of floral leaves : the true calyx is composed of three leaves, 

 which are nearly white : the two outer petals are similar to the 

 wings of a papilionaceous flower, and are also white, or nearly 

 so ; the third petal, which forms a kind of tube and contains 

 the stamens and pistils, is white at the base, but yellow towards 

 the extremity, where it changes by degrees to a bright bay 

 colour. Filaments four on each side, slightly united at the 

 base. 



The whole of the Polygala tribe is interesting : — of those 

 which are hardy, some are herbaceous perennials, others are 

 annuals. The Chamcebuxus was introduced into England in 

 1658, and is the only hardy shrub in the genus: when culti- 

 vated, this shrub rises.with branches from nine inches to a foot 

 in height ; in a wild state it does not grow so high. 



It is a native of Austria, Germany and Switzerland, where 

 it grows spontaneously on the mountains, flowering plentifully 

 in May, and partially until August. It thrives well in light 

 mould : in peat or bog- earth it flourishes. 



This shrub, — hitermixed with GauUheria procumbens, Mit- 

 ch'ella repens, Linnaea borealis, and other dwarf-growing shrubs, 

 — will greatly enrich the front of American beds, where it will 

 grow luxuriantly, forming a close and ornamental bush. It 

 may be propagated by separation, as it throws up numerous 

 branches from the ground, which may be taken off* with roots 

 in the month of April.
