=Caliphruria.= _Amaryllideæ._ Propagated by bulbels. After flowering, the plants should have a slight heat, and when starting into new growth should be repotted. =Calliandra.= _Leguminosæ._ Increased by cuttings of rather firm young wood, in sand under a hand-glass, in heat. =Calla.= See Richardia. =Callicarpa=, Porphyra (French Mulberry). _Verbenaceæ._ Propagated by seeds, divisions or by cuttings of the young shoots, with the same treatment as Fuchsia. =Callichroa.= _Compositæ._ Increased by seeds sown in spring in a slight hot-bed, and placed in the open border later; or if sown out-doors it will still flower in the autumn. =Callicoma.= _Saxifrageæ._ Propagated by half-ripened cuttings, placed in sandy soil under a hand-glass. =Calligonum=, Pallasia, Pterococcus. _Polygonaceæ._ Increased by cuttings, which will root in spring or autumn if placed under a hand-glass. =Calliprora.= _Liliaceæ._ Propagated by offsets, which should not be removed from the parent bulbs until they are of good size. =Callipsyche.= _Amaryllideæ._ Propagated by seeds and bulbels. =Callirhoe= (Poppy-Mallow). _Malvaceæ._ Perennials by seeds, divisions of roots, and cuttings; the annuals by seeds only. Cuttings should be started in sandy soil in a frame. =Calliopsis.= See Coreopsis. =Callistachys.= See Oxylobium. =Callistemon.= _Myrtaceæ._ Increased by seeds, and by ripened cuttings in sand under a glass. =Callistephus=, Callistemma (China Aster). _Compositæ._ Propagated by seeds, which should be sown under cover in spring, or seeds for late plants may be sown in the open. =Callitris=, Frenela. _Coniferæ._ Increased by seeds, or by cuttings inserted under a hand-light in autumn, and wintered in a cold pit. =Calluna= (Heather). _Ericaceæ._ Propagated by cuttings of the tender shoots inserted in pure sand under glass in a cool house in autumn. =Calochortus= (Mariposa Lily). _Liliaceæ._ Propagated by seeds, offsets, and by the tiny bulblets on the upper portion of the stem. Sow seeds as soon as ripe, or early in the year, thinly in pans, so that the young plants may pass a second season in the seed pots on pans. Place in a cool house or frame, and keep the plants close to the glass during their early stages, as they are very liable to damp off. Early the third season pot off and plant singly, encouraging them to grow freely. The offsets are best removed when the plants are in a dormant state, placed in pots or pans, or planted out in pits or frames until they reach flowering size. =Calodendron.= _Rutaceæ._ Increased by cuttings of half-ripened wood placed in sand under a glass, in gentle bottom heat. =Calophaca.= _Leguminosæ._ Propagated by seeds. May be grafted on the common laburnum. =Calophanes.= _Acanthaceæ._
