Willdenow, in his edition of Species Plautarum, has retained the 

 fourLinnean species of Galea, and added to them an equal num- 

 ber, not one of which belongs to any of the genera formed by the 

 original species, but to four others equally distinct. 



Tlie^rs^ of these additional species, taking them in the order 

 in which AVilldenow has arranged them, is Calea aspera, which 

 he adopted from Jacquin ; by whom it is well described and 

 figured, though erroneously referred to Calea. 



* I have observed another dioecious genus with naked receptacle, capillary pappus, 

 and a habit nearly similar to that of Baccharis, of which Baccharis nere'ifolia Linn, is 

 the only published species. It may be named 



BrACHYLjENA.
