Dedee is spot-on. Black Bean (Castanospermum australe) is a rainforest tree that grows to a decent size in the wetter parts of Quensland and Northern NSW. I don't have any pics myself, (even though there are lots around me, including two seedlings in pots that I keep meaning to plant out along the creek!). It's a much-planted street and specimen tree, with attractive foliage, and is a great attractor of nectar-eating birds like Lorrikeets when flowering. There are pics at this site:

The wood is heavy, dark-brown, coarse-textured and not often highly figured. At ~700Kg/M* it's moderately dense, but fairly easy to work. It suffered from excess popularity in the mid 60s to 70s, as our local answer to teak - you can still find the odd old boardroom round here fitted out with Bean panelling and Bean furniture (in the Danish Modern style, of course). Prior to that, it was mostly used for fence-posts (yes, that is correct!) and flooring, where I grew up. It has pretty-well been cut out as a result of its brief, but too intense moment in the spotlight. Curse those Danes! :wink:
And yes, it's a nice wood, if you want something very dark brown, but has a nasty sting in the tail - most people become highly sensitised to it after quite brief exposure, so if you did manage to source some, plan your piece and get it made in a couple of days and you'll probably be ok!
The only thing I have made from Black Bean in the last 10 years is a little double-radiused plane I use for scooping out chair seats, etc. I'd post a pic, but I'm a newbie here, and haven't figured out how to post pics on this BB, yet.
Cheers,
