ILEX IPOMCEA. 257 



sorts are also increased by seeds sown in spring, but 

 more often by divisions or by cuttings. 



Ilex, including Prinos ( Holly). Ilicinece. 



Seeds, which should be stratified. They are often 

 cleaned of the pulpy coat by maceration. The seeds 

 rarely germinate until the second year. Varieties are 

 perpetuated by graftage. The veneer-graft, upon potted 

 plants, is usually employed, but other methods may be 

 successful. Budding is sometimes performed. 



Illicium (Aniseed-tree). Magnoliacece. 



Seeds. Cuttings of young ripened shoots may be made 

 during summer and should be placed in sandy soil, under 

 a glass. 



Imantophyllum. Aviary llidacea . 



Seeds. Usually increased by division or by means of 

 bulbels. 



Impatiens. See Balsam. 

 Indian Corn. See Maize. 

 Indian Fig. See Opuntia. 

 Indian Shot. See Canna. 

 Indigofera (Indigo). Leguminosa. 



Propagated by seeds. Cuttings of young shoots may 



be inserted in sandy or peaty soil under glass, in slight 



heat. 



Inula, Elecampane. Composites. 



Readily increased by seeds or by division. 



lonidium, Solea. Violacetz. 



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. 



Ipomoea, including Quamoclit (Moonflower, Morning Glory). 

 Convolvulacece. 



All the annual species are grown from seeds. Seeds of 

 moonflowers should usually be filed or cut on the point, 

 and started in a rather high temperature. The perennials 

 are also increased by seedage, but they may be raised 

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

 moonflowers often do better in the north frorr\ cuttings
