Leaf venation ofOcoteaspecies (Lauraceae) from the Reserva Natural Vale, Linhares, Espírito Santo, Brazil

Abstract

With the aim of recognizing and identifying both fertile and sterile specimens of Ocotea from the Reserva Natural Vale, Linhares, we analyzed the leaf venation pattern of 31 species, 13 of them being described and illustrated for the first time. A dichotomous identification key was built from a matrix of 12 venation characters and 36 states, which allowed to distinguish the taxa.

Leaf venation of Lauraceae species (excluding Ocotea) from Bahia, Brazil

“…As pointed out by Moraes et al (2021a), the most comprehensive study on leaf venation of Lauraceae has been undertaken by Klucking (1987), who analyzed leaves of “564 species from 31 genera”. Alongside Klucking’s work, a few authors have provided data on the leaf venation of the taxa treated here.…”

“…An account on the leaf venation terminology used here has been provided in detail by Moraes et al (2021a,b), based on the works by Hickey (1973, 1979), Dilcher (1974), Klucking (1987), Hyland (1989), Pole (1991), Christophel and Rowett (1996), LAWG (1999), Nishida and Christophel (1999), and Ellis et al (2009).…”

“…In these works, detailed information on the literature available to this topic has been provided. As pointed out in Moraes et al (2021a), leaf features of the Lauraceae have been shown to be helpful for identification of taxa, which is particularly relevant for sterile material. However, this type of information is relatively scarce for the Brazilian species of the family and, therefore, for the species treated here.…”

“…In two foregoing papers, the leaf venation of 31 species of Ocotea (Moraes et al, 2021a) and of 20 species of another 11 genera of Lauraceae (Moraes et al, 2021b), was studied in collections from the Reserva Natural Vale (RNV), Linhares, Espírito Santo state (Southeast region of Brazil). In these works, detailed information on the literature available to this topic has been provided.…”

Leaf venation of Ocotea species (Lauraceae) from Bahia, Brazil

“…In a foregoing paper (Moraes et al, 2021), the leaf venation of 31 species of Ocotea was studied from collections of the Reserva Natural Vale (RNV), Linhares. In that work, detailed information on the literature available to this topic and an account on the current knowledge of the genus Ocotea have been provided.…”
