 Channel. Alyssum orbiculatum, D. Urv. Farsetia orbiculata, 

 Spreng. syst. 2. p. 870. Leaves and stems hoary with stellate

Orbicular-podded Berteroa. Fl.Jul. Aug. PI. 1 ft. decumbent. 



5 B. PERUVIA NA (D. C. syst. 2. p. 293.) pods ovate-oblong, 

 scabrous with small hairs ; pedicels bracteate. I/ . Jj . G. 

 Native of Peru in the coldest places. Farsetia Peruviana, Spreng. 

 Petals obcordate, twice the length of the calyx. Leaves and 

 stems scabrous with distant stellate hairs. 



Cult. As the species of this genus ripen seed in abundance, 

 it is the best method of increasing them. They only require to 

 be sown in the open border, but, however, young cuttings of the 

 shrubby sorts planted under a hand-glass will root freely. Not 

 worth cultivating except in botanic gardens.

Cult. These very ornamental plants thrive well in a dry 

 soil ; they are well adapted for ornamenting rock-work or 

 the front of flower-borders, where they will flower nearly all 

 the season ; they are readily increased by dividing the plants at 

 the root, or cuttings planted under a hand-glass will root readily ; 

 seeds also ripen frequently, by which they may be raised in 

 plenty.
