buckeye / Aesculus spp.
Aesculus spp. of the family Hippocastanaceae. Includes at least the following, which should give you some idea of the range of species and common names and the overlap. Not as bad as some woods, but not clearcut either. Living things are like that sometimes. This list is not presented as being exhaustive and in fact there are definitely other Aesculus species that grow outside North America that are not included.
NOTE: "buckeye" and "horse chestnut" are both common names for these woods in the genus Aesculus
3 x 3" flat cut, 3" x 3" quartersawn, 3/4" wide end grain, and a 1/4" x 1/4" end grain closeup. Diffuse porous with uncountable tiny pores, growth rings faint but discernible even with the naked eye partly due to marginal parenchyma, rays extremely faint at 10X and invisible to the naked eye. All authorities agree that the heartwood is light colored and barely distinguishable from the sapwood but this is contradicted by several of my samples and some of the web pics, which all show clearly darker heartwood.
