OxALIDACEffi, OXALIDS, or WoOD-SORRELSl 

 Herbaceous plants, nndershrubs, and trees, 

 containing a large quantity of acid. Some of 

 the species of Oxalis have large tuberous roots, 

 which are eatable like the potatoe ; some of * 

 the shrubby kinds, as Averrhoa Bilimbi, and 

 Carambbla, bear very grateful fruit, and are 

 called in the East Indies Blimbing and Ca- 

 rambola. The leaves of some species are so 

 sensitive that they are included amongst what 

 are called sensitive plants. 



Oxalis, Linn. From oxys, acid ; the leaves 

 have an acid taste. Linn. 10, Or. 4, Nat. 

 Or. OxaHd&ceoz. 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 

 herbaceous 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
