this species, but intermediate in leaves and general appearance 
between A. Huntii and A. majus.

Perennial: stout and coarse, a couple of feet*high: stem some- 
what purplish, glabrous or with a few short hairs at the nodes: 
cauline leaves short-petioled, deltoid, a span long and wide, bipin- 
nate and with the lowest segments often pinnatisect; segments 
crisped, infolded, or overlapping, acute, setulously biserrate, very 
veiny and somewhat pubescent beneath; petiole-sheaths and rachis 
coarsely and retrorsely white-hairy: umbels subcorymbose, their 
stout peduncles subtended by reduced leaves or the uppermost 
naked, compound, without primary involucre; umbellets dense, 
stout peduncled, the involucre of broadly white-margined ciliate 
and somewhat pubescent bractlets: flowers white: fruit glabrous, 
obconical-oblong, 12 mm. long; styles and broadly conical stylo- 
podium of about equal length.— More closely related to C. hirsutum 
than to C. aromaticum.
