Subspecies and
varieties
-- Q. tonduzii Seemen 1904 (A. Camus n° 324)
= Q. seemannii var. or subsp. tonduzii (Seem.) A.E. Murray 1983
differs from Q. seemannii in lacking the pubescence at leaf base adaxially, and in having an angle between lateral veins and midrib less open; Costa Rica; this taxon is very close to Q. seemannii (identical ??); Burger (1977) considers Q. seemannii as a complex, regarding its great variability, which includes probably Q. tonduzii and Q.gulielmitreleasei.
