formis multumque infra medium in bractearum axillis trifurcata, verticillo unico trifoliato, nunc 
ramulos ac folia prodente, cum brachiis alternante, nonnunquam capitulis ime furce insidentibus; 
abinde solum ad nodos ramiferos foliis singulis parvis. Folia anguste spathulato-ovata, margine 
undulata, in petiolum longum attenuata, superne rubentia, radicalia cum pedicellis 11—2" longa.

The whole plant, except the flower, covered with a white arachnoid tomentum. in about 
13 foot high, virgately branched, with a whorl of three bracts at each node, (besides occasional 
leaves,)leafy at the base, hence scapiform and trifurcate below the middle, with the prongs 
opposite at the bracts, and alternate to a solitary ternate whorl of leaves, which sometimes 
produce accessory branches and leaves from their axils, and sometimes capitula seated in the very 
centre of the trifurcation ; a small solitary leaf at each further branching. Leaves narrowly 
spathulate-obovate, undulate at the margin, attenuate into long petioles, with a reddish tinge; 
radical leaves 14—2 lines long, including the petiole. Involucres sessile, mostly solitary, 
tubuloso-campanulate, acheniform, unilateral along the branches and terminal. Flowers small, 
glabrous, exserted, pinkish or purpurascent. Floral chaff capillary included. 了 Pos6 creek;
