psules, and sowed them, obtaining several hundred fine
plants. Pods are often imported on _Cyp. insigne_ full of good seed.
In the circumstances enumerated we have the explanation of an
extraordinary fact. Hybrids or natural species of Cypripediums
artificially raised are stronger than their parents, and they produce
finer flowers. The reason is that they get abundance of food in
captivity, and all things are made comfortable for them; whilst Nature,
anxious to be rid of a form of plant no longer approved, starves and
neglects them.
The same argument enables us to understand why Cypripeds lend themselves
so readily to the hybridizer. Darwin taught us to expect that species
which can rarely hope to secure a chance of reproduction will learn to
make the process as easy and as sure as the conditions would admit--that
none of those scarce opportunities may be lost. And so it proves.
Orchidaceans are apt to declare that "everybody" is hybridizing
Cypripeds nowadays. At least, so many persons have taken up this
agreeable and interesting pursuit that science has lost count of the
less striking results. Briefly, the first hybrid Cypripedium was raised
by Dominy, in 1869, and named after Mr. Harris, who, as has been said,
suggested the operation to him. Seden produced the next in 1874--_Cyp.
Sedeni_ from _Cyp. Schlimii x Cyp. longiflorum_; curious as the single
instance yet noted in which seedlings turn out identical, whichever
parent furnish the pollen-masses. In every other case they vary when the
functions of the parents are exchanged.
For a long time after 1853, when serious work begun, Messrs. Veitch had
a monopoly of the business. It is but forty years, therefore, since
experiments commenced, in which time hundreds of hybrids have been
added to our list of flowers; but--this is my point--Nature has been
busy at the same task for unknown ages, and who can measure the fruits
of her industry? I do not offer the remark as an argument; our
observations are too few as yet. It may well be urged that if Nature had
been thus active, the "natural hybrids" which can be recognized would be
much more numerous than they are. I have pointed out that many of the
largest genera show very few; many none at all. But is it impossible
that the explanation appears to fail only because we cannot yet push it
far enough? When the hybridizer causes by force a fruitful union betwixt
two genera, he seems to triumph over a botanical law. But supp
