 natis, apice simplici setaceo, brevi : ramnlis persistentibus. 

 Obs, — I'abula Lamarckiana, errors pictoris, tubum antherarum 

 pro corolla exhibet. 



- I have, without hesitation, united the Chuquiraga insignis and 

 microphylla , being full}' persuaded that the characters relied on, 

 as marks of distinction, are of too transitor}'^ a nature to justify 

 the separation of two plants otherwise so much alike. In the 

 Lambertian herbarium are two specimens of C. insignis from 

 M. Bonpland himself, with the branches thickly clothed with 

 short hairs, and the young leaves slightly villous, which cir- 

 cumstances are regarded by him as constituting the specific 

 distinction of his C. microphylla ; but, as the epidermis is de- 



^ ciduous.
