They are sometimes deeply lobbed, possibly assymmetrical in comparison with the central vein. Stems contain a white sap rich in latex. The Paper Mulberry is a species dioecious: the male flowers are catkins, the female flowers are bowls of 1 cm in diameters (glomerules), ruffled of purple hair papiloses which are stigmata (as on the Oasage Orange). The fruits of Blackberries resemble the blackberries of the bramble, but differ from it : the mulberry is a mass of small fleshy fruits, while the mulberry of the bramble results from the single flower the calyx of which is found at the base. Every carpel gives a fleshy element containing a seed..
