Guide for identification of commercial species

Commercial Woods of Brazil is a guide for the identification of commercial species, based on general and macroscopic characters. It is based on the Intkey program, with a database prepared by the Forest Products Laboratory-LPF of the Brazilian Forest Service-SFB (DELTA format - Version 1.0).

Below are the ways to access each field found in the Main Menu:

Species list: in alphabetical order, of all timber species registered in the application's database. Its scientific and popular names are included, allowing access to images and detailed information.

Filter the species: This category leads to a sequence of 11 characteristics, which will bring discrimination accompanied by images: 1. Phytogeographic domain [Amazon, Caatinga, Cerrado, Atlantic Forest, Pampa, Pantanal, Exotic]; 2. Color of the wood [whitish, yellowish, pink, olive, brownish, orange, reddish, grayish, purplish, blackish]; 3. Growth rings [distinct, slightly distinct, indistinct]; 4. Vases [Absent, Visible to the naked eye, Visible with lens (10X), Tracheids]; 5. Vases / grouping [Solitary (+2/3), Solitary / Multiples, Multiple (+2/3), Doesn't have]; 6. Vessels / obstruction (Unobstructed, Obstructed in most, Obstructed in part]; 7.

And tang .; Transverse, 10X magnification; Tangential, 10X magnification; On 2 surfaces, with 10X lens; Invisible.] By choosing a set of these alternatives, the user can identify the material of interest.
