Lagenophora.'l composite. 173 



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

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

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

 short stems. Scapes siugle-headed. 



A genus of about ten species, natives of the acutlx temperate zone and chiefly Australia, 

 one only inhabiting also southern and eastern Asia. 



1. L. Billardieri, Cass. ; BO. Prod. v. 307. Koot-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. Mower-head scarcely 2 lines diameter. Involucral bracts linear. 

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

 glandular. — Bellis stipiiata, LabiU. PL Nov. HoU. t. 205. L. sundana, Miq.

Hongkong, Champion, Wright. A native of ?outh-east Australia, found also in Ceylon, 

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

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

 given it by F. MiiUer. The purely Australian form, with a much larger flower-head and 

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

 distinct species. 



9. DICHROCEPHALA, DC. 



Flower-heads heterogamous. Florets all tubular, those of the circumference 

 in many rows, female, small and slender, those of the disk hermaphrodite, with 

 campanulate corollas. Involucral bracts small, in 1 or 2 series. Heceptacle 

 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 hairs. — ^Branching herbs. Leaves alternate. 



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



1. D. latifolia, DO. Prod. v. 872; Wiglt, Ic. t. 1096. An erect or 

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

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

 Flower-heads few, very small, nearly globular, forming short terminal divari- 

 cate panicles. Florets very numerous and minute.— jD. capensk, DO. 1. c. 371, 

 and D. sonchifolia, DC. 1. c. 373. 



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

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



10. BOLTONIA, L'Her. 



Flower-heads, involucres, and florets of Aster. Eeceptacle very convex or 

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

 of the disk very flat, with a prominent callous or wing-Uke margin, those of 

 the ray often 8-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 branched 

 herbs. . Leaves alternate. 



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

 ■Valimeris inoisa, DC. {Heteropappiis, Zucc), but not the other species of Calimem known to
