Schomburgkia. Orchidaceoe. 



Propagated by parting or dividing the stems. See Orchids, 

 page 372. 



Sciadopitys (Umbrella Pine). Pinaceoe. 



Propagated by seeds and layers. Cuttings of the half-ripened 

 shoots, taken in summer and inserted in sand, in heat, root readily. 

 Seeds, if obtainable, give best results. 



Scilla (Squill). Liliacece. 



Slowly increased by seeds, but usually by bulbels or offsets, 

 taken after the foliage has matured. See Liliaceoe, page 349. 



Scirpus. Cyperaceos. 



Increased by seeds, suckers and divisions. 

 Scolymus (Spanish Salsify). Composites. 



Raised from seed sown in spring where plants are to stand. 

 Scorzonera (Black Salsify). Composite?. 



Grown from seeds, sown where the plants are to stand. 

 Scutellaria (Skullcap). Labiates. 



The herbaceous species are increased by seeds and division, 

 and the shrubby kinds by cuttings of half-ripened shoots in spring. 

 Seaforthia elegans: Archontophosnix. 

 Sea-Kale (Crambe maritima). Cruciferoe. 



Raised from seeds (globular pods) sown without being shelled, 

 usually in a seed-bed. When the young plants have made three or 

 four leaves, they should be removed to permanent quarters. Seed- 

 lings should furnish crops in three years. Increased also by root- 

 cuttings, 4 or 5 inches long, taken from well-established plants. 

 These should give plants strong enough for cutting in two years. 

 Sechium (Chayote). Cucurbitacece. 



The entire fruit is planted in early spring ; it contains one large 

 seed. 

 Sedum (Orpine. Stonecrop). Crassulacece. 



Handled by seeds, by division of the tufts, by cuttings of stems 

 or leaves in spring. Pieces of the plant usually grow readily, as 

 cuttings. Some of the kinds produce offsets. 

 Selaginella. Selaginellaceoe. 



Propagated by spores, as for ferns (which see) and by short 

 cuttings, inserted in early spring, in pots or pans. The cuttings of
