in a greenhouse after its usual occupants are placed out of 

 doors. Most of these may be raised from cuttings, or made 

 biennial by removing all flower-buds the tirst year. Some of 

 them, if reared in a mild heat, and carefully inured to ex- 

 jDOSure, will flower out of doors in a moderately sheltered 

 situation ; but they require a moist atmosphere, and moisture 

 at the roots, as well as a warm exposure. I. glanduUfera , 

 I. macrochila, and /. Candida are the best for this treatment : 

 these have a fine pyramidal habit, and bloom abundantly. 

 The hardy annuals may be sown in the open border in a 

 dampish sheltered place, and there they \^ill spring up 

 abundantly from scattered seeds. See Balsamina for culture 

 of the stove annual kinds.

INDIGOFERA. Ixdigo. [Legnminosse, § Piipilionacece.] 

 An extensive genus, not of much importance in an ornamental 

 point of view, and on that account seldom cultivated. It 

 contains many stove shrubs and annuals, and also some 

 greenhouse shrubs, two or three of which latter are very 

 pretty objects. They are increased by cuttings in sand 

 under bell-glasses, or more easily by seeds when these are 

 produced. The young plants should be potted into a com- 

 post of turfy peat and loam in about equal parts, sand being 

 added to render it porous : they must not be over-potted, 

 but shifted only as their roots thicken into pots a size, or at 

 most two sizes larger. In other respects they require the 

 usual attention bestowed on greenhouse plants. They are 

 very liable to the attacks of red spider. I. decora is the 

 best, but there are many others. 



INGA. [Leguminosae, § Mimoseae.] Very beautiful stove 

 shrubs. Peat and loam. Propagated by cuttings in sand 

 under a bell-glass, and placed in a brisk bottom heat ; some- 

 times by seeds. They require brisk heat in summer while 

 growing, and afterwards to be kept cooler and drier. 



lOCHROMA. [Solanaceae.] Greenhouse shrubs, allied 

 to, and with the habit of, Habrothamnus. Rich sandy loam 

 and peat. Increased by cuttings of the half- ripened shoots
