feather-veined, thick and rigid: the upper closely sessile by a broad base, slightly 
serrate, the uppermost entire: heads large, over 30-flowered: the rays 7 to 10.—Dry 
soil throughout Texas. Varies with smaller heads, looser inflorescence, and greener 
more scabrous leaves. 
20. S. corymbosa Ell. Stem and leaves (except their margins) quite smooth and 
glabrous, green: heads 6 to 10 mm. long, in looser inflorescence: otherwise asin the 
last.—A rather local species of the Gulf States, and said to occur in Texas. 
++ s+ Leaves more or less 3-nerved, linear or linear-lanceolate, rigid and punctate. 
21. S. nitida Torr. & Gray. Stem 6 to 9 dm. high, very smooth except the mi- 
nutely hirsute summit and inflorescence: heads numerous in the corymbiform cyme, 
about 14-flowered: rays 2 or 3, large: involucral bracts narrowly oblong: achenes 
10-nerved.—Dry pine woods and barrens of western Louisiana and Texas. 
22. S. pumila Torr. & Gray. Dwarf, many-stemmed from a woody branching 
and cespitose caudex, glabrous throughout; cyme glomerate-fastigiate: heads 
narrowly oblong, 5 to 8-flowered: rays 1 to 3, short: involucral bracts rigid, some- 
what keeled, and with small green tips: achenes 5-nerved.—Rocky dry places, 
northwestern Texas. 
§ 2. EUTHAMIA. Corymbosely much branched: heads small, sessile, in little clusters 
crowded in flat-topped corymbs; the losely appressed involucral bracts somewhat 
glutinous : rays 6 to 12, short, more numerous than the disk-flowers: leaves nar- 
row, entire, sessile. 
23. S. tenuifolia Pursh. Slender, smooth but resinous-atomiferous and glutinous: 
leaves very narrowly linear, mostly 1-nerved, dotted: heads obovoid-club-shaped, in 
numerous clusters of 2 or 3, disposed in a loose corymb: rays 6 to 12: disk-flowers 5 
or 6.—Extending into Texas from the Atlantic States. 
24. S. leptocephala Torr. & Gray. With more simple branches, wholly smooth 
and glabrous except the margins of the leaves, which have a prominent midrib, very 
obscure lateral veins, and no apparent veins: involucral bracts and heads narrower: 
rays 8 to 10: disk-flowers 3 or 4.—Low grounds, western Louisiana and Texas. 
23. BELLIS Tourn. (Dartsy.) 
Low herbs, our native species leafy-stemmed, with many-flowered 
radiate heads, numerous pistillate rays, herbaceous equal involucral 
bracts in about 2 rows, conical naked receptacle, and obovate flattened 
wingless achenes without any pappus. 
1. B. integrifolia Michx, (WESTERN DaIsy.) Diffusely branched, 1 to 3 dm. 
high, smoothish: leaves lanceolate or oblong, the lower spatulate-obovate: heads on 
slender peduncles: rays pale violet-purple.—Low grounds, extending into Texas (at 
least as far west as Gillespie County) from the southern Mississippi States. 
24. APHANOSTEPHUS DC. 
Leafy-stemmed branching pubescent herbs, with solitary terminal 
daisy-like heads, white to violet-purple rays, broadly lanceolate involu- 
cral bracts in few series (the outer shorter), and prismatic achenes, the 
broad truncate apex bearing a short coroniform pappus; otherwise as 
Bellis. 
* Pappus a very short crown with aciliate-fringed edge: base of corolla-tube seldom thick- 
ened. 
1. A. ramosissimus DC. Erect or at length diffuse, slender, hispidulous-pubes- 
cent: upper leaves linear or lanceolate, entire or few-toothed; lower laciniate-pinna-
