Genus Pterocarya

One of the aims of our project is to produce a richly illustrated booklet on the genus Pterocarya. We have started the photographic documentation of this group only recently. Nevertheless, three species are already very well represented in our iconographic collection: P. fraxinifolia, P. rhoifolia and P. stenoptera (flowers, fruits, leaves, habitats, etc.). This summer we have collected also some photos form natural habitats of P. hupehensis and P. macroptera from China and P. tonkinensis from Vietnam. The entire collection counts now ca. 1,500 pictures and is growing constantly.
