Most of the plants of this genus deserve cultivating 
on account of their very pretty blossoms, which 
are produced in great abundance. The stove, 
greenhouse, and frame species, thrive well in a 
mixture of loam, peat, and sand ; they should not 
be watered after they have done flowering until 
they begin to grow afresh. The shrubby kinds 
may be increased by cuttings or seeds ; the her- 
baceous fibrous rooted ones by dividing the plants 
at the roots, or by seeds, the bulbous-rooted species 
by offsets. Most of those marked greenhouse may 
be grown in a frame, only they must be protected 
from frost in winter. The hardy species should be 
planted in a shady border, where they will grow 
and flower very freely'. The seeds of the hardy 
annual species should be sown in the open border 
in spring. O. Acetosella contains pure oxalic acid, 
and several species are used in Brazil against 
malignant fevers. Synonymes : \. caprina. 2.arra-
