Not worked very much with Morus. The one in your picture is Morus alba? The one in original question is Morus nigra?

IMO Morus alba or white mulberry or paper mulberry.......not morus nigra but morus rubra or red mulberry.

Ah so there is a white and a black mulberry. Alba means white and nigra means black

I know that but I have yet to become aware of a black mulberry. Ceasing to quote from memory (sketchy at times) I am going to revise my opinion. White mulberry has a smooth shiny leaf surface as the one pictured does. Red mulberry has a "dull dark green and rough surface". Paper mulberry, a 3rd one as I pictured also has a surface with "rough hairs above" as my leaf does. Also found some shrub forms such as Texas Mulberry and Morus Australis (Unryu), but this is obviously not a shrub. I am now placing all my remaining money on white mulberry.

The book i'm refering to show Morus alba as having the leaf you showed Treevet?? Anyhow the book i have access to the now has only two types of Morus in it, so unable to add anymore.Common names get pretty confusing.

The one book I saved the paper mulberry within it's description pages had all 3 listed. I probably have a dozen or more ID books. All 3 mulberries get the funky variable shaped leaves. The paper have very long leaf stems and is described as having pieces of "paper" hanging. It also has a rough surface. I saved it for all those years and ID'd it because it was so unusual having 2 dif. shaped leaves on one tree (Sassafras also comes to mind). The fibrous inner bark is used for making paper in Japan and China another name derivative listed.
