Biology : Terrestrial plants with a growth habit resembling that of Disa; they arise from a ± ovoid tuber which is renewed each year. Sometimes they have sterile shoots that are next year’s fertile shoots. The flowers of most species are unique within Orchidaceae. They are non-resupinate (the hood-like lip is the uppermost floral segment, the other tepals are facing downward). The flowers are never very large but they are often brightly coloured and in dense heads. Sepals and petals are relatively small; they are more or less joined to each other for part of their length and to the lip. The genus got its name from the very distinctive lip having 2 spurs: the mythological two-horned satyrs, half men - half goats. Below the main spurs there may be an additional pair of vestigial spurs. The lip is deeply concave, often almost globular, forming a hood.
Ecology : Genus of some 92 species. Widespread in temperate, tropical and montane Africa, with a few species found in Madagascar (4), Sri Lanka-India-E-wards through to China (4 in Asia). Maps in Kurzweil & Linder 1999: 103, and Pridgeon & al., Gen.orchid. 2: 53, 2001. “Most species appear to be specialized for pollination by one functional pollinator group” (Johnson & al. in Pl. Syst. Evol. 292: 95, 2011).
