 jointed hairs like but smaller than those of the stem, uninerved, 

 the margins entire, more or less revolute ; capitula hemispherical, 

 abovit ^ in. in diameter, many-flowered, pedicellate, arranged in 

 a lax corymbose somewhat bracteate terminal panicle 2 to 5 in. 

 in diameter ; bracts like the leaves but smaller ; pedicels ranging 

 up to 2^ in. long, ascending or erect, slender, scabiid ; involucral 

 scales pauciseriate, ultimately reflexed, sublinear or the inner ones 

 subspathulate and lanceolate at the apex, with whitish scarious 

 incise-ciliolate margins, minutely scaberulous on the back, glabrous 

 inside, about ^ in. long, the outer ones shorter ; ray-florets female, 

 uniseriate, ligulate, i in. long ; ray oblong, spreading, white or 

 purple (both colours on the same specimen) ; disk florets herma- 

 phrodite, multiseriate, tubular, i in. long, narrowly funnel-shaped, 

 shortly 5-cleft ; anthers with lanceolate appendages at the apex, 

 obtuse at the base ; style-branches (inclusive of the appendage) 

 very narrowly linear-lanceolate, flattened, papillose on the 

 margins ; achene obovate, scattered with setulfe, rather thickened 

 on the mai-gin and a little constricted about the apex at the ring 

 from which arises the white uniseriate setose suberect pappus of 

 _l_ to y\f in. long ; setfe partially setulose ; receptacle naked, neai^ly

 subrevolute ; capitula sub-hemispherical, ^ to ^ in. in diameter, 

 many-flowered, pedicellate, arranged in a rather lax corymbose 

 bracteate terminal panicle 3 to 8 in. in diameter ; bracts like 

 the leaves but smaller; pedicels rather slender, scaberulous 

 towards the apex; involucral scales paucisei'iate, ultimately 

 spreadmg, sublinear : the inner ones the longest, with narrow 

 whitish scarious margins, acute, i in. long, hispidulous-scaberulous

 female, uniseriate, ligulate, I in. long; ray oblong, spreading, 

 white or very rarely purple-violaceous; disk florets hermaph- 

 rodite, multiseriate, tubular, subcylindrical, i in. long, shortly 

 5-cleft ; anthers with narrow lanceolate appendages at the apex, 

 obtuse at the base; style-branches with narrowly lanceolate 

 appendages ; achene shortly obovate, somewhat compressed,
