 Sansevieria zeylanica. 



(1) LEAF CUTTINGS (Fig. 56). There are 

 few plants which can be grown from leaves ; 

 among these are the Sansevieria zeylanica and 

 begonia. Fleshy leaves most readily respond 

 to this manner of propagation. The leaves may 

 be placed upon moist sand and pegged down at 

 the main veins, or the base of the leaf buried in 

 the sand. Roots are thrown out at the c^U ends 

 of the veins, and new plants are formed at 

 these points (Figs. 56, 57, 58). 



(2) STEM CUTTINGS. Directions for propagating by 

 means of stem cuttings : (a) Cut thrifty shoots from 

 different species of plants as, geranium, coleus, agera- 

 tum, heliotrope, verbena, tomato, nasturtium, etc.
