1.1. 2.ColeostachysA. Juss., Ann. Sci. Nat., Bot., sér. 2, 13: 329. 1840. Type species. Coleostachys genipifolia A. Juss. Notes. Coleostachys is represented by a single species (not threatened; Suppl. material 1) of monopodial shrub endemic to non-flooded forests of the Amazon rainforest, South America (Almeida et al. 2020; POWO 2024). A comprehensive taxonomic revision was presented by Almeida and Hall (2016), but the information on type specimens presented by these authors was incomplete. Jussieu (1840) did not specify which specimen is the holotype nor in which herbarium it was deposited, therefore needing the lectotypification presented below.
