. The most distinctive characteristic of the flowers, and indeed the genus, is the labellum, which is heart-shaped. This feature is directly reflected in the genus name, Cardiochilos, derived from the Greek words 'kardia' (heart) and 'cheilos' (lip).
Ecologically, Cardiochilos williamsonii has been observed in mist forests. It thrives at significant elevations, specifically noted at 2590 meters above sea level. The specific geographic origins beyond its habitat type are not detailed in the provided information, but its presence in mist forests suggests a requirement for high humidity and specific temperature ranges typical of such environments.
