Peruv. ill. Baccharidis species Linn. 
Involucrum imbricatum. Receptaculum nudum. Flosculi tubulosi, 
dioici. Masculi: antheris exsertis, basi muticis; stigmatibus ap- 
pendice acuto hispidulo; pappo subpenicillato. Feminei fili- 
formes; pappo capillari. 
Frutices (Americae aequinoctialis et temperatse). Folia alterna, 
raro opposita, in quibusdam minuta vel nulla, ramis tunc foliaceo- 
alatis. Inflorescentia terminalis rariusve lateralis, corymbosa, 
nunc fasciculata. Involucri subovati v. oblongi squamce semisca- 
riosce, margine simplici. Mas. pappo cinereo. Fein, limbo minuto 
2-3dentato, staminibus sterilibus nullis : pappo elongato*. 
Willdenow, in his edition of Species Plantaruin, 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 dioecious genus with naked receptacle, capillary pappus, 
and a habit nearly similar to that of Baccharis, of which Baccharis nereifolia Linn, is 
the only published species. It may be named 
BrACHYLjENA. 
Involucrum imbricatum, squamis coriaceis. Receptaculum nudum. Flosculi dioici. Mas¬ 
culi : antheris exsertis, basibisetis. Feminei angustiores, limbo 5-fido jj filamentis steri¬ 
libus : stigmatibus linguiformibus imberbibus. Pappus utriusque sexus pilosus scaber. 
Arbusculae vel Frutices (Africae australis) sultomentosi. Folia alterna integerrima vel 
dentata. Inflorescentia terminalis, sulracemosa. Involucra sulovata, Irevia : squamis 
ovatis, textura uniformi.
