face is absent. Probably these appendages are the lateral stigmas 
(see diagram‘). These two cases are to be compared with C. 
jlaccida as described by Masters, in which the two stamens 
nearest to the labellum, have developed into labella.

Flower tetramerous, ovary with 8, closer in pairs, grooves. 
At first sight the sepals are normal and three in number, they 
also occupy the same position relatively to one another, the 
two lateral S, and S, however with their bases a little more 
apart than ordinarily. On closer examination there appears 
between S, and §, a fourth sepal not quite as broad as the 
two. Between S, and S, there is a petal, an other between 5, 
and S;, both of them being normal. Besides ss 
there are two (normal) labella. Column a little Peet Bn

Hight flowers of the same raceme show the reversion of the 
stamens a’ and a**) and this in such a way that in six of the 
cases both can be distinguished with perfect certainty, whereas 
in the other two flowers this is certain only for one of them. 
The extra-stamens are less perfect than the ordinary anther, 
for as the latter bears two pollinia in each of its cavities, a’ 
1) This diagram has been taken from Masters (Veg. Terat.) and is referred to in 
indicating the position of the different parts of the flower whether or not normally 
having developed. 
2) In using the letters a', a? and so on we also refer to the diagram of Masters.
