house shrubs ; the species bicolor, huxifolia, pyrifolia, and 

 aggregata may be introduced with advantage ; the latter is 

 now sometimes known as Gillia aggregata, it has scarlet 

 flowers. 



COB^A. 



Gen. Char. (Pentandria Monogynia.) Calyx five-cleft, bell- 

 shaped, five-cornered and winged ; corolla bell-shaped, with five 

 blunt lobes ; stamens curved down ; filaments spiral ; capsule 

 obovate, from three to five-celled. 



A Mexican genus, named after Cobo, a Spaniard. C. scan- 

 dens, though now a hardy plant, is so well adapted as a 

 greenhouse climber, that it will not fail to be introduced ; 

 its leaves are pinnated, with a branched tendril at the point, 

 which is exceedingly amusing to watch, for whenever the 

 stem wants support this tendril uncurls, and stretches itself 

 out until it meets with something rough to cling to, there 

 it inserts the little appendages at the ends, and takes 

 fast hold; the beautiful bell-shaped flowers are large, at 

 first green, then purple, becoming deeper in colour till they 

 fall. The plant requires a rich sandy loam, and if favour- 

 ably placed will grow many feet in a season, sending out 

 side-shoots, which flower as well as the main stem. C.
