refers the appearance to "a fusion of two flowers,
accompanied by suppression and modification."[445] As, however,
no details are given in support of this opinion, it may be
conjectured that the two additional stamens were members of the
inner whorl _a_ 1, _a_ 2, and thus the conformation would be
the same as in the flowers just mentioned. The figures given by
Mr. Moggridge bear out this latter view, while they lend no
support to the hypothesis advanced by him. Nevertheless, no
decided opinion can be pronounced by those who have not had the
opportunity of examining the flowers in question.

Alphonse de Candolle[446] figures a flower of _Maxillaria_ in
exactly the same condition, so far as the stamens are
concerned, as in the Ophrys flowers just mentioned. It is
curious to observe that in many of these cases the two lateral
petals are suppressed.

Von Martius mentions the occurrence of three anthers
(_naturaliter conformatae_) in _Orchis morio_.[447] Richard,
as cited by Moquin-Tandon, Lindley, and others, describes and
figures a peloria of _Orchis latifolia_ with regular triandrous
flowers.[448]

The writer has examined, in the Royal Gardens at Kew, a flower
of _Cattleya crispa_ in which were three stamens, the central
one normal; the two lateral ones, belonging probably to the
inner whorl, were in appearance like the lateral petals, and
one of them was adherent to the central perfect column.
Duchartre[449] mentions a flower of _Cattleya Forbesii_ in
which there were two labella in addition to the ordinary one,
the column being in its normal condition. From the analogy of
other cases it would appear as if the additional labella in
this instance were the representatives of two stamens of the
outer whorl. Beer likewise has put on record the existence of a
triandrous _Cattleya_.[450]

A specimen of _Catasetum eburneum_ forwarded by Mr. Wilson
Saunders was normal so far as the sepals and two lateral petals
were concerned, but the anterior petal or labellum was flat and
in form quite like the two lateral ones; the column was normal
and in the situation of the two anterior stamens of the outer
series A 2, A 3, were two labella of the usual form (fig. 156,
p. 291). Perhaps the _Oncidium_ represented at p. 68, fig. 29,
may also b
