I have a several month old N. singalana coming shortly that I am pretty excited about. From what I have read they don't sell for very much so even though they would be considered one of the "toothy" neps they certainly aren't up there with the big three or four that need no introduction. I also have seeds arriving shortly so it will be nice to see what one looks like that was grown from seed last Spring. I downloaded every picture I could find of it and am impressed.
