amurensis, 6', wh. 

 Maackia amureiisis). 



CLADANTHUS. 



A plant (ord. Composite) related to Anthemis. 

 The only species is proliferus, a half-hardy annual, 

 2', July, yellow, but of no garden value. Common 

 soil. 



CLADRASTRIS. 



Pretty, hardy, deciduous trees (ord. Legu- 

 minosa'), with spikes of white flowers in July or 

 August. They like a sunny situation and a warm, 

 dry soil. Propagated by layers or by budding or 

 grafting ; also by imported seeds. 

 Principal Species : 



tiuctoria, 15', Jy., wh. 

 (KI/HX. lutea and Virgilia 

 lutea) . Yellow Wood. 



CLARKIA. 



Charming hardy annuals (nrd. Onagrariem), with 

 bright-coloured flowers and of slender branching 

 habit. The leading species, elegans and pulchella, 

 differ mainly in the former having entire petals 

 and the latter being lobed. They are both of 

 great beauty in the bolder or in flower beds. 

 Propagated by seeds sown in the open where they 

 are to bloom in March or April, or in autumn for 

 spring bloom, in the reserve garden, whence they 

 may be removed in spring, with soil attached, to 

 where they are to flower. Protect the latter in 

 hard frost with branches or Aster stems. Thin 

 out the seedlings to 'J" apart. Kiel), well-manured 

 garden soil.

CLAY. 



Clay enters to some degree into the composition 

 of all fertile soils. When it is found in excess the 

 soil is called a clay soil ; and as it is wet, sour, and 

 unworkable in winter, and in hot, dry summers 

 develops yawning cracks or fissures on its surface, 

 it is not wholly desirable. It must, however, be 

 remembered that clay suits some crops admirably, 

 notably Celery. It may be greatly improved and 

 rendered fertile by burning on a good body of fire 

 in the garden ; also by ridging and trenching. 

 Clay is useful for adding to soils that are too 

 light and for puddling the sides and bottoms of 

 ponds. 



CLAYTONIA. 



Dwarf, rather succulent, hardy annual or 

 tuberous-rooted plants (ord. Portulacese), which 

 like a rather shady position in leaf soil and loam 

 or peat. The annuals are propagated by seeds 

 sown in spring; the others by offsets and division 

 in spring.

CLARY. 



The old English Clary, or Sage (Salvia 

 Sclarea), is a native plant which is still grown 

 as a pot-herb and used in various ways. It 

 formerly had a great medicinal reputation, and 

 derived its name of Clary, or clear-eye, from the 

 seeds having been found useful to " clear the eye." 

 Raised from seeds sown in spring, and thinned to 

 2' apart. Light soil. 



CLAUSEN A. 



A small genus of stove evergreen trees (ord. 

 Rutacerc), that produce white flowers, and, in the 

 case of cory m biflora, edible fruits. A compost of 

 peat and loam answers well; propagation may 

 be effected from cuttings of ripe wood under a 

 glass in heat. 



Principal Species : 



corymbiflora, 15', Jy., wh. Wampii, !">', sum., wh. 

 peu'taphylla, 20', Jy., wli. The Wampee tree. 



CLAVIJA. 



These are evergreen trees (ord. Myrsineai) that 

 must be grown in the stove. Cuttings inserted in 

 sand under a bell-glass in heat root freely. Soil, 

 loam and peat in equal parts, with coarse sand. 



Principal Species : 



Claiulesti/M (sec Latlircca). 





SILVER oil PLATA UKAXOE (sec ^j. aio). 



CLEISOSTOMA. 



The genus Cleisostoma (onl. Orchidacese) holds 

 quite an unimportant position horticultural!/. 

 The several species are of comparatively small 



growth, and have .small and unattractive flowers. 

 Aerial roots are produced very freely, consequently 

 baskets or rafts, with a little peat and sphagnum,
