Sulphur 



STRYPHNODENDRON. 



Small stove trees (ord. Leguminosae), allied to 

 Adenanthera, and seldom cultivated. Propagation, 

 by seeds when obtainable, and by cuttings of half- 

 ripened wood in sand, under a bell-glass, in bottom 

 heat. Soil, loam, peat, and sand. Guianense (gym. 

 Acacia, Mimosa, and Piptadenia guianensis), 80' to 

 40', November, white, is the only introduction. 



STUARTIA. 



A small genus of hardy but much neglected 

 shrubs (ord. Ternstroeiniacese), with large and 

 handsome white flowers resembling single Camellias. 

 Propagation, by seeds, and by layers in autumn. Soil, 

 moist sandy loam ; if at all dry a liberal admix- 

 ture of peat must be given. On soil of the green 

 sand formation, where moisture is ample at all 

 seasons, they succeed well. 



Principal Species : 



pentagyna, 6' to 10', sum., grandiflora and jap- 



cream (syns. ovata and onica). 



Malachodeudron ovat- virgmica, 5' to 8', Ap.,

pseudo-camellia, 6' to 12', lachodendrouandmary- 



sum., creauiy wh. (xyns. landica). 



STYLIDIUM. 



Greenhouse herbs, rarely shrubs (ord. Stylidiese), 

 with narrow leaves and small flowers remarkable 

 for their sensitive styles. Propagation, by seeds ; 

 the herbs also by division, and the shrubs by cut- 

 tings under a bell-glass, in sand. Soil, mellow, 

 fibrous loam, with peat, leaf mould, and sand.

STYLOCORYNA. 



Stove evergreen shrubs (ord. Rubiacefe), few of 

 which are cultivated. Propagation, by cuttings in 

 sand, in a close case. Soil, equal parts loam and 

 peat, with sand. Coriacea, 4', stove, white, is in 

 cultivation, and should be treated like Gardenias. 

 Corymbosa is now Olostyla corymbosa. 



STYLOPHORUM. 



Hardy herbaceous perennials (ord. Papaveracese), 

 useful in the border. Propagation, by seeds, and 

 division of the roots in spring. Well-drained 

 garden soil. 



Principal Species : 



diphyllum, 9", Je., yel. diphylla, and M. petiol- 



(st/ns, ohioense, petio- ata).

STYPANDRA. 



Greenhouse plants (ord. Liliaceaa), allied to 

 Dianella. Propagation, by division in spring. 

 Soil, fibrous peat and loam, with coarse sand.

 or yel. 



STYPHELIA. 



Greenhouse evergreens (ord. Epacndese). Prop- 

 agation, by cuttings in sandy peat, beneath a bell- 

 glass, over gentle heat. Soil, fibrous peat, a little 

 loam, and some coarse sand. 

 Principal Species :- 



tubiflora, ">', Jy., sc. 

 viridis, 3i', My., gnu 

 (syn. viridiftora). 



STYRAX. 



Deciduous, hardy, or warm greenhouse shrubs (ord. 

 Styracess), some of great beauty when in flower. 

 Many of the species are of economic value, the 

 benzoin resin coming from the species of that name, 

 while storax, a balsamic resin, is derived from 

 officinale. Propagation, by cuttings, by layers either 

 in spring or autumn, and by imported seeds sown 

 as soon as received in a warm greenhouse. Soil, 

 light loam, with leaf mould, for the hardy species ; 

 a mixture of fibrous loam, peat, and coarse sand 

 for the tender ones.

SUCCULENTS. 



Under this general head may be grouped all 

 those plants possessing thick fleshy leaves and stems. 

 Succulents have comparatively few roots, hence 

 they do not become gorged with moisture during a 

 rainy season. On the other hand, they also have 

 thick skins on the leaves and steins, and few 

 stomata; hence even in the hottest and driest 

 times they give off little moisture. The majority of 

 Cacti are succulents, and among these the most 

 familiar genera are Cereus, Echinocactus, Epiphyl- 

 lum, Mammillaria, Melocactus, Opnntia, and Phyl- 

 locactus. In the natural order Liliacea? there are 

 numerous succulents, notably in the genera Aloe, 

 Gasteria, and Haworthia, while among Amaryllids 

 the extensive genus Agave is remarkable for its 

 succulent species. Some other orders are also well 

 represented among succulents, the best known 

 genera being Cotyledon, Crassula, Sedum, and 

 Sempervivnm (Crassulacese) and Mosembryan- 

 themum (Ficoidese). 



SULPHUR. 



As one of the ten essential elements which go to 

 build up the plant, sulphur plays a highly im- 

 portant part in the vegetable world. It is always 

 found in protoplasm, although its exact uses are 

 not defined. Probably the name sulphur suggests 

 to the gardener more vividly than anything else a 

 very useful and handy fungicide. Flowers of 



Styplmolobium (see Soplwra).

Stiflerokia (nee Hclimiopsis). 



Si/kana (sec Celosia).
