 alternate leaves. Capitula large. Involucre irregularly 

 imbricated. Receptacle flat or convex. Corolla of the 

 disk short, throat dilated. Flowers yellow. [This genus 

 scarcely merits a place in the Indian Flora, but as it is 

 every where cultivated and is supposed by many to be 

 an Indian plant^ I have introduced it here.]

 with opposite leaves, peduncles 1-cephaIous. Capitula 

 ovate or conical. Involucre adpressed, 2 series, shorter 

 than the disk, exterior ones foliaceous. Flowers yellow.

 especially in shady places and in alpine or sub-alpine 

 pastures.

 leaves. Petioles winged and auricled at the base. 

 Capitula loosely corymbose. Receptacle convex, palea- 

 ceous. Paleae membranaceous, lanceolate. Flowers 

 yellow, [D. C. seems not to regard this as an Indian 

 genus: but as I have, apparently, native specimens, 

 which may however have been introduced, I give it 

 a place in this list] Palamcotta.
