Bkllis. composite. 189 



Receptacle conical, slightly alveolate. Branches of the style short and hroad. 

 Achenia obovate, compressed, slightly hairy or hispid. Pappus none. — Low 

 herbs (natives of Europe, with a single exception), either acaulescent and 

 perennial, or caulescent and annual. Leaves mostly obovate or spatulate. 

 Heads solitary, terminating the scape or branches. Rays violet-purple, rose- 

 color, or white. — Daisy. 



§ Annual : stems branched. — Kyberia, NecTc. 



1. B. integrifolia (Michx.) : stem diffusely branched ; leaves entire, sparse- 

 ly hairy and ciliate ; the radical and lowermost spatulate-obovale, scarcely 

 petioled ; the upper lanceolate or oblong, sessile ; peduncles elongated ; scales 

 of the involucre lanceolate-ovate, acuminate, with membranaceous margins; 

 achenia somewhat scabrous. — Michx. ! fl. 2. p. 131 ; Hook. ! hot. mag. t.

Along streams and in prairies, Kentucky ! Tennessee ! Arkansas! and Texas ! 

 March-June. — Stems 4-12 inches high. Heads about as large as the true Dai- 

 sy (B. perennis) ; the ray pale purple or violet. Scales of the involucre clothed 

 with scattered hairs, acuminate into a bristly point. Appendages of the style a 

 little longer than in B. annua. Rays pistillate, and apparently always fer- 

 tile. — This appears to be a true congener of Bellis annua, as Hooker has re- 

 marked. 



33. APHANOSTEPHUS. DC. prodr. b. p. 310. 



Heads many-flowered ; the ray-flowers pistillate; those of the disk tubu- 

 lar, perfect. Scales of the involucre imbricated in a double series, lanceolate, 

 acute or acuminate, with scarious margins. Receptacle conical, large, naked. 

 Rays linear, twice the length of the involucre ; the corolla of the disk tubu- 

 lar, 5-toothed, narrowed at the base. Branches of the style short, flat, termi- 

 nated by a very short obtuse flattened cone. Achenia terete, obscurely 

 striate, nearly glabrous. Pappus exceedingly minute, coroniform, nearly 

 entire. — Annual ? or perennial pubescent and branching (Mexican and Texan) 

 herbs. Leaves alternate, incisely toothed or lobed. Heads solitary, pedun- 

 culate, terminating the branchlets. Rays white. 



The genus should perhaps be removed to the Subtribe Anthemidese ; as De Can- 

 doUe has suggested. 



1. A. Riddellii: perennial; stems branched from the base, erect ; radical 

 and lower cauline leaves lanceolate-spatulate or nearly linear, acutely and 

 incisely toothed towards the apex, tapering below into a long and slender pe- 

 tiole ; those of the branches narrowly linear, entire, crowded. 



Texas, Dr. Riddell ! — Root ligneous, acrid to the taste. Stems ri.gid, slen- 

 der, 6-8 inches high ; the flowering branchlets slender, naked towards the 

 summit. Leaves minutely hirsute-pubescent and somewhat canescent. Heads 

 smaller than in BeUis integrifolia, but very similar in appearance. Recepta- 

 cle nearly the length of the involucre. — From A. ramosissimus, DC. this 

 species ajjpears to differ chiefly in its sharply toothed and conspicuously pe- 

 tioled lower leaves (those of the branches more crowded), and in the rather 

 larger flowers ; characters which are perhaps inconstant, and not of specific 

 importance.
