trailing rock plants, possessing a very 
neat and varied appearance, the foliage 
of many being particularly beautiful; 
they delight in sandy soil and an elevated 
position. A few of the smaller kinds 
require the protection of a frame through 
the winter, and should therefore be grown 
in pots. 
SCABIGSA (Rasmee.) Nat. Order 
Dipsaceee. The annual species are pretty, 
hardy ornaments to the flower-garden, 
and merely require to be sown in March 
where they are designed to bloom; the' 
herbaceous species grow freely in any 
moderately good soil. 
SCJBYOLA (Linn.) Nat. Order 
Sceevolaceee. Eree-flowering ornamental 
plants, with blossoms of various shades 
of white, blue, red, or violet; the New 
Holland species require the ordinary 
treatment of greenhouse plants, and 
those from the East and West Indies 
should be placed in the stove. They 
delight in a mixture of peat, loam, and 
sand, in about equal quantities. 
SCHIZANTHUS (Ruiz and Pavon.) 
Nat. Ord. Scrophulanacece. Very hand¬ 
some, tender annuals, universally grown 
for decorating the greenhouse in sum¬ 
mer. S. pinnatus and porrigens need 
only be sown in spring, on a gentle heat, 
and afterwards nursed in a moderate 
hotbed; but the finer kinds, such as S. 
Hooked or retusus , are much better when 
sown in August, and kept in small pots 
in the greenhouse through the winter; 
they should then be placed in large pots 
in March or April, and will form fine 
plants, loaded with flowers through the 
following summer. 
SCHIZOPETALON (Sims.) < Nat. 
Ord. Cruciferee. The only species of 
this genus (S. Walkeni ) is a curious 
little half-hardy annual, with pure white 
flowers, singularly notched or cut at the 
edges of the petals, whence its name. 
It should be raised in a gentle heat in 
March, and in May be transferred to a 
warm situation in the borders of the 
flower garden. 
SCHOMBURGKIA (Bindley.) N. 
Ord. Orchidacece. A very handsome 
genus of epiphytes, with large pseudo¬ 
bulbs and strong leathery leaves; the 
flower spikes are produced from the 
apex of the pseudo-bulbs, and are from 
three to four feet in length, bearing large 
rich-coloured flowers of singular form. 
The plants should be attached to a piece 
of wood, and suspended from the roof of 
the stove; they require a high, moist at¬ 
mosphere in the growing season, and a 
very dry one when at rest. S. tibicinus 
is perhaps the finest. 
SCILLA (Linn.) N. Ord. Liliacea. 
Very pretty bulbous-rooted plants, nearly 
all of them hardy, and very desirable, on 
account of their early habit of flowering. 
They should be planted in November, in 
light rich soil, either in the open ground 
or in pots. S. amoena , blue; bifolia , 
red, blue, or white; brevifolia, pink; and 
sibenca , blue, are among the most beau¬ 
tiful and earliest, as they produce flowers 
from January to April. 
SOU TTELLARIA (Linn.) Nat. Ord. 
[abiatce . The hardy species are pretty 
plants for the front of the beds in the 
flower garden; their flowers are for the 
most part blue, and very showy; they 
grow freely in any common soil, and are 
little trouble. The greenhouse kinds 
are scarcely worth culture, among the 
many other truly beautiful objects more 
deserving the space they would thus 
occupy. 
SCYPHANTHUS (Sweet.) N. Ord. 
Loasacece. S. elegans is a very pretty 
half-hardy climbing annual, with lively 
yellow flowers ; it should be raised in 
autumn or early spring, and brought 
forward by repotting, allowing it plenty 
of air till May, when it may be placed 
out of doors. The leaves possess the 
power of stinging in an eminent degree. 
SEDUM (Linn.) Nat. Ord. Cras- 
sulacece. Eor rockwork no genus offers 
more suitable objects than this. All 
are hardy, and naturally adapted for 
covering places of the kind, most of them 
thriving even on the bare stone. There 
is a great diversity in the character of 
the numerous species, and subjects may 
be easily selected appropriate for any 
position. The flowers, which are freely 
produced, are in many instances very 
beautiful.
