SYNGENESIA iEQUALlS. 
271 
Root perennial. Stem erect, 4 — 6 feet high, furrowed, unarmed, some- 
what glabrous but sprinkled with a few lanugifiouS^flBhrsf 'branching more 
than in any other species with which I am acquainted. Leaves sessile, 1 
—2 feet long, deeply pinnatifid, a little hairy along the veins and midrib, 
armed with very acute spines along the margins and angles. Flowers 
somewhat paniculate. Peduncles on small branches, nearly naked, slen« 
der and a little hairy. Involucrum campanulate, ventricose; scales lan- 
ceolate, closely appressed, a little hairy, viscid and armed with a short 
somewhat recurved spine. Corolla much longer than the involucrum, of 
a pale purple colour. Seeds oblong, glabrous, crowned with a beautifully 
feathered caducous pappus. Receptacle flat, bristly. 
This species of Cnicus, by far the most common in the low country of 
Carolina and Georgia, appears to have been overlooked by both Walter and 
Michaux, at least the C. Glaber of Mr. Nuttall is the only species whose 
description accords with the character of our plant. I once considered it as 
the C. Repandum, of Michaux, but the plant I have described under that 
name agrees more accurately with his observations. 
Grows in cultivated lands, very common about buildings. 
Flowers May-— August.'

Stem erect, 3 — 6 feet high, in my specimens very hairy, and covered 
with cobweb-like tomentum. Leaves long, deeply pinnatifid, the segments 
very generally 2-lobed, the lobes ovate and spiny, woolly underneath, the 
margin very irregularly armed with spines. Flowers solitary, terminating 
the branches, which are generally leafy, up to the base of the involucrum:; 
scales of the involucrum ovate, acute, crowned with a long spine. Co- 
rolla bright purple. Seeds smooth, crowned, with a feathered pappus. 
Grows in the upper districts of Carolina. 
Flowers June — July.
