 distant whorls, on scapes 1 to 2 ft. 

 high. 



The double-flowered variety, some- 

 times known as ja/x»u'c>i flore j^eno, 

 is a handsome plant with roundish 

 heads of white flowers. 



This species and its variety are 

 quite hardy, and may be grown on the 

 margins of lakes, streams, ponds, etc., 

 where they will be more or less 

 submerged. The double-flowered 

 variety can only be propagated by 

 division. The single-flowered kinds 

 in the same way, and also by seeds. 



S. sinensis (5. aiijantea ; S. lanci- 

 folia), from China, is a beautiful 

 plant about 3 to 5 ft. high, with lance- 

 shaped leaves and white flowers, 

 having the greenish outer segments 

 flushed %\-ith rose (Bof. Mag. t. 1631).

SALVIA {salvo, to save ; in allusion 

 to the medicinal virtues). Sage. 

 Xat. Ord. Labiateae. — A large genus 

 containing some 450 species, many 

 ornamental and easily grown. The 

 only tuberous-rooted species worthy 

 of note is — 



S. patens {S. $})ectahilis ; S. mac- 

 ■rant ha). — A beautiful hairy Mexican 

 perennial, about 2h ft. high, having 

 ovate-triangular leaves with roxinded 

 teeth and lobed at the base. The 

 deep blue flowers, over 2 ins. long, are 

 bome in whorls on erect spikes 

 during the summer and autumn 

 months. (Bot. Mag. t. 380S.) 



This species may be grown in the 

 open air during the summer months, 

 and in the milder parts of the 

 Kingdom may be left in the open 

 ground so long as the blackish 

 spindle-shaped roots are protected 

 from frost in the same way as 

 Dahlias. It may be increased from 

 seeds sown in gentle heat in spring ; 

 from cuttings in the same way as 



Dahlias : and also by division of the 

 root-stocks. 



SANDERSONIA (after J. Sander- 

 son, a secretary of the Natal Horti- 

 cultural Society). Xat. Ord. Liliaceae.

S. atirantiaca, a native of Xatal, 

 having a tuberous root-stock from

 stems 3 to 6 ft long, furnished %\-ith 

 alternate, stalkless, lance-shaped 

 leaves. The bell-shaped or inflated 

 flowers, with six shallow lobes, are 

 of a beautiful orange colour, droop- 

 ing from the axils of the leaves in 

 July and August. (Bot. Mag. t. 

 4716.) 



This pretty plant is best grown in 

 a warm greenhouse in a compost of 

 rich sandy loam with a little leaf- 

 soil or well-decayed manure, and 

 may be trained up piU:\rs, or on 

 trellises in the same way as the 

 Gloriosas or Littonias, to which it 

 is closely related. In autumn the 

 stems die down, after which the root- 

 stocks should be kept dry until the 

 following spring. In lie milder 

 parts of the Kingdom this plant 

 may be grown in the open aii-, the 

 roots being taken up and stored for 

 the winter.
