Description of the Species, Euthales macrophylla. Root 
perennial. Stem herbaceous, erect, thick, perfectly smooth, as is 
the whole plant, branching out into a dichotomous loose spreading 
panicle, attaining the total height of two or three feet. Leaves on 
the lower part of the stem very large, attaining sometimes the length 
of six inches, those in the upper part gradually smaller, few and 
remote, and degenerating at last into mere bracts, all the leaves are 
opposite, oblong, somewhat pointed and bordered by a few coarse 
sharp teeth, narrowed at the base into a short footstalk, smooth and 
rather thick in consistence, irregularly three-nerved or almost penni- 
nerved. On some of the sterile branches the leaves become alternate, 
and are borne on longer stalks. Peduncle solitary, arising from the 
dichotomies of the panicle, one-flowered, slender, bearing no bracteolae. 
Calyx green, with the upper segment leaf-like oblong, about four 
lines long, the others not half that length. Corolla yellow, about 
three quarters of an inch diameter, each division with a thickened 
lanceolate centre, somewhat greenish on the outside and bordered by 
51.
