68 COMPOSITE. LiATRis. 



pappus evidently plumose, or mmutely and densely plumose-barbellate. 

 — EuLiATRis. (Euliatris & Suprago, DC.) 



* Imier scales of the {4-5-Jlovered) involucre longer than the corolla, produced into a 

 dilated and Ugulate colored appendage : pappus very plumose. (Calostelma, Don.) 



1. L. eles:ans (Willd.) : stem and involucre villous-pubescent ; leaves 

 glabrous, punctate; the radical ones spatulate or oblanceolate, 3-5-nerved ; 

 the upper cauline ones linear, short, spreadina; or reflexed, often mucronate ; 

 spike or raceme virgate, dense; the pedicels bracteolate, often very short ; 

 scales of the invohicre 10-12, glandular ; the appendages of the inner ones 

 ovate or lanceolate (bright purple or sometimes white), spreading : acheuia

/3. raceme compound (doubtless an accidental or occasional state). 



Dry barren soil, Virginia to Florida ! Louisiana ! and Texas ! Aug.- 

 Sept. — Stem 3-5 feet high, strict. Spike or raceme compact, a foot or more 

 in length. Bristles of the pappus about 18, in a single series. 



* * Scales of the involucre very nuvicrous and inilricated in several series, without pe- 

 taloid appendages : heads (feu-) cylindrical or slightly clavate, many- (20-60-) 



floicered: hbcs of tlie corolla hirsute within ; pappus very plumose. 



2. L. squarrosa (Willd.) : pubescent or hairy, or nearly glabrous, very 

 leafy ; leaves linear, elongated, rigid, scarcely punctate ; the lower ones 3-5- 

 nerved ; the radical very long; heads few (sometimes solitary), sessile or on 

 short pedicels, manv-flowered ; scales rigid, ciHate, not punctate, with more 

 or less elongated and pointed foliaceous spreading extremities; the inner 

 ones mucronate-acuminate ; the outermost often bracteolate and resembling 

 the upper leaves; achenia minutely pubescent. — Wdld. ! I. c. ; Michx..' fl.

p. Jloribunda : heads numerous (20 or more), in a somewhat paniculate 

 or branched raceme ; the pedicels, or rather branches, elongated and leafy. 



y. compacta: glabrous; leaves crowded, very narrow; heads several, 

 closely sessile, approximate; scales of the involucre lanceolate, with long 

 mucronate points, all erect ; the exterior linear and resembling the upper- 

 most leaves. 



6. intermedia (DC.) : tnostly hairy ; heads (1-5) turbinafe-cylindrical, pe- 

 dicellate ; exterior scales of the involucre elongated and foliaceous, erect; the 

 interior acute, scarcely or not at all squarrose. — L. intermedia, Lindl. bot. 

 reg. t. 948. 



Dry barren or sandy soil. Upper Canada! to Florida! and Texas I (y. 

 Arkansas, Dr. Leavenworth!) July-Sept. — Stem 1-3 feet high, often nearly 

 glabrous, sometimes almost hirsute, as well as the leaves and involucre. 

 Heads about an inch long; the points of the upper scales often ])urplish. 

 Flowers bright purple. Bristles of the pappus 18-20, often purplish. — The 

 var. y. is the most remarkable form; but in the ordinary plant the scales are 

 sometimes erect. Through the not uncommon var. 6. thisspecies seems almost 

 to pass into L. cylindracea, which however it is perhaps safer to consider 

 distinct. — Blazing Star. Bid 'on Snake-roof. Rattle-snake' s-master. (One 

 of the popular antidotes for the bite of the Rattle-snake.)
