No sufficient explanation of this form is to be found in shade 
or in richness of soil, the type growing with it in the same condi- 
tions. Such variants may form the whole of a loose plantation ; 
or be outliers from a colony of the type; or be stray individuals 
or stand as individual sports in the midst 
of a colony of the type; hence I do not separate this form as a 
subspecies but regard it as a transient manifestation of that ten- 
dency of the variable type which when much stronger in develop- 
ment produces the form pinguifolius, the ancient Azotia latifolia. 
55" Hetchel form. Some pubescence ; shapes very irregular 
but mainly as the type, of which it is but an extremely harsh 
form ; leaves very rough in life, like sandpaper when dry ; “ rough 
as a hetchel," people call them ; abundant in W. N. Y., etc. 
55? Triangle-hetchzl form. Lower leaves not large, triangu- 
lar-cordate, rather obtuse, very thick and rough; leaves slowly 
diminished up the stem ; stem glabrous, deep purple-red ; inflor- 
escence cylindric-convex, becoming 12 in. high by 6 broad, or in 
smaller plants short-convex, apt to have their pedicels forking in 
5's, instead of trifurcate. Some reniform lower caulines or radicals 
occur. Rays often full violet rather than lilac. Bracts chiefly 
rigid, brownish, acute, with little hair. — Appears intermediate be- 
ween A. macrophyllus and A. multi (formis ; and probably un- 
stable. Highly developed plants appearing very distinct, led me 
to look for evidence subsequent years to determine whether or 
not it should rank as a separate species ; but it seems sporadic.

SE ER form. With narrow tall inflorescence, its lateral 
branches late and much shorter; the distinct roughness of the 
broad-cordate leaves increased upward till the axiles are like sha- 
green. Inflorescence like the last in form, and in frequent 5-fork- 
ing umbelliform ee but leaves and rays like A. macro- 
phyllus. With the type.
