volucral bracts imbricate, in about 2 series. Receptacle convex or nearly flat, 

 naked. Achenes compressed, obovate-oblong, suddenly narrowed into a short 

 beak at the top. Pappus none. — Small herbs. Leaves radical or on very 

 short stems. Scapes single-headed. 



A genus of about ten species, natives of the south temperate zone and chiefly Austraha, . 

 one only inhabiting also southern and eastern Asia. 



1. L. Billardieri, Cass. ; BO. Prod. v. 307. Eoot-stock emitting se- 

 veral thick, almost tuberous, cylindrical fibres. Leaves radical or on a very 

 short stem, oblong or obovate, sinuately toothed, pubescent, seldom above 1 

 in. long. Scape slender, 3 to 4 in. high, often with 1 or 2 minute scale-like 

 leaves. Flower-head scarcely 2 lines diameter. Involucral bracts linear. 

 Rays very small, in 2 or 3 rows. Achenes obovate-oblong ; the beak slightly 

 glandular. — Bellis stipitata, Labill. PI. Nov. HoU. t. 205. L. sundana, Miq.

Hongkong, Champion, WrigJit. A native of south-east Australia, found also in Ceylon, 

 eastern Bengal, the Archipelago, and China. I have little doubt that this is Labillardiere's 

 plant, and it should therefore retain Cassini's name in preference to that of L. paekyrhiza, 

 given it by 1\ Miiller. The purely Australian form, with a much larger flower-head and 

 broad achenes, more particularly described by J. D. Hooker (Fl, Tasm. i. 188), may be a 

 distinct species. 



9. DICHROCEPHALA, DC. 



Plower-heads heterogamous. Plorets all tubular, those of the circumference 

 in many rows, female, smaU and slender, those of the disk hennaphrodite, with 

 campanulate corollas. Involucral bracts smaU, in 1 or 2 series. Receptacle 

 very convex, naked. Style-branches in the disk-florets lanceolate, pointed. 

 Achenes flattened, bordered with a callous margin. Pappus none, or in the 

 disk consisting of a few minute haii'S. — Branching herbs. Leaves alternate. 



A genus of a very few S. Asiatic, or African, or Austrahan species. 



1. D. latifolia, BC. Prod. v. 372; Wight, Jc. ^. 1096. An erect or 

 spreading annual, 1 to \\ ft. high, pubescent or nearly glabrous. Leaves 

 stalked, undivided or lyrate ; the terminal lobe broadly ovate, coarsely toothed. 

 Plower-heads few, veiy smaU, nearly globular, forming short terminal divari- 

 cate panicles. Plorets very numerous and minute. — B. capensis, DC. 1. c. 371, 

 and B. sonchifolia, DC. 1. c. 372. 



Hongkong, Hance. A common weed in the warmer parts of Asia and Africa, extending 

 northward to Loochoo, eastward to the Archipelago, and southward to Port Natal. 



10. BOLTONIA, L'Her. 



Plower-heads, involucres, and florets of Aster. Receptacle veiy convex^ or 

 conical. Style-branches flat ; the appendages lanceolate or triangular. Achenes 

 of the disk veiy flat, with a prominent callous or wing-hke marghi, those of 

 the ray often 3-angled. Pappus of several minute setose or almost chafty 

 bristles, 2 or 3 (seldom 4) of them elongated into short stiff awns, and all 

 often very deciduous. — Perennial, glabrous or scabrous, paniculately branclied 

 herbs. Leaves alternate. 



A small genus, chiefly N. American, with two or three E. Asiatic species, including 

 Calimeris incisa, DC. {Heteropappus, Zucc), but not the other species of Calimeris known to
