IXIA. (From ixia, bird-lime ; in reference to the

 Triandria, i-Monogynia.) 



Half-hardy bulbs, from South Africa. The true Ixias 

 are known from Spara'xis by not having, like it, a jagged 

 sheath ; from Babia'na, in having a dry seed-pod instead 

 of a berry ; and from Trito'nia, by having the stamens 

 inserted at the bottom of the petals instead of in the 

 tube of the flower. They will all grow in rough peat ; 

 the strong ones require very little sand, and the smaller 

 ones want one-third sand in the compost. They succeed 

 well in a warm border, if sheltered from hard frosts, 

 and not allowed to get dry when they are in growth. 

 By seeds sown in a little heat, in spring ; also by offsets ; 

 sandy loam, peat, and a little leaf-mould. When done 

 flowering, they may be kept in or out of the pots, after 

 the leaves get withered, without any water, until fresh 

 growth commences. They will generally require to be 

 potted in October, and should then be placed in a cold 

 pit, and protected from frost, and cold, heavy rains, and 

 taken to the greenhouse or window, after roots are 

 plentifully formed. Many will do very well if planted 

 in sandy soil and leaf-mould, about four inches deep, in 

 a dry, raised border, and protected there from severe 

 frost and heavy rains by litter, and any material that 

 will throw off the water.
