The tuberous rooted kinds, or those belonging to 

 sections Hodrea, Dimacria, and Seymoiiria thrive best in an 

 equal mixture of light turfy loam, peat, and sand ; and when in 

 a dormant state, require to be kept quite dry, which commences 

 as soon as they have done flowering, and have ripened their 

 VOL. i. PART. vin. 



seeds ; after which time they require to be kept in a cool situ- 

 ation, out of the reach of frost, but as soon as they begin to 

 push afresh, all the old mould should be shaken out of the pots, 

 and from their roots ; they should then be potted afresh in new 

 mould. In potting them care must be taken not to bury the 

 heart of the plants ; after this they require a little water, and, as 

 they grow, watered whenever they are dry, and if the pots get 

 filled with roots they must be shifted into larger ones. The 

 best method of increasing them is by the little tubers, which issue 

 from the old bulbs, planted singly in small pots, with their tops 

 above the surface, and kept dry until they begin to grow, when 

 they should be watered. The commoner, free growing, shrubby 

 kinds will thrive well in a rich loamy soil, or a mixture of loam 

 and decayed leaves. The dwarfer woody kinds, as P. tricolor, 

 elegans, and ovale, thrive best in a mixture of loam, peat, and 

 sand ; the pots should be well drained with potsherds. The 

 fleshy stemmed sorts succeed best in rather more than one-third 

 of fine sand, the same quantity of turfy loam, and the remainder 

 of peat ; the pots also require to be well drained with pot-sherds, 

 very little water is requisite when they are not in a vigorous state. 

 Young cuttings of all the shrubby kinds strike root freely under 

 hand-glasses, in the same kind of soil recommended for the 

 plants, or in pots without being covered by glasses, placed in a 

 shady situation. Many of the kinds may be increased by slips 

 from the roots. No genus is more liable to sport into hybrids 

 than Pelargonium by promiscuous impregnation. All the fine 

 hybrid varieties in the gardens have been obtained by impreg- 

 nating one sort with the pollen of another, by cutting out the 

 anthers of the plant intended for the female parent before they 

 burst, and impregnating the stigmas with the pollen of another. 

 The object of this should be to obtain a superior variety ; there- 

 fore particular attention should be paid to those plants intended 

 for the parents, and more so to that intended for the male parent ; 

 for it has been observed that seedlings approach nearer to the 

 male than the female parent. To grow geraniums in rooms, 

 they require as much air and light as can possibly be given 

 them, and watered regularly when dry ; and when the leaves get 

 dusty, to clean them well with a sponge and water.

 aspect of plants). Lin. gen. 1235. Gaert. fruct. 1. p. 180. t. 36. 

 Sweet, ger. 171. D. C. prod. 2. p. 549. 



LIN. SYST. Monadelphia, Decandria. Calyx permanent, 5- 

 cleft, with a short tube, rather concrete to the carpels. Petals 

 5, inserted in the tube of the calyx. Stamens 10, connate at 

 the base ; filaments permanent. Styles 5-10, short, capitate. 

 Capsule of 5-10 closely concrete carpels, depressed at the apex; 

 carpels verticillate, 1- celled, 1 -seeded. Seeds inverse. Coty- 

 ledons leafy. Radicle oblique, superior. SufFrutescent herbs, 

 natives of the Cape of Good Hope, with dissected leaves, and 

 large, solitary, axillary flowers. It is doubtful whether this 

 genus really belongs to Geraniacece ; the habits of the plants are 

 like those of Monsbma, but the structure of the fruit and the 

 seeds come nearer to Neurada ; both genera perhaps more 

 properly belong to Malvacece, but De Candolle has placed them 

 in Rosacece, where they form a separate section, called Neuradece.
