cordate at base, crimson-maroon, with or without a feathered, 
whitish, central band, or dotted with white on a light or 
dark green ground. Arakan Hills, Birma, 1890, There are 
three forms of this : guttulata (slightly striped), picta (painted), 
and punctata (dotted). 
Hybrids. Some of the best-known are ALFRED MAME, DUCHESS 
DE BRABANT, FRANCOIS MARCHAND, H. WALTER, LApDy 
BuRTON, MADAME ALESCH, MADAME VAN LANGENHOE, MADAME 
WALLERS, Mrs. H. WALTER, SILVER QUEEN, and SOUVENIR 
DE MADAME VAN HOUTTE. 
SOPHORA. To the species and varieties described 
on pp. 459-60, Vol. III., the following should be added: 
S. japonica hybrida (hybrid). ‘This differs from the typical 
:* weeping *” Sophora in the strong, horizontally-spreading main 
branches, and in the long, thin, pendulous smaller ones. 1893. 
S. platycarpa (flat-fruited). This is scarcely distinguishable 
from S. japonica in habit and general aspect, but differs 
markedly in having flatter pods. Japan, 1896, 
SOPHRO-CATTLEYA. These are bigeneric hybrids 
derived from the intercrossing of the genera Sophronitis 
and Cattleya.

SOPHRONITIS. Syn. Sophronia. To the species 
and varieties described on p. 460, Vol. III., the following 
should be added: 
S. grandifiora aurantiaca (orange). A variety with dark 
orange-red flowers. 1886. (R. H. 1886, p. 492.) The type is 
shown at Fig. 679. 
Ss Rossiteriana (Rossiter’s). jl. yellow, large and full. 
S. militaris is, according to the ‘‘ Index Kewensis,” a form of 
S. grandijlora. . 
S. pterocarpa is now regarded as synonymous with S. cernua. 
SORI. The plural of Sorus (which see). 
SOUR. Land that is wet or badly-drained is Sonr, 
and unfitted to grow cultivated plants or trees upon. 
Borders planted with Vines or other fruit trees under 
| glass quickly become sour if the drainage is not good ; 
i and the same applies to any plants in pots. Soil for 
| potting, or for making fruit-borders, should always be got 
from sound land, and not from wet ground ; from the latter 
it would be Sour and poor in quality and plant-food. 
SOUTH AFRICAN YELLOW-WOOD. See 
Podocarpus elongata. 
SOUTHWELLIA. Included under Sterculia (which 
see). 
SOWING. The Sowing of seeds requires careful 
judgment and knowledge, not only as to the where and 
how, but also as to the proper season. For instance, 
many seeds will germinate at once if sown immediately 
after they are ripe, but if kept for some time, they 
will remain dormant for many months. Many of the 
Primulas are cases in point. Other seeds, such as Melons, 
Marrows, Brassica, &c., will germinate freely after keeping 
for some years. In Sowing seeds in the open ground, 
the soil ought to be fine and friable, dry, and parting 
freely from the rake or feet. When the soil is damp, 
and adheres to the tools and feet, it is almost impossible 
to sow the seeds properly; and if a little dry or hot 
weather follows, the ground bakes and hardens, and 
germination is almost impossible. 
The quantity of seed to sow of any kind must be 
determined upon by the knowledge of the sower, as, for 
instance, Peas and Beans should be sown very thinly, 
while Radishes and all Brassica may be sown much more 
thickly ; bat with all outdoor Sowings, care should be 
exercised that the seeds are not sown too deeply. Fine 
seeds, like those of most Hardy Annnals, ought to be merely 
covered with the finest film of fine soil, otherwise many will 
fail to get through the soil ; larger seeds, such as those of 
the Turnip in vegetables, and Sweet Williams (Dianthus
