h will breed, not only among
themselves, but also with the Brazilian Loelias, decline an alliance
with their Mexican kindred. But Baron Schroeder possesses a hybrid of
such typical parentage as _Catt. citrina_, Mexican, and _Catt.
intermedia_, Brazilian. It was raised by Miss Harris, of Lamberhurst,
Kent, one single plant only; and it has flowered several times. Messrs.
Sander have crossed _Catt. guttata Leopoldii_, Brazil, with _Catt.
Dowiana_, Costa Rica, giving _Catt. Chamberliana_; _Loelia crispa_,
Brazil, with the same, giving _Loelio-Cattleya Pallas_; _Catt.
citrina_, Mexico, with _Catt. intermedia_, Brazil, giving _Catt. citrina
intermedia_ (Lamberhurst hybrid); _Loelia flava_, Brazil, with _Catt.
Skinneri_, Costa Rica, giving _Loelio-Catt. Marriottiana_; _Loelia
pumila_, Brazil, with _Catt. Dowiana_, Costa Rica, giving
_Loelio-Catt. Normanii_; _Loelia Digbyana_, Central America, with
_Catt. Mossiae_, Venezuela, giving _Loelio-Catt. Digbyana-Mossiae_;
_Catt. Mossiae_, Venezuela, with _Loelia cinnabarina_, Brazil, giving
_Loelio-Catt. Phoebe_. Not yet flowered and unnamed, raised in the
Nursery, are _Catt. citrina_, Mexico, with _Loelia purpurata_, Brazil;
_Catt. Harrisoniae_, Brazil, with _Catt. citrina_, Mexico; _Loelia
anceps_, Mexico, with _Epidendrum ciliare_, U.S. Colombia. In other
genera there are several hybrids of Mexican and South American
parentage; as _L. anceps_ x _Epid. ciliare_, _Sophronitis grandiflora_ x
_Epid. radicans_, _Epid. xanthinum_ x _Epid. radicans_.

But among Cypripediums, the easiest and safest of all orchids to
hybridize, East Indian and American species are unfruitful. Messrs.
Veitch obtained such a cross, as they had every reason to believe, in
one instance. For sixteen years the plants grew and grew until it was
thought they would prove the rule by declining to flower. I wrote to
Messrs. Veitch to obtain the latest news. They inform me that one has
bloomed at last. It shows no trace of the American strain, and they have
satisfied themselves that there was an error in the operation or the
record. Again, the capsules secured from very many by-generic crosses
have proved, time after time, to contain not a single seed. In other
cases the seed was excellent to all appearance, but it has resolutely
refused to germinate. And further, certain by-generic seedlings have
utterly ignored one parent. _Zygopetalum Mackayi_ has been crossed by
Mr. Veitch, Mr. Cookson, and others doubtless, with
