 about the extremity of the shoots. Leaves oblong, bipinnatifid, stalked ; 

 with obtuse lobes, with winged, semiamplexicaul petioles. Peduncles 

 solitary, axillary, 1 -headed, shorter than the petioles. Heads hemi- 

 spherical. Florets yellow. Leaves considered by the Indian doctors 

 a valuable stomachic medicine; they are also sometimes used in anodyne 

 and antiseptic fomentations.

Stems with 3 decurrent leafy wings which are flat, veinless, short, or 

 frequently interrupted. Leaves very small, reduced to sharpish some- 

 what ternate scales. Heads 1-2, in interrupted spikes. Involucre 

 turbinate, with the scales all acuminate. Receptacle naked. Achasnia 

 smooth, subcylindrical, sulcate. This and B. venosa DC. y a nearly 

 allied species, are called in Brazil Carqueja dolce, and C. amarga. On 

 account of the quantity of bitter extractive matter which they contain, 

 and which is combined with a specific aroma, they are particularly 

 useful in all intermittent fevers, and for all disorders in which Artemisia 

 is employed in Europe. Both the extract and the decoction are used. 

 It is particularly serviceable in chronic diseases of horses, which are 

 very fond of this herb. Martins.
