Willdenow, in his edition of Species Plantarum, has retained the 
four Linnean species of Calea, 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. | 
. The first of these additional species, taking them in the order 
in which Willdenow 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 dicecious genus with naked Sn celine pappas, 
and a habit nearly similar to that of Baccharis, of which Baccharis nereifolia Linn. 
- only published species. It may be named 
BRACHYLENA.
