Hello Ralf,
I ordered the book about the aroid.org:
http://www.aroid.org/literature/IndoAmorph/ and wrote to Albert Huntington:
http://www.aroid.org/aroiders/showmember... rget=huntington
I don't know if it's still available. But it is a very beautiful book; good text, beautiful pictures and illustrations.
At the time, it cost 39.95 U.S. dollars + 22.50 U.S. dollars postage.
To the other books on the aroid.org
http://www.aroid.org/literature/ I only know zT what...
I ordered Deni Bown's book directly from her (if I remember correctly I had contact via the aroid-L); but it seems to be out of print.
I do not know Marc Gibbernau's book, but I make a very interesting impression; here you can browse something:
http://sciencepress.mnhn.fr/en/collectio... uyane-francaise and also buy it....
Whether the book is in French, I can not tell.....
Araceae of the Peninsular Malaysia can be downloaded here:
https://www.researchgate.net/publication... nsular_Malaysia
The Genera of Araceae is also available here as pdf:
https://www.researchgate.net/publication... nera_of_Araceae
The History of Araceae is available here, but this is pure text.....:
www.aroid.org/literature/croat/croat_araceae_history04.pdf
From Wilbert Hetterscheid there are some articles as pdf to download
https://www.researchgate.net/profile/Wilbert_Hetterscheidthere are some very interesting articles; Eg:
https://www.researchgate.net/publication... is_Engl_Araceae
https://www.researchgate.net/publication... phallus_titanum
Otherwise, I can't give you any more literature from the stand-up....
Maybe someone else has a few tips.
Happy downloading/reading,
Bernhard.
