pedicels 1 and almost 2 in. long; no kinship to A. Claytoni would 
be guessed from these, but from the same rootstock grew a short 
erect rough condensed plant nearly typical for A. C/laytoni, retain- 
ing its characters because happening to project into the sun. 
Mosholu, N. Y., Se. 30, ’96. 
30% Flagelliform form. Very remarkable in appearance from 
its many long swaying flagelliform branches, each bearing a little 
dense cluster of heads, with — pedicels.

30? Rock-cleft form. Very dark green, but leaves wholly 
different from other dark green Divaricati, and in shape agreeing 
with A. Clayton ; roughish a little on account of scattered hair in 
life, more so when dry; disks reddish brown; rays about 12, 
sometimes 13. Partial to clefts of rock, where it grows in lines 
or scattered clusters ; iis in loose stony soil in their venen

30" Thin-leaf form. Verges toward A. divaricatus, the leaves 
not = pbs when dry ; but quite firm and of a dense texture.

Strong much-branched rigid a with many strongly divari- 
cate verticils each with 3 (or sometimes only 2) leaves and branches. 
Rigid ; stem greenish, angulate ; leaves cordate-ovate, short, small, 
dark green, with broad base. Inflorescence profusely branched, 
greatly divaricated, many of the upper nodes giving off the charac- 
teristic verticillate or opposite leaves and branches. These cases 
are unlike the normal inflorescence of the Devaricati in retaining an 
early suppression of internodes, which in others becomes partially 
obscured by slight separation during development. Examples:

"98, some plants with as many as I2 2-3-leaved verticils ; their rays chiefly virescent. 
— Extreme plants of this form are exceedingly distinct, so 
much so as to seem in habit to indicate distinct generic position. 
Yet I have not felt warranted in assigning even specific rank, for 
the following reasons: Ist, variants grew with it connecting with 
typical A. Claytoni,; as also with A. divaricatus and its flabellate 
form. I would deem this but a slight argument against specific
