WAHLENBERGIA ( Scheadee. ) 
Nat. Order Campanulaceee. Like the . 
whole of the order, these are very pretty 1 
plants; the perennial herbaceous species 
require to be potted for protection in 1 
the winter ; the annuals should be raised 
on heat in the spring, and planted out 
when danger from frost is past. 
WATSONIA (Kee.) Natural Order , 
Induces. Interesting and beautiful 
plants when in flower; their general 
habit and appearance resemble greatly 
the Gladiolus, though they are some¬ 
what more tender, requiring to be plant¬ 
ed in a frame filled with loam, leaf- 
mould, rotten dung, and sand, the roots 
should be taken up in autumn. 
WISTARIA (Nuttall.) Nat. Ord. 
Leguminosce. One species of these 
plants, W. sinensis , is, perhaps, the finest 
hardy climber we possess; its lovely 
pendant panicles of light blue flowers, 
produced in profusion when grown in a 
warm situation, are altogether without a 
rival; the plant succeeds in a border of 
rich loamy soil, and should have its 
branches nailed to a south wall; it is 
also sometimes planted in the borders of 
the greenhouse, and trained over the 
roof or walls, where it makes a fine 
appearance. In the autumn the ends of 
the unripened shoots should be cut _ off, 
and those which proceed in a foreright 
position spurred in; the other species, 
W. frutescens, is also an elegant plant of 
similar habit, though not quite so pro¬ 
ductive of flowers. The first is very 
commonly known as Glycine sinensis. 
WITSENIA (Linn.) Nat. Order 
Iridaceee. W. corymbosa is a pretty 
greenhouse plant extensively cultivated 
for its lively blue flowers. It should be 
grown in two parts sandy peat and the 
remainder loam, and have abundance of 
air at all tunes. 
WULEENIA (Jacquin.) Nat. Ord. 
Scrophulariaceee. W. carinthiaca is a 
very pretty herbaceous plant, effective in 
the border of the flower garden through 
the summer, on account of its bright blue 
flowers. It should be grown in very 
light and moderately rich soil; on the ap¬ 
proach of whiter it should be potted, and 
kept in a pit to guard it from severe frosts. 
XERANTHEMUM (Touenefoet.) 
Nat. Ord. Composites. Hardy annuals of 
the easiest culture, merely requiring to 
be sown where they are desired to 
bloom; then flowers, from their pecu¬ 
liar dry character, may be preserved a 
very long time after they are cut from 
the plants, and this circumstance has 
given rise to the English name Everlast¬ 
ing. 
YUCCA (Linn.) Nat. Ord. Liliaceee. 
The greater part of these plants are 
hardy enough to withstand our winters, 
and are generally planted as detached 
specimens on lawns ; their leaves resem¬ 
ble those of the aloe, though the thick 
succulent stem of the plants give them 
the' appearance more of a palm; the 
flowers are produced on an erect spike 
proceeding from the heart of the plant, 
and are very ornamental. The hardy 
kinds only require to have the leaves 
tied together in an upright position to 
guard the centre from excessive wet, 
and the other portion does very well in 
a greenhouse through the winter. Rich 
turfy loam and sand should be used to 
grow them in ; there are a considerable 
number of species, the blossoms of all of 
them are greenish white, and on esta¬ 
blished plants are produced annually. 
ZAMIA (Linn.) Nat. Ord. Cycadace.ee. 
These extraordinary plants are remark¬ 
able for their bony fronds or leaves, for 
the most part armed with very strong 
spines or sharp angles; the species Z. 
horrida has thorns several inches in 
length, and as hard as horn. All of them 
flourish in the stove, when potted in 
sandy loam, better than elsewhere, 
though a few may be preserved in the 
conservatory, where their progress is, 
however, not at all rapid. 
ZEPHYRANTHES ( Heebeet. ) 
. Nat. Ord. Amaryllidacene , Beautiful 
. bulbous-rooted plants, whose flowers are 
white or red, produced several together 
! on the top of an erect stem. Coming 
chiefly from South America they require 
■ the treatment recommended for Ama- 
[ i ryllis.
