 somewhat pointed with a central bristle ; rays 20-30 in a single series. —

South Carolina ! and Georgia! to Florida! Alabama! and Louisiana ! in 

 wet soil, like all the species. March-April. — Stem 1-2 feet liigh. Lower 

 cauline leaves 4-7 inches long, 1-nerved; the primordial small. Heads an 

 inch and a half in diameter, including the rays. 



2. L. incisa : glabrous ; leaves lanceolate, rather obtuse, sessile, not de- 

 current, sinuate-pinnatitid or incised ; scales of the pappus lacerate or slightly 

 fimbriate at the summit ; rays about 40 (always?) in a double or triple series. 



Georgia, Mr. L. Le Conic! — Plant with the habit of L. puberula, and with 

 the incised or pinnatifid leaves so common in that species; but the achenia 

 perfectly glabrous, strongly striate ; the pappus nearly as in L. Helenium. 

 Involucre glabrous, very short. The rays in the only specimen we possess 

 are in 2 or more series. 



* * Achenia hairy on the angles : pappus Tiervelcss. 



3. L. fimhriata : glabrous or nearly so ; leaves lanceolate or linear-lance- 

 olate, acute, entire or remotely denticulate, often decurrent ; the lower elon- 

 gated ; the radical oblanceolale ; scales of the pappus deeply fimbriate-cleft 

 into capillary segments. — Galardia fimbriata, Mirhx. fl. 2. p. 142 .■' 



East Florida, Dr. Leavenworth ! Texas, Drummond ! Dr. Leavemcorth ! 

 growing in wet soil, and in pine barrens along streams, like all the other 

 species. April-May. — Stem occasionally forked above, 1-2 feet high. 

 Leaves resembling those of L. Helenium. Rays rather numerous, in a 

 single series. Receptacle oblong-conical. The scales of the silvery pappus 

 are fully half the length of the corolla, and beautifully dissected about to the 

 middle into a capillary fringe. — This is very probably not the Galardia fim- 

 briata of Michaux, although it best accords with his character; but, since that 

 name cannot properly be employed for either of the species already described, 

 it may in any case be adopted for the present very distinct species, for which 

 it is very appropriate. 



4. L. puherula (Macbride): stem tomentose-pubescent and somewhat vis- 

 cid ; leaves linear-lanceolate (thickish), often toothed ; the cauline not de- 

 current; the radical sometimes obovate-lanceolate, often incised; scales of 

 the pappus obtuse, lacerate-denticulate at the summit, or nearly entire. — 

 Macbride, in Ell. sJc. 2. p. 445, (excl. syn. {Michx?) ; DC. I. c. Helenium 

 vernale, IValt., fide Ell. 



jS. pinnatijida: radical and lower cauline leaves incisely toothed or pin- 

 natifid. — L. pinnatifida, Schivein. ! herb.; Nutt. ! in trans. Amer. p)hil. soc. 

 {n. ser.) 7. p. 372. 



North Carolina! to Georgia ! and Florida! April-May. — Stem 1-2 feet 

 high, usually fistulous. Head, including the 20-30 rays, often 2 inches in 

 diameter. 



5. L. brevifolia (Nutt.) : stem glabrous below, minutely pubescent at the 

 summit; leaves all entire or obscurely denticulate ; the lower and radical 

 oblong-spatulate, obtuse ; the cauline more or less decurrent; the uppermost 

 lanceolate, often acute; scales of the pappus obtuse, slightly denticulate or 

 lacerate at the summit. — L. puberula, Ell. I. c, partly. 



/?. stem stouter and taller ; leaves larger ; the cauline more strongly de- 

 current. — L. integrifolia, M. A. Curtis ! mss. 



North Carolina! to Alabama! common. /?. Raleigh, N. Carolina, Mr. 

 Curtis ! May-June. — Stem 1-3 feet high, not unfrecjuently slightly branched
