SEED SOWING
A number of the seeds of all seed capsules should be sown as soon as
they are ready, the remainder being carefully stored for sowing later if
required, the seeds sown and those retained being carefully marked with
the number in the record book.
The manner of sowing the seeds varies in different establishments,
satisfactory results having been obtained under very dissimilar
conditions. Failure at first is the usual record of the amateur taking
up Orchid hybridisation, although some few get fairly good success from
the commencement, while those who have had a run of bad luck usually
conquer in the end if they persevere. A scientific reason for some
failures has been given, namely, that an endophytic fungus said to be
necessary to the development of the freshly germinated seeds is wanting
in the early stages, but may be developed naturally after a time, and a
better state of growth result. Be that as it may, it is a curious fact
that the line of demarcation between failure and success in the matter
of raising seedling Orchids is very narrow, and, when the operator
succeeds in raising a fair proportion of the seeds sown, he is generally
surprised at his former want of success, apparently under practically
similar conditions. Formerly the common practice was to sow the seeds on
the surface of the material in which the parent plant was growing, or a
plant of some kindred variety. This practice has been generally
satisfactory and continues in most amateur collections to the present
day. A plant in a basket, or suspended pan or pot, is best, the subject
being chosen for the good quality of the peat, Osmunda fibre, or
whatever material the plant may be growing in. The Sphagnum-moss on the
surface should be clipped very short, the plant thoroughly watered with
rain water, and allowed to drain for a few hours. The seeds should be
sown a few at a time, on the point of a knife or thin strip of hard wood
or ivory, and carefully and evenly distributed over the surface of the
material in which the selected plant is growing. In all cases the number
of the record in the stock-book should be attached, a small celluloid
tablet fastened by a thin wire being the best label, as it is clean and
durable. Hybrids of Laelia, Cattleya, and other true epiphytes should be
suspended in a warm, intermediate house, and Cypripediums and
