XIX. COMPOSITE. Syngenesia of Linnffius. 



In this class, I have adopted the following Orders, instead of exactly following Linneeus : — 



I. Plorets all ligulate. Branches of the style convex, everywhere pubescent. LiGULATiE, or 



Cichoracece. This, and most of the Cynaa'cse, ybrm the Syngenesia ^qualis of Linn. 



II. Central Florets tubular ; outer ligulate. RADiATJi;, or Corymbiferce, forming, with the 

 Discoidese, Syngenesia suPEnrLUA of Linn. 



ill. Florets all tubular ; but the outer without stamens. Style without a joining. Discoide^. 



IV. Florets aU. tubular. Stigma with a marked joining on to the style. Cynarocephala, or 

 Cynake^. Of these, the Tribe Centauriese belongs to the Syngenesia frustranea of 

 Linn. The Xeranthemese are' included in his Syngenesia superflua ; the Echinop- 

 sidese in Syngenesia segregata. 



V. Central Florets tubular ; outer ligulate. Stigma with a marked joining on to style. Ca- 

 LENDULACEiE. Included by Linnceusin Syngenesia necessaria. 



YI. Antheriferous and style-bearing Fl. distinct. Anthers free. This division will be found 

 in Moncecia Pentandria. Ambrosie^. 



Order I. LIGUZiATii:. 



The Tribes are — 



1. Catananche^. Stigmas ovoid. Receptacle fibriUose. Gen. 381. 

 In aU the other tribes the Stigmas are cylindrical or semicylindrical. 



2. ScoLYMEiE. Seeds invested with the chaff of the receptacle. Gen. 382. 

 In the other tribes the Seeds are free. 



3. Lapsane^. Crest of the Seeds 0, or a mere margin. Receptacle naked. Gen. 383-386. 

 ■ 4. HYOsERiDEiE. Crcst chaffy. Receptacle naked. Gen. 387-390. 



5. Hypochceride^. Crest, of the inner Seeds at least, feathery. Receptacle chafiy. Gen. 

 . ' 391-395. 



In the four following Tribes the Crest is feathery, and the Receptacle naked ; — 



6. TeagopogonejE. Cal. simple, without accessory Scales. Gen. 396-398. 



7. LEONTODONTEiE. Cal. simple, but with accessory Scales. Gen. 399-402. 



8. PicaiDEiE. Cal. double. Gen. 403, 404.
