38-4 ANDRCECIUM OF 



ccynformaioi) in Orchis morio.^ Richard, as cited by Moquiu-Tandon. 

 Lindley, and otliers, 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 stataens, 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 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* 



A specimen of Catasetum ehumeum 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 fonn (fig. 156, p. 291). Perhaps the Oncidium 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 Ophi-ys 

 aranifera. Here there were thi*ee 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 

 (A 2, A 3). Within these was another perfect stamen occupying the 

 position of the anterior stamen of the inner series (a 3). In another 

 flower of the same species, gathered at the same time (fig. 191), 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 pui'plish-brown tint which 

 characterises the lip. Within these petals, at the upper part of the 

 flower, there was the ordinai-y 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 

 poUen-mass (a 2, A 3). Tt is. perhaps, worthy of notice that the ar-
