posed in a leafy panicle. $ . F. Native of Chili, in the Jarillal, 

 or uncultivated grounds between Mendoza and the mountains ; 

 generally by the side of dry water courses, at about 3000 feet 

 above the level of the sea. Sweet, fl. gard. new ser. t. 182. 

 B. sinuata, Presl. reliq. Haenk. 2. p. 38. Petals 10, pale yel- 

 low. Filaments all dilated. Stigmas 3-lobed. This species does 

 not turn black on drying, as in the other species, and is readily 

 distinguished from them by the beautiful white down on the stem. 



Hoary Bartonia. Fl. July, Sept. Clt. 1831. PI. 1 to 4 feet. 



Cult. The seeds of the species should be raised in a gentle 

 heat in spring ; and when the plants are of a proper size, they 

 should be potted separately in small pots, and shifted from size to 

 size of pots as they grow ; the pots should be well drained with 

 sherds ; and in the winter they should be placed on a dry shelf 

 in a greenhouse or frame. The flowers are very showy, and the 

 plants are therefore worth cultivating in every garden.
