short, equal or unequal. Corolla regular ; tube rather long, sometimes 

 rather thicker at base; lobes of limb oftener 6, 3-nerved, valvate. 

 Stamens as many, alternating with lobes of corolla ; filaments inserted 

 at top of tube, 1-adelphous at base, free above ; anthers introrse, 

 2-rimose, marginally coherent in a tube traversed by the style. Glan- 

 dules same in number alternating with stamens and sessile within tube. 

 Germen inferior, 1 -celled; style slender, at slender exserted stigmatose 

 apex not or scarcely dilated or truncate entire. Ovule 1, inserted 

 near apex of cell, descending ; micropyle introrsely superior. Fruit 

 dry, indehiscent, free, crowned with unchanged or scarcely changed 

 calyx ; pericarp longitudinally 4-6-angular, rather hard or suberose ; 

 angles continuous with persistent, raither obtuse, acute or spinescent 

 lobes of calyx. Seed descending ; albumen fleshy ; embryo axile 

 shorter than albumen; radicle superior. — Glabrous annual or oftener 

 perennial herbs ; stem ramose, sometimes foliate or oftener scapelike ; 

 lower leaves rosulate ; all alternate, often rather fleshy, entire, dentate 

 or pinnatifid; flowers in spurious capitules at top of simple or branched 

 scape ; exterior bracts pointless not accrescent, approximate or connate 

 below in an involucre; interior paleaceous; bracts in axils each 

 glomeiTiliferous ; all flowers of the glomerule fertile, or more rarely 

 the exterior male sterile. {South-west, extratrop. And, and suhtrop. 

 east. America.) — See p. 524. 



6. Calycera Cay.' — Flowers (of Boopis) polygamous, 2-form in 

 each glomerule; a few central hermaphrodite fertile; the outer 

 (younger) often male sterile. Other characters of Boopis. — Annual 

 or perennial herbs, glabrous or woolly, erect or procumbent ; leaves 

 alternate, either remote on stem, or rosulate at base, coarsely dentate 

 or pinnatifid; inflorescence capituliform-cymose,on simple or branched 

 peduncle; bracts of involucres free or connate at base; fruit dry, 

 2-form ; germens of larger flowers hardened above and crowned with 

 2-5 hardened spinescent elongate accrescent lobes of calyx ; calyx
