rally of the darkest shades of green, may be 

 planted singly for contrast, or in masses to 

 give an effect of shade. They are all very 

 hardy, but with the exception of Taxus 

 baccata,) the common yew, they do not 

 attain much size. T. Canadensis is of a 

 pale colour ; T, b. variegala and T, b. 

 foliis-variegatis have a fine golden tinge. 



Yuc'ca (nat. ord. Lilia'ceae). 



Yuccas are popularly known as Adam's 

 Needle. They are perfectly hardy plants, 

 of quaint appearance, forming striking 

 objects in garden scenery. Yucca gloriosa 

 recurvifolia has graceful drooping leaves, 

 and forms a most desirable plant for vases, 

 or for planting as a specimen on lawns or 

 in the parterre. Yuccas grow best in a 

 dry but rich sandy loam, and will succeed 

 well if planted on rock-work, to which they 

 impart quite a tropical aspect. They are 

 propagated by division of the root, or by 



pieces o f the root placed in sandy soil in 

 heat. K filamentosa, or Silk Grass, and 

 Y.f.flaccida are desirable varieties. The 

 flowers arj white, tinged with green. 



Zausehne'ria (nat. ord. Onagra'rieae). 

 A very handsome Californian perennial 

 plant, in bloom from June to October, with 

 a profusion of beautiful tube-shaped flowers. 

 It succeeds best in dry gravelly soil, and is 

 most easily propagated by division of the 

 roots or by seeds, sown in heat in spring. 



Ze'a (nat. ord. Gramin'ese). 



This is the Indian corn, a very ornamen- 

 tal annual plant. It should be raised in a 

 hotbed early in spring and planted out in 

 May or June. There are numerous varie- 

 ties, but Zea Mayo, or Maize, is the best 

 known. It seldom brings its fruit to per- 

 fection in this country. It is the " Mealies" 

 of Southern Africa. 



Zie'ria (nat. ord. Ruta'cese). 



A remarkably pretty greenhouse ever- 

 green shrub. It succeeds best in a mixture

 by cuttings placed in sand and struck in 

 heat. There are not many species, and it
