434 SYNGENESIA FRUSTRANEA. 



This species appears to differ much in size^ and somewhat in habit, and 

 may require further comparison. The plant which I have described above 

 I collected around ponds a few miles from Darien, along the road to Fort 

 Barrington. The pappus, as in the Hehanthus, appears to be an appendage 

 slightly attached to the seed, and diflTering from the pericarp in substance 



and colour. 



In the C; Lanceolata as figured by Dillenius, (Hort. Elth. t. 48. f. 56.) 

 the plant is altogether larger, and the lowest leaves have long attenuated 



bases* - 



Grows in damp soils. , . 



■ Flowers April— May; perhaps through the summer. (August— October,

Root perennial. Stem about two feet high, sparingly divided at base, 

 striate, hairy below the upper pair of leaves. Leaves few^ opposite, oblong, 

 narrow, the lower attenuated at base, forming a petiole one to two mches 

 long, very hairy. Flotcers solitary, terminal. Involucrum nearly equal, 

 glabrous. Florets of the ray about eight, bright yellow, dilated and toothed 

 at the summit. ^ 



The leaves of this species though thicker than those of C. Lanceolata, 

 scarcely merit the character of crassifoliaj liirsuta would have been a more 

 appropriate appellation. 



Grows in pine barrens, in soils rather dry. 



Flowers June —
