20 FLORA OF SOUTH AMERICA AMD THE PACIFIC. 



corolla, is a mere gibbosity; it becomes therefore difficult to say ' 

 whether it ousjht not to be considered as a lifjulate floret, in 

 which case the genus would rank next to Solenogyne; but 

 considering that the central florets are sterile, we prefer 

 placing it near Dichrocephalus {Cmtipeda^ Less.), and Gran- 

 gea, with which it agrees much in habit. 



Professor De Candolle has adopted this Genus, which was 

 communicated to him in mst. and has placed it in the " Com- 

 posite Senecionidea" adding a second species, thus : — 



(1. P. tanacetoides {Hook, et Arn.) ; erectus ramosus pilo- 

 sulus, foliis interrupte pinnati-partitis basi amplexicauli- 

 auriculatis partitionibus inciso-serratis, capitulis corymbosis. 



2. v. soliv(^formis, (DC); glabriusculus demissus ramosus 

 repens, foliis petiolatis pinnati-partitis, partitionibus lineari- 

 bus parce lobatis, ultimis apice trilobis, capitulis solitariis 

 longe pedicellatis. — Hab. in Republica Bolivaria. Pentland. 

 Pili parcissimi secus ramos et folia novella sparsi. Achenia 

 parce glandulosa glabra. (DC.) 



1040. (I.) Conyza Chilensis, Spr.~DC. Prodr. \. p. 378. 

 — C. longifolia, Cass. — Chili. Bridges (n. 624.). Maldonado 

 and Entro Rios. Ttveedie (n. 1077.) — To tliis, and not to 

 C. albida, we are inclined to refer Erigeron Bonariense, Linn. 

 and Dill. Hort. Elth. t. Ibl, f. 334, in bud ; although De 

 Candolle considers that a species of Erigeron with which he is 

 unacquainted. 



1041. (2). C. albida, TVilld. DC. Prodr. v. p. 378 Eri- 

 geron Canadense, Don, Mst. (non Linn.). E. tramontanus. 

 Gill. mst. — Mendoza. Gillies, (n. 156). Buenos Ayres and 

 North Patagonia. Ttveedie. Valparaiso. Bridges, (n. 987). 

 C. linearis, DC. Prodr. v. p. 378, is our Erigeron stenopJujllus, a. ; 

 and our Conyza ambigua, Bot. of Beech. Voy. p. 57, is an 

 imperfect state of our E. spiculosus. — See our observations on 

 Erigeron and Conyza, in Comp. Bot, ^lag. v. ii. p. 254. 



1042. (3.) C. diversifolia, (Weinm, in Flora, 1820, p. 611); 

 herbacea ad coUum sufFruticosa erecta tota villoso-cinerea, 

 caule simplici pilis eonfertissimis hirsuto, foliis pube breviori 

 velutino-villosis sublus hirsulis eionfrato-iinearibus acutis,
