THE NURSER Y LIST. 207 



Imantophyllum. Amaryllidece. 



Seeds. Usually increased by division or by means of 

 bulbels. 



Impatiens, Balsamina (Balsam). Geraniacece. 



The common annuals may be raised from seeds, in spring, 

 in any ordinary light soil. The stove and greenhouse species 

 may be increased by seeds, or from cuttings, which root 

 freely in a close frame. /. Sultani does best from seeds. 



Indian Fig. See Opuntia. 

 Indian Shot. See Canna. 

 Indigofera (Indigo). Leguminosce. 



Propagated by seeds. Cuttings of young shoots may be 

 inserted in sandy or peaty soil under glass, in slight heat. 



Inga. Leguminosce. 



Propagated by seeds. Cuttings root with difficulty. 

 Inula, Elecampane. Composite*?. 



Readily increased by seeds or by divisions, 

 lonidium, Solea. Violariece. 



The herbaceous species are increased by seeds and by 

 divisions. The shrubby sorts are increased by cuttings 

 which will root in sand, in a frame. 



Ipomcea, including Quamoclit (Moonflower, Morning Glory) 



Convolvulacece. 



All the annual species are grown from seeds. The peren- 

 nials are also increased by seedage, but they may be raised 

 from cuttings struck in a forcing-house or a frame. The 

 moon-flowers often do better in the north from cuttings than 

 from seeds. /. Horsfalhce is largely propagated by layers, 

 and other species may be treated in the same way. Division 

 is sometimes employed. I. pandurala can be propagated by 

 root-cuttings. Also grafted (see page 88). 



Ipomopsis. See Gilia. 



Iresine, Achyranthes. Amarantacea:. 



Seeds rarely. Increased readily by cuttings. For sum- 

 mer bedding in the north, cuttings should be started in 

 February or March. For use as window plants, they should 

 be taken in late summer. 



Iriartea, Deckeria. Palmce. 



Propagation is effected by seech
