Abstract
Abstract This study defines and characterizes the species of Linaceae occurring in Reserva Ducke. We analyzed material collected mainly during the Project Flora of Reserva Ducke. Two genera, each with one species, are recorded: Hebepetalum humiriifolium and Roucheria columbiana. We present species descriptions, taxonomic comments, illustrations, habitat information, geographic distribution and an identification key to species of Linaceae.
Highlights
Linaceae comprises 13 genera and 260 species (McDill & Simpson 2011)
We present an identification key, a taxonomic description with comments, illustrations, habitat information and geographic distribution for the species of Linaceae known to occur in Reserva Ducke
In the Reserva Ducke protection area, we recorded two species of the six species of Linaceae reported for the Amazonas state (BFG 2018; Secco 2015)
Summary
Linaceae comprises 13 genera and 260 species (McDill & Simpson 2011). The family is widely distributed in the Tropics and along the Neotropical region it is represented by four genera and 19 species (Secco 2012). Roucheria Planch are both reported as Hugoniaceae in the Reserva Ducke guide, with each genus containing a single species (Sothers et al 1999). We present an identification key, a taxonomic description with comments, illustrations, habitat information and geographic distribution for the species of Linaceae known to occur in Reserva Ducke.
