Wattianum_ from _O.
Harryanum_ and _O. hystrix_. And it must be observed that we cannot
trace pedigree beyond the parents as yet, saving a very, very few cases.
But unions have been contracting during cycles of time; doubtless, from
the laws of things the orchid is latest born of Nature's children in the
world of flora, but mighty venerable by this time, nevertheless. We can
identify the mixed offspring of _O. crispum Alexandrae_ paired with _O.
gloriosum_, with _O. luteopurpureum_, with _O. Lindleyanum_; these
parents dwell side by side, and they could not fail to mingle. We can
already trace with assurance a few double crosses, as _O. lanceans_, the
result of an alliance between _O. crispum Alexandrae_ and _O.
Ruckerianum_, which latter is a hybrid of the former with _O.
gloriosum_. When we observe _O. Roezlii_ upon the bank of the River
Cauca and _O. vexillarium_ on the higher ground, whilst _O. vexillarium
superbum_ lives between, we may confidently attribute its peculiarity of
a broad dark blotch upon the lip to the influence of _O. Roezlii_. So,
taking station at Manaos upon the Amazons, we find, to eastward,
_Cattleya superba_, to westward _C. Eldorado_, and in the midst _C.
Brymeriana_, which, it is safe to assume, represents the union of the
two; for that matter, the theory will very soon be tested, for M.
Alfred Bleu has "made the cross" of _C.
