A. Camus : n° 405;|
-- Section Lobatae; sub-section Eugeniaefoliae;
-- Close to Q. pinnativenulosa, which differs from Q. salicifolia in having leaves longly acuminate at apex, with a bristle-tip often in a spiral.
-- Hybridizes with Q.benthamii, Q.cortesii and Q.sapotifolia;
-- Q.mulleri could be a variant with leaves having 25-30 vein pairs at an angle of 60° with the midrib; Mexico (Oaxaca);
-- For some Authors (Susana Valencia-Avalos), Q.eugeniifolia is a true species, but differing from Q. salicifolia only by the pubescence of the lower side of the leaf (in eugeniifolia leaves are glabrous abaxially or have some stellate trichomes near the base); Mexico (Hidalgo, Puebla, Veracruz) à 1400-1900 m ; Costa-Rica and Panama; for some other Authors, it is a variety of Q. affinis.
-- For Govaerts & Frodin (1998) and for the Biological Institute of the National University of Mexico (2003), the following species are true ones : Q.mulleri, Q. seemannii [= salicifolia var. seemannii (Liebm.) Wenz. 1884, = boquetensis Standl. 1940, = citrifolia Liebm. 1854].
-- Q.panamandinea is, for Govaerts & Frodin, a true species; the same Authors seem not to know Q. chiriquensis...(they don't quote this name in their World Checklist of Fagales).
--For Govaerts & Frodin 1998, and for Susana Valencia Avalos 2004, Q.duratifolia is a true species, but not for Linares, J.L., (El Salvador) in 2006.
|-- Q.tonduzii Seemen 1904
= Q.seemannii var. tonduzii (Seem.) E.Murray 1983
differs from Q. seemannii in lacking pubescence at base of blade adaxially; Burger, in 1977, regards Q.seemannii as a complex, because of its great variability, integrating probably Q. gulielmi-treleasei and Q. tonduzii.
