Kewbooks is having a one-off sale (ends Jan 31). Lots of the books are 50% off. It is great deal for European people. Even though the shipping to the US is a bit steep, it is still a good deal (most of them are cheaper than the used price from Amazon).
For people interested in the biology-side of orchids, this is a great opportunity.
That book looked like a hard-core taxonomy, I hope that it will have good habitat info. By any chance do you have Orchids of Sarawak? If so, do you like it? I was at the border line (because I like Orchids from Borneo), but I didn't order it.
Nope, I don't have that one. Most of mine cover a location or genus that has a decent amount of orchids that I can possibly grow outside here in Southern California. With a few exceptions such as The Orchids of Sumatra and The Orchids of Mount Kinabalu.
