This is a very distinct species in the peculiar long aristate teeth of the leaves, 
Which I have not found in any other species of the genus. I have not seen any 
Ype specimen; and according to Bureau's description I believe he mixed his va-

somewhat resembles M. serrata Roxburgh (see p. 302). 
Morus acidosa Griffith! Not. Pl. As. IV. 388 (acidosus) (1854).
