Very similar in structural characters to 0. fruticulosum, Burch., but is readily 
distinguished by its different appearance. It is evidently a larger plant, with 
larger leaves and flowers, the racemes being much stouter and when in fruit 
§-2 in. in diam., those of O. fruticulosum being less than or scarcely 4 in. in 
diam., the narrow wing on each side of the nutlets seems wanting in the latter 
species, in which the nutlets are also smaller. 
3. O. americanum (Linn. Amoen. Acad. ed. 1, iv. 276); a much- 
branched herb; stems obtusely or obscurely 4-angled, pubescent 
with short recurved hairs, usually bearded with long hairs at the 
nodes; leaves spreading, thinly pubescent to glabrous ; petiole 2-4 
lin. long; blade 4-2} in. long, }-§ in. broad, flat, lanceolate or 
ovate-lanceolate, about equally acute at each end, entire or obscurely 
toothed; racemes numerous, 4-8 in. long, of many equidistant. 
6-flowered whorls; bracts 14-2 lin. long, ovate, acute, persistent or 
deciduous ; pedicels 1} lin. long, pubescent ; calyx deflexed, 1]-2 
(in fruit 24) lin. long, campanulate, 5-toothed to about the middle, 
pilose outside and inside and ciliate with long white hairs ; upper 
tooth orbicular, slightly apiculate, with a tuft of long white hairs at 
its base ; lateral teeth broad at the base, mucronate, much shorter 
than the subulate lower teeth ; corolla more or less pubescent out- 
side ; tube 14-1} lin. long; upper lip about 1} lin. long, shortly and 
subequally 4-lobed ; lobes rounded ; lower lip 1} lin. long, oblong- 
obovate, obtuse, concave; stamens much exserted; upper pair 
inserted near the base of the corolla-tube, 34 lin. long, with a rather 
long linear hairy tooth at the knee ; lower pair inserted at the base 
of the lower lip, 24 lin. long; nutlets } lin. long, oblong, slightly 
shouldered at the base, glabrous, black. Linn. Sp. Pl. ed. 2, ii. 833..
