Dr. James thinks the fruit of this plant never becomes pul- 

 py and succulent, and we believe, such is now the opinion of 

 Mr. Nuttall, since he has had an opportunity of examining it 

 in its native situation. 



We have followed Kunth and Sprengel in referring the Ma- 

 dura to Broussonetia, and in considering it identical with the 

 Morns tinctoria of Sloane and others. The Arkansa appears 

 to be the most northern limit of this tree. To the south, it 

 extends into Mexico, and thence to New Grenada and Brazil, 

 and is also a native of the West Indies.

 ceis, subintegerrimis, obtusiusculis, basi inequalibus, supra 

 papilloso-scaberrimis, subtus venis elevatis reticularis, pubes- 

 centibus ; pedunculis 1-floris. 



Hab. Base of the Rocky Mountains. 



Obs. A tall shrub. Branches compressed ; younger ones 

 villous. Leaves about an inch and half long, obtuse, or a 

 little acute, not acuminate, of a firm and almost coriaceous 

 texture; margin with sometimes three or four serratures ; 

 upper surface shining, but very scabrous ; beneath reticulated 

 with prominent veins, pubescent and slightly scabrous ; peti- 

 oles about three lines long. Fruit globose, solitary, on re- 

 curved pedicels one fourth of an inch in length. 



This species is very distinct from C. occidentalis fi. integri- 

 folia of Nuttall.
