230 DESCRIPTION OF SPECIES. 



Comparing this species lo Cinchona yEsculapii, Ung.,"Syllog.," iii, p. 10, 

 pi. ii, figs. 6, 7, the leaves are seen to be of the same form though smaller, 

 and the nervation of the same type; the fruits are broader and shorter in 

 the American species, and not distinctly splitting. They are racemose- 

 paniculate, like those of Cinchona Vellozii, D. C, figured by Unger, I. c, fig. 4.

Plate XLVIa, Figs. 6, 7. 



Heer, "PL Alask.," p. 36, pi. iii, fig. 13. 



Leaves large, cordate-emarginate at base, obscurely serrate-crenate, penninerve ; 

 secondary nerves divided in the upper part, craspedodrome ; nervilles simple, close, 

 rarely forking ; surface puuctulate. 



The leaves are oval, apparently rounded to a short point, about 9 

 centimeters long, 7 broad, deeply cordate at base. The lateral nerves are 

 thin, flexuous, with subdichotomous divisions, the tertiary nerves being at 

 an open angle of divergence and flexuous. These fragments do not differ 

 in their characters from those of Heer's species; even the size is about the 

 same. The secondary nerves are somewhat more oblique but only on one 

 side by deformation of the leaf. The epidermis is distinctly punctulate 

 as by glands at the base of hairs.

Viburnum asperum, Newby. 



" Later Ext. Fl. of N. A.," p. 54, pi. xvi, fig. 8. 



Leaves ovate, acuminate, rounded at base, equally acutely serrate; secondary 

 nerves strong, close, parallel, divided outside, craspedodrome. 



The leaves are small, averaging 5 centimeters long, 3 broad below the 

 middle, from which they taper upward to the acumen; the border teeth 

 are acute and deep, and the strong lateral nerves are joined by simple 

 parallel nervilles at right angles.
