Gonystylus spp. of the family Thymelaeaceae, including at least Gonystylus affinis, Gonystylus bancanus, Gonystylus brunnescens, Gonystylus confusus, Gonystylus forbesii, Gonystylus macrophyllus, Gonystylus maingayi, and Gonystylus velutinus, and possibly more.
This is one of those wood names that have numerous species (see directly above) all sold under the same common name and for this one, I would guess that many of the species are quite different, thus the fact that the colors here are all over the place.
my samples: NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K) colors will vary under other lighting conditions
both sides of a sample plank of ramin / Gonystylus bancanus --- HUGE enlargements are present. This sample was loaned to me by Mark Peet whom I thank for this and other contributions to the site.
