Acacia World

Vachellia tortilis near Gondar, Ethiopia, 13.10.11

Dear Reader:

You have found my home page for the friends of Acacias and all people interested in these
and related trees and shrubs and their worldwide distribution. It is organised by continent and
country and will be detailed further as necessary. Ultimately there should be at least one page
with the respective pictures from each of the nearly 1.400 known species.

In August 2011 the long discussion on the split of the genus Acacia into five new genera has been ended. (see:http://www.scienceinpublic.com.au/media-releases/the-acacia-debate). Now my website will to be adapted by renaming the species according to the new taxonmy. New combinations in
the genera Senegalia and Vachellia as well Mariosousa have already been published by Seigler, Ebinger and Miller. The American species in this website have already been changed accordingly. The book from Maria de Lourdes Rico-Arce treats the American species as a single genus with the exception of Acaciella, which she had revised in 2006.  

Kodela and Wilson described the new combinations in the genus Vachellia from Australia.

My main interest covers Southern Africa and the United States of America. Anyhow, I will only be
able to contribute pictures for some of the many species. Readers and interested persons in
Acacia may send me their pictures of Acacia (plant in natural habitat; bark, flower, pods, leaves,
thorns etc.) by e-mail or CD and I will include them in my website as possible.

In April 2006 I started a NEWS section, where I add some news each month - or as they become availavble.

This website is not commercial. All pictures, however, fall under the author`s copyright -
if not mentioned otherwise - and may not be used further without special permission.
Links to other sites have been made without commercial aspects in mind.

Shortly after I first launched this website the wonderful website World Wide Wattle was published.
There you can find tons of good info on Acacia, especially the Australian species.

Based on their studies of the  genomics of Acacia s.l. Joe Miller has set up an acacia website:

 I also like the article of W.P.Armstrong on

Under Genus Aculeiferum I summarized 89 Senegalia plus 15 Acaciella plus 11 Mariosousa species.
.It remains to be seen, if these Genera-names will now be adopted
