flower large, bright yellow, 9-15” broad; capsule 3’ to 4” long, 
ovoid, or obovoid, rounded above; apetalous flowers borne at 
short intervals along the branches, either singly or in peduncled 
clusters, which are sometimes closer and more numerously flow- 
ered above, but never closely aggregated; outer sepals very short 
and appressed, or rudimentary ; fruiting calyx depressed-globose ; 
capsule globose-triangular, at full maturity spreading 14” to 2” 
broad (late in the season some terminal flowers may be imper. 
fectly -petaliferous, producing capsules which spread 3’), mostly 
three to many seeded; seeds reddish brown, finely and evenly 
papillose, the papille prominent under the microscope and often 
disposed in regular lines. . 
HELIANTHEMUM MajuS (L..). 
Taller, stouter and stricter than A. Canadense, from one to 
two feet high; branches more numerous, simple, much shorter, 
and never at all flexuous, commonly but one to two inches long, 
often less, only exceptionally reaching a length of four inches ; 
entire plant more hoary canescent than in Canadense, with finer 
and closer stellate pubescence, especially on the primary inflores- 
cence, and without the scattering of longer looser hairs usually 
seen in that Species; more closely leafy, the leaves less spreading, 
frequently sub-opposite, or even sub-verticillate, on the stem; 
Onger and relatively narrower, more tapering at base and apex, 
and on slightly longer petioles, the strong tendency to revolute 
Margins seen in Canadense scarcely manifest; furthermore, the 
leaves are thicker and of softer texture, and wilt soon after being 
sathered, which is not the case with the stiffer and harsher leaves 
of the contrasted plant; stem reddish from the first, and early 
Naked for several inches at the base; primary petaliferous flowers 
pale yellow, smaller than in Canadense, several to many (5 to 12), 
racteolate in one to three slender cymose racemes, commonly 
1% inches long, terminating the simple stem, the axillary branches 
eveloping later but rarely overtopping the primary inflorescence; 
Sepals densely downy canescent or softly pubescent, smaller and
