variegated leaves. Y. gloriosa recurvifolia is usually 

 dwarfer in the stem than the type, more inclined to branch 

 than the other species, and less rigid, with recurving 

 leaves that are not so sharp-pointed. The flower panicle 

 is large and very much branched. 



The Yuccas all do well if planted in light loam of good 

 quality. 



Zauschneria (Onagrarieae). 



Zauschneria californica. — Californian Fuchsia, or 

 Humming Birds' Trumpet. California and Mexico, 1847. 

 A small-growing, densely-branched shrub, with linear-

 scarlet tubular flowers, with a long, slender style re-

 and October. It is a pretty and distinct Alpine shrub, 

 and not being perfectly hardy should be assigned a rather 

 warm and sheltered position. 



Zelfcova (Ulmaceae). 



Zelkova acuminata (syns Z. japonica, Z. kaki, and 

 Planera acuminata). — Japan, about 1872. This resembles

 country. 



Z. crenata (syns Planera crenata and P. Richardi). — 

 Zelkova Tree. Western Asia to Mount Caucasus, 1760. 

 This is a handsome, large-growing tree, with oblong, 

 deeply-crenated leaves and small and inconspicuous 

 greenish, scented flowers. For avenue planting or as a 

 standard specimen this is a valuable tree, being quite 

 hardy, and of free and quick growth. Z. crenata pendula 

 is a good weeping form, and worthy of culture. 



Z. ceetica. — Crete. A pretty small-growing bush or 

 tree, about 20 feet in height, with crenate, leathery,
