I would recommend The Genus Hoya from Botanova in Sweden. The other books that are out there are overpriced and there are far too many naming mistakes that just cause confusion.

If you don't want to spend money on a book all of the information is available for free from various Hoya web-sites.

Thanks Mike. I am looking for a book to give as a gift. Maybe I should give her the gift of free access to my computer and internet-as long as it is only Hoyas she looks up.
I will have to check out those sites myself!

I am the type to buy books out of curiosity. Even if I have the same information available on the internet I still like to buy books.
My vote is still with the Botanova book and I think it would make a great gift.

That's funny. I am a fan of having all the books on a subject I am "into" also. Even with all the info on the web, I still want the books. I even print out some stuff to read later in bed. Ha. Like I always used to print out all the Stemmas. Ya just can't move some people into the techie age completely, I guess. Ha.
