Cinnamomum spp. of the family Lauraceae. There are at least 20 species in the genus Cinnamomum that have the word cinnamon as all or part of one or more of their common names (and the genus has over 300 species) and I have no idea which of them are represented on this page. It is a subtropical genus and I have only seen it shown as a burl, although I don't know why that is since reportedly at least a few of the species grow to small sized trees (many are just bushes).
I've never seen this wood, so can't comment on any of the colors in the web pics below but I note that there is not a lot of variation so I suspect that they are reasonably accurate. I also note that the burls look a lot like camphor burls.
my samples: NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K) colors will vary under other lighting conditions
