 Misttlsua Cantoniensis, D.C. 

 JI. serrata, Hook.

f f Pappus consisting of copious capillary bristles in a single or more rows (rarely 

 depiiuperaie in the ray-achenes). 



X Ligules rather broad or ample. 

 Callisiephus, C'assini. 



Incolucre liemisplierical, the outer bracts leafy, tlio inner ones membranously 

 scarious. Achenes compressed. Outer bristles of pappus very short, and forming 

 a small crown. 



* C. (Astek) Chinensis, L. Cultivated. 



X J Ligules ntimerous, in 2 or more rows, narrow or almost filiform or minute. 



EitiGEHOx, Linnaus. 



Inrolucral bracts in 2 rows, narrow, somewhat une([ual. Achenes compressed. 

 Bristles of pappus in a single row, or with a few veiy short outer ones.

E. hispidum and lilumea puhifora, D.C. 

 E. suhlyratam., Roxb. 

 Conyza Jordoni, Clarke. 



The ligulate ray-florets seem to be sometimes absent, at least in dried specimens 

 they appear so. The Egyptian plant agrees in all parts with the Indian, but appears 

 to be often ray-less. 



Conyza angustifolia, Eoxb., appears from the description and MS. figure to be 

 a luxuriant form of E. Canadensis, L., or E. linijolius, Willd., and is, therefore, 

 hardly an Andamanese plant (Kurz). 



Sub-h-ibe SEXECIOXiniE,E. 

 Flower-heads either heterogamous, with tlie female florets ligulate or rarely filiform, 

 or sometimes homoganious, icith all the florets hermaphrodite and tubular. Receptacle 

 usually naked. Lnvolucral bracts usually in a single row, with or without outer small 

 ones, rarely in sereral rows and imbricate. Antliers obtuse or shortly 2-mucronate at 

 the base. Style-branches of the hermaphrodites truncate and penieillate, or rarely with 

 pubescent tips or appendages. Paj)pus of capillary bristles. Leaves alternate. 



X Flower-heads radiate or homogauwus. Bristles of pappus not feathery. 



Gtnuea, Cassini. 



Flower-heads homogamous. Style-branches tcnninating in an elongate shortly 

 hairy subulate appendage. Best as in Seneeio. Herbs, often tuberous-rooted. 



G. Nepale.vsis, D.C. Ava. Tenasserim at 4000 feet (P.). 



Pubescent. Leaves rather small, ovate to linear-lanceolate, repand-toothed, 

 acuminate. Peduncles and involucral bracts hoary pubescent. 



G. sixuata, D.C. Tsittoung Yalley. 



Pubescent, the root tuberous. Leaves more or less laciniate to pinnafifid. 

 Peduncles and involucral bracts less hairy. 



As long as it is young, the plant looks almost scapiferous and the leaves are then 

 simpler and smaller, but at the rate that the tuberous roots enlarge, the plant becomes 

 more robust, larger, and branched from the base witli the leaves up to 7 inches long 

 (Kurz).
