4. Hieracium venosum, Linn. Rattlesnake-weed. 



Stem scape-like, naked or with a single leaf, smooth, slender, loosely corymbose-paniculate 

 above, with long slender smoothish peduncles ; radical leaves obovate or spatulate-oblong, 

 entire or obscurely denticulate, hairy on the margins and midrib, the veins usually purple ; 

 involucre smooth, or minutely glandular-hispid toward the base ; achenia linear, scarcely 

 narrowed at the summit. — Linn. sp. 2. p. 800 ; Pursh, fl. 2. p. 502 ; Ell. sk. 2. p. 262 ; 

 Bigel. fl. Bost. p. 288 ; Hook. fl. Bor.-Am. 1. p. 297 ; Beck, hot. p. 166 ; Darlingt. fl. 

 Cest. p. 446 ; DC. prodr. 7. p. 217 ; Torr. ^ Gr.fl. N. Am. 2. p. 478. Stenotheca venosa, 

 Monn. I. c. p. 72. 



var. subcaulescens : stem more or less leafy near the base ; the cauline leaves sessile or 

 clasping. Torr. ^ Gr. I. c. H. Gronovii, Linn. herb. <^ sp. 2. p. 802 (excl. syn. Gron.) ; 

 Michx. fl. 2. p. 87 (var. a.) ; DC. I. c. 



Stem or scape 1-2 feet high. Leaves spreading on the ground, then tapering to a short 

 petiole, smoothish except on the margins and midrib, usually variegated with deep purplish 

 veins, and sometimes wholly purple underneath, but often uniformly pale green. Panicle 

 widely spreading, and consisting of few heads on forked almost filiform peduncles, which are 

 very sparingly glandular. Involucre about 20-flowered ; the flowers bright yellow. 



Dry soils, and in open sandy woods ; common. June - July. This is one of the numerous 

 plants supposed to be antidotes to the bite of the Rattlesnake, but its virtues are probably 

 overrated, if not altogether imaginary.

Stem slender, leafy, loosely paniculate, villous towards the base, smooth above ; leaves 

 lanceolate, acute at each end, denticulate with spreading teeth, thin and smooth ; panicle 

 compound , the peduncles slender, divaricate and smooth ; scales of the involucre few, smooth ; 

 achenia not contracted at the summit. — Linn. sp. 2. p. 802 ; Michx. fl. 2. p. 86 ; Pursh,
