A small genus native to northern South America from Guyana to Brazil. G. laeve (Vell.) Miers, G. sericeum (Sagot) Benth. & Hook.f., and G. vellosii Allemão are recognized locally as having antimalarial properties. These are usually taken as bark decoctions prepared in water (Brazil, Guyana, Surinam) or alcohol (French Guiana).
Indole alkaloids geissospermine (C19H24N2O2+H2O), pereirine (C19H24N2O) and vellosine (C23H28N2O4), and one β-carboline alkaloid are contained.
