 Nat. ord., Leguminous Plants [Faba-

 (jynla. Allied to Oxylobium.) 



Greenhouse evergreen shrub. Cuttings of 

 the young shoots when getting a little firm, in 

 sand, over sandy peat, and covered with a bell- 

 glass, in June ; sandy peat with a little fibry 

 loam, pieces of charcoal, and broken crocks ; 

 drainage and watering must be particularly 

 attended to. Winter temp., 40 to 48 ; summer, 

 a shady place, or a cold-pit, where the plant 

 partly, and the pot wholly, are sheltered from 

 the sun's rays.

I'xiA. (From ixla, bird-lime; in 

 reference to the clammy juice. Nat. 

 ord., Irhls [Iridaceie]. Linn., 3-Trhut- 

 ilria 1 -Monoyyn la. ) 



Half-hardy bulbs from the Cape of Good 

 Hope. The true Ixias are known from Spariueis 

 by not having, like it, a jagged sheath ; from 

 Habiana, in having a dry seed-pod instead of a 

 berry; and from Tritoniu, 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 aje 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, ana should then oe placed 



i in a cold-pit, and protected from frost, and cold 



i heavy rains, und taken to the greenhouse or 



| wind'ow, after roots are plentifully formed. 



i Manv will do very well if planted in sandy soil 



I and leaf mould, about four inches deep, in a dry 



I raised border, and protected there from severe 



j frost and heavy rains, by litter, and any material 



i that will throw off the water.
