Aster.'] COMPOSITE. 175 



or in ib.6 Hongkong specimens mostly obtuse, coarsely toothed, narrowed at 

 the base, the lower ones stalked, all very scabrous, and occasionally pubescent 

 underneath, usually triplinerved. Panicle terminifil, corymbose, rather loose, 

 the peduncles mostly about the length of the heads. Involucre hemispherical 

 or subcamptoulate, the bracts all obtuse and thin on the edges, in 2 or 3 rows. 

 Style-appendages narrow. Achenes flat, hairy. Pappus rusty-coldnr, a few 

 of the bristles very much shorter than the otheta.-^Liplopappus asperrimm,

On rather barren hills, OAampion; Mount Gongh, Wilford; also Eance. IVeqnent in 

 N. India, from Nepal to Sikhim and Khasia, extending in China to Shanghai and Chnsan. 



3. A. \ivevipeSfBenth.,n.sp. An erect branching perennial or undershrub. 

 Leaves oblong or dljovate, more or less toothed, obscurely tripUnerved and 

 scabrous, more like those of A. trinervkis than of A. haccharoide». Flower- 

 heads as in the latter species, few, on short peduncles or nearly sessile at the 

 ends of the branches, and turbinate-campanulate ; but the involucral bracts 

 differ from both species in being all acute. Pappus of A. baccharoides. 



Hongkong, Wright ; and a fragment in Champion's collection. It is possible that bett^ 

 specimens may show it to be a remarkable variety of A. baccharoides. 



4t. A. baccharoideS) Steetz in Seem. Bot. Her. 385. Stem shrubby 

 at the base and branching. Leaves rather crowded, oblong-lanceolate to 

 obovate-oblong, entire or slightly toothed, narrowed at the base, triplinerved, 

 very scabrous on the upper side. Plower-heads few, sessile or on very short 

 peduncles, crowded at the summit of the branches. Involucre turbinate-cam- 

 panulate ; the bracts numerous, in several rows, obtuse, thin at 'the edges. 

 Style-app^nd^ges broadly lanceolate. Achenes flattened, hairy. Pappus dirty- 

 white, the short outer bristles very few or sometimes none. — Diplopappus 

 baccharoides, Benth. in Lorid. Joum. Bot. i. 487, and in Kew Joum. Bot. iv.

Abmidant on barren hills in the island. Also on the adjacent continent, but not known 

 out of S. China- 



12. EEIGEROUr, Linn. 



Plower-heads heterogamous. Florets of the ray ligulatci in several -series, 

 not yellow, very narrow, either longer than the involucre and erect or spread- 

 ing, or shorten and filiform. Disk-florets numerous or few, hermaphrodite. 

 Involucral bracts numerous, narrow, in 1 or 2 nearly equal series, or rarely 

 imbricate, in several unequal series. Eeceptacle flat or slightly convex, not 

 chaffy. Style-branches narrow, the appendages lanceolate. Achenes com- 

 pressed, usually pubescent Pappus of copious capillary nearly equal bristles. 

 — Herb|, Leaves alternate or radical. Heads corymbose or paniculate, 

 rarely solitary, usually smaller than in Aster. 



A. large genus, ranging over the greater part of the globe, but chiefly in the temperate re- 

 gions of the northern hemisphere. The following species belong to a section {Cisnotus) in 

 which the very slender female florets are hid in the pappus, either all really ligulate or the 

 inner ones, intermediate between the outer ligulate florets and the disk, aie tubular and fili- 

 form as in Cony fa. This section includes some other weeds of warm countries which may 

 possibly introduce themselves into Hongkong, espeoiaDy the K canadense and E. tonarienae.
