384 ANDR@CIUM OF 
conformate) in Orchis morio.! Richard, as cited by Moquin-Tandon, 
Lindley, and others, describes and figures a peloria of Orchis latifolia 
with regular triandrous flowers.” 
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? 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 1t 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.* 
A specimen of Catasetwin 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 Oncidiwm represented at p. 68, 
fig. 29, may also be explained on the supposition that the two lateral 
lobes of the labellum in this flower were the representatives of stamens. 
In Fig. 193 is shown the arrangement of parts in a flower of Ophrys 
aranifera. Here there were three sepals, two lateral petals, one of 
which was adherent to the side of the column; the central labellum was 
seemingly deficient, but there were two pseudo-labella placed laterally 
in the position of the two antero-lateral stamens of the outer series 
(A2, A3). Within these was another perfect stamen occupying the 
position of the anterior stamen of the inner series (43). In another 
flower of the same species, gathered at the same time (fig. 194), there were 
three sepals not at all different from those of the normal flower. The 
three petals next in succession were also, in form and position, in their 
ordinary state. In colour, however, the two upper lateral petals differed 
from what is customary, in having the same purplish-brown tint which 
characterises the lip. Within these petals, at the upper part of the 
flower, there was the ordinary column, and at the opposite side, alter- 
nating with the petals before mentioned, two additional lip-like petals, 
one provided with a half-anther containing a single perfectly formed 
pollen-mass (A2, A3). It is, perhaps, worthy of notice that the ar-
