quartersawn plank

planks listed as koto / Pterygota macrocarpa

veneer listed as koto / Pterygota bequaertii

steamed veneer listed as anatolia / Pterygota bequaertii

veneer listed as pterygota / Pterygota macrocarpa ("pterygota" is one of the common names for the species, even though it is a genus and so applies to a LOT of woods

listed as quartersawn veneer although the 2nd one does not look quartersawn to me

listed as steamed veneer

listed as unsteamed veneer
