 Pl.ite II, Fig. 5. 

 Hayden's "Ann. Rep.," 1874, p. 348, pi. iii, fig. 5. 



Leaf thick, narrowly lanceolate, aciimiuate, entire; medial nerve comparatively 

 thick; lateral veins close, parallel, at an acute angle of divergence, camptodrome. 



The leaf, 5* centimeters long, 11 millimeters broad in the middle, is 

 gradually narrowed downward to the petiole and upward to a somewhat 

 long acumen; the angle of the lateral nerves is 30°; the areolation is 

 composed of round or quadrate polygonal minute areoles. 



This species is closely allied to the preceding; the veins are less 

 oblique and more curved.

ARALIACE^. 



ARALIA, Linn. 

 Aralia formosa, Heer.

 Heer, "Moletein Fl.," p. 18, pi. viii, fig. 3. 



Leaves petioled, triple-nerved, trilobate; lobes dentate, blunt at the apex. 



This species, as represented by American specimens, though positively 

 identified, presents a few unimportant points of difference. In Heer's 

 figures the base of the leaves is wedge-form and the divisions oblique; 

 in those which I have for examination the middle lobe is oval or lance- 



'The name of this species is changed as preoccupied by Heer.
