LiATRis. COMPOSITE. 71 



Dry pine barrens, N. Carolina to Georgia! and Florida! Aujj.-Oot. — 

 Stem 2-4 feet high. Radical leaves resembling tliose ol Piinis palusiris. as 

 remarked by Nuttall (a few of the exterior sometimes 2 lines broad), rigid, 

 forming a close tuft in the manner of Xerophyllum. Raceme elongated ; 

 the i)edicels 8-12 lines long. Flowers pur])le. Achenia turbinate. Pappus 

 scarcely plumose to the naked eye ; the bristles 20-25. — Like most species 

 of tliis .section, the ])edicels are sometimes elongated and branched, forming a 

 paniculate inflorescence. Heads usually quite small. 



t + Pappus densely barbcllate : heads 3-40-flowered. 



8. Z«. sccM«f/a (Ell.) : minutely pubescent or glabrous; stem slender, de- 

 curved; leaves linear, short, rather obtuse, the upper ones bract-like ; raceme 

 virgale; the heads all turned to one side, on short mostly recurved andbracf- 

 eolale pedicels, 4-5-flowered ; involucre cylindrical; scales 12-14, with 

 slightly scarious margins, often resinous-punctate ; the exterior oval and very 

 short; the interior as long as the pappus, oblong-lanceolate, mucronaie-acu- 

 minate ; achenia villous : pappus minutely and densely plumose-barbellate.

Dry sandy soil, S. Carolina ! to Florida ! Aug.-Sept. — Stem 1-3 feet 

 high. Raceme G-12 inches long, curved, rarely slightly compound, beauti- 

 fully unilateral. Heads 6-8 lines long; the scales appressed, mostly 1- 

 nerved. Bracts and bracteoles subulate, very short. Flowers light purple. 



9. L. gracilis (Pursh) : somewhat cinereous-pubescent or nearly gla- 

 brous; stem slender, simple, hearing numerous heads in a long virgate ra- 

 ceme, sometimes compound or paniculate ; leaves linear or lanceolate-linear, 

 short, 1-nerved, often sparsely pilose-ciliate towards the base ; the lower ones 

 lanceolate, obtuse ; heads (small) on divaricate pedicels, few-flowered ; 

 scales of the somewhat cylindraceous involucre few, oblong or elliptical, ob- 

 tuse, resinous-punctate, appressed, shorter than the barbellate jiappus; ache- 

 nia turlinate, villous. 



a. nearly glabrous ; raceme elongated, simple, or slightly compound at the 

 base ; heads (5-7-flowered) on elongated divaricate, or even reflexed, simple 

 pedicels. — L. gracilis, Pursh, Jl. 2. p. 508. 



/i. heads 3-5-flowered, in a slender virgate raceine, on filiform more or 

 less elongated divaricate (or somewhat reflexed) pedicels; of which the 

 lower are furnished with scattered bracteoles similar to the exterior scales of 

 the involucre, and rarely bearing one or two suhsessile lateral heads ; scales 

 of the cylindraceous involucre pubescent and ciliate; the outermost very 

 short, often slightly acute. — L. pauciflosculosa, Nutt. ! in jour. acad. 

 Philad. 7. p. 71. 



y. raceme virgate, simple, or frequently branched or paniculate below; 

 heads (3-5-flowered) on short divaricate pedicels, or sometimes alniost ses- 

 sile ; otherwise as in /3. 



(5. inflorescence entirely paniculate; the branches simple, ascending; a 

 few of the up])ermost only bearing single heads, short ; the lower successive- 

 ly elongated, slender, bearing few or several racemose (3-5-flowered) heads, 

 on short pedicels, or sometimes almost sessile; otherwise as in j3. and y. 



Pine barrens, Georgia ! Alabama! and Florida ! y. Alnhnma, Mr. Buck- 

 ley ! Aug.-Oct. — Stem 1-3 feet high, usually clolhed with a minute some- 

 what cinereous pubescence. Leaves rather tliick, spreading, minutely 

 punctate, often obtuse, tapering to the base; the upper 1-2, tlie lower .3-5 

 inches in length, sometimes hairy. Raceme, when simjjle, 4-15 inches 

 long; with the pedicels IJ to 2 inches long in Pursh's plant {herb. Banks), 

 nearly an inch long (about the length of the bracieai leaves) in our var. (i., 

 shorter, but very variable in the other forms. Heads smaller than in any 

 other species of this section, except L. tenuifolia ; the scales of the involucre 

 7-9, mostly pubescent and ciliate. Flowers bright purple. — The plants
