Today "Revison of the African genus Hexalobus (Annonaceae)" was published in Systematic Botany. This stems from the master degree work of Marleen Botermans, so congrats to her!
Here is the link for those who have access. Otherwise you can pop me an email and I ll send it.
You can also find the description of the five species and other info here at afroannons. Check out the Hexalobus link in the generic tree. We definitly need more photos from that genus! So if people have some don t hesitate to send them to me.
