320 THE NURSERY-MANUAL 



Gleditsia (Honey Locust). Leguminosae. 



Seeds should be sown in spring about 1 inch deep. They should 

 be soaked in hot water before being sown. Varieties are prop- 

 agated by grafts on seedling stock in spring, G. triacanthos being 

 mostly used as stock. Sometimes spelled Gleditschia. 



Gleichenia. Gleicheniacece. 



Increased by division of the plant. See Ferns, page 312. 



Globularia. Globulariacece. 



Propagated by division and by seed. 



Gloriosa. Liliaceoe. 



Offsets are commonly employed for propagation when they are 

 produced (about the old bulb) ; seeds are readily used, started in 

 bottom heat. The bulb-like tubers may be cut in two for purposes 

 of propagation. 



Gloxinia (Sinningia speciosa). Gesneriacece. 



Gloxinia seeds should be sown the latter part of winter, in well- 

 drained pots or small pans of finely sifted soil, of peat, leaf -mold 

 and sand in about equal proportions. The seeds should be covered 

 slightly, then carefully watered, and placed in a temperature of 

 about 70. If seeds are sown in spring, blooming tubers should 

 be had the following winter. 



Cuttings of the shoots may be taken after the old tubers start 

 in spring, and placed in a propaga ting-frame. Leaf-cuttings, 

 with a small portion of the petiole attached, give excellent re- 

 sults, especially when the leaves are firm and nearly matured. 

 Leaf-cuttings are made after the manner of Fig. 110; a little 

 tuber forms on the end of the leaf -stalk, and this is removed 

 and handled like any small tuber; or the last leaf may be laid 

 flat, as for begonia, and the ribs cut at intervals. Also grafted 

 on tubers, much as for dahlia and peony. See Gesneriaceoe. 



Glycosmis. RutaceoB. 



Cuttings may be used, started under glass ; seeds, when obtain- 

 able. 



Glycyrrhiza (Liquorice). Leguminosoe. 



Propagated by division and by seeds ; roots left in the ground 

 after harvesting may produce a succeeding crop.
