246 Mr. D. Don's Descriptions of new Genera and Species 



series, will constitute perhaps another section. The Chaptalia 

 maxima of the Prodromus Flora Nepalensis has been improperly 

 referred by me to this genus, being really a species of Perdicium, 

 as constituted by Lagasca and DeCandolle. The Chaptalia run- 

 cinata of M. Kunth having the centre florets with a regular five- 

 cleft limb appears to belong more properly to the following 



oenus. 



Onoseris. Dec.

Atractylidis sp., L. 



Flosculi periphcerice fceminei, radiati, bilabiati ; disci hermaphro- 

 diti, tubulosi : limbo regulari, 5-fido. 



Involucrum hemispheericum, triplici ordine polyphyllum, imbri- 

 catum. Receptaculum nudum. Flosculi radii fceminei, bi- 

 labiati, staminibus sterilibus ; labio exteriore maximo, ligu- 

 lato, tridentato ; interiore tenuissimo, saepius bipartite, spi-

 persistens : radiis duplici ordine digestis, denticulato-sca- 

 bris.
