172 coMPOsiTiE. [Mpatorium. 



A very large American genus, with a few Asiatic species, one of which extends also over 

 Europe. 



Leaves mostly ovate. Involucral bracts obtuse. 



Stem flexuose. Leaves rounded at the base 1. ^. Reevesii 



Stem erect and strict. Leaves narrowed at the base 2. ^. Jfallichii. 



Leaves mostly linear. Involucral bracts acute %. E. Lindleyanum. 



1. E. Reevesii, Wall.; DC. Trod. v. 179. Branches flexuose, slightly 

 pubescent. Leaves opposite, shortly stall<ed, ovate, more or less coarsely 

 toothed, rounded or slightly cordate at the base, glabrous or nearly so. Flower- 

 heads in compact terminal cymes, each head containing 5 or 6 florets. Invo- 

 lucral bracts about 10, very imequal, oblong, obtuse, thin and dry at the edges. 

 Achenes sKghtly hairy. — E. chinen&e, Thunb. M. Jap. 308, and Linn. ? 



Hongkong, Champion. This is undoubtedly the same as the Loochoo plant gathered by 

 Beechey and afterwards by Wright, and I agree with A. Gray that it answers to Thunberg's 

 description of his E. chhiense, but De Candolle gives that name to a plant with acute invo- 

 lucral bracts. It is possible that the present species may prove to be a variety of the follow- 

 ing, E. Wallichii. 



2. £S. Wallichii, DC. Prod. v. 179. Boot-stock perennial. Stem erect, 

 strict, and slightly pubescent, usually 2 or 3 feet high. Leaves like those of 

 E. Reevesii, except that they are always naiTOwed or wedge-shaped at the base. 

 Flower-heads of E. Reevesii, but the involucral bracts are usually fewer, and 

 there are occasionally only 4 florets. Achenes usually glabrous. — E. Pundua- 

 nmn. Wall., and E. nodijlorum. Wall., DC. 1. c. 



Hongkong, Uarland. I saw a single specimen of what appeared to me to be this species 

 in his collection, but have not now an opportunity of comparing it with those from the adja- 

 cent continent which I now describe. It is common in the mountain districts of Nepal, 

 Khasia, and Sikkim, and is also Fortune's n. A. 30 and A. 41 from Amoy. It is very closely 

 allied to the undivided-leaved varieties of the widely spread E. cannahinum. 



3. E. Lindleyan-um, I>C. Prod. v. 180. Stem erect, nearly simple, 

 1 to \\ ft. high, more or less pubescent. Leaves nearly sessile, linear or 

 linear-oblong, obtuse, toothed, 1 to \\ in. long. Flower-heads with 5 or 6 

 florets in each, in a compact terminal cyme ; the leaves at its base small and 

 few. Involucral bracts about 10, veiy unequal, as in E. Reevesii, but acute 

 or acuminate, especially tbe inner ones. Achenes slightly haiiy. 



Victoria Peak, Champion, Hance, Seemann, IFright. Also in the Philippine Islands, 

 Chiming; in E. Tartary, Har land; and A. Gray refers to it also the E. hyssopifolium, 

 Thunb. (not Linn.), from Japan. 



Tribe IV. ASTEROIBEM 



Leaves alternate or very rarely opposite. Flower-heads either heterogamous 

 or dioecious ; the female florets ligulate or filiform, the hermaplu'odite or males 

 tubular and 4- or 5 -toothed ; or very rarely the heads are discoid, with all 

 the florets hermaphi'odite. Style not swollen above ; the branches in the her- 

 maphrodite florets flat or flatfish ; the stigmatic lines conspicuous and not 

 confluent. 



8. LAGENOPHORA, Cass. 



Flower-heads heterogamous. Ray-florets ligulate, in one or few series, 

 spreading, not yeUow. Disk-florets numerous, hermaphrodite, tubular. In-
