Not sure where you're located, but Boards & Beams in the Fairfield/Pine Brook area has a big selection of hardwoods, although I've only bought quartersawn white oak from them. Their website has listings of species, available dimensions, & pricing.
Blue Ridge lumber in Hackettstown has a small selection of hardwoods. I've bought cherry & mahogany there, IIRC.
Also, Kuiken Brothers has a few species. I've gotten maple & mahogany from them at their Roxbury location.
