The cleistogamic flower is quite small, rather flattened 
and zygomorphic, especially in its older state. It is raised 
on a short peduncle, and is set obliquely against the main 
axis. Just below the calyx are two small lateral tooth-like 
bracts and one large central one. The calyx is relatively of 
large size, is synsepalous and shows five tooth-like lobes 
along its upper margin. Above is set the small cap-like 
asymmetric corolla, fitting down within the lobes of the 
calyx. On its inner surface arise four small stamens, two 
being larger than the others. A well-developed ovary fills 
most of the flower cavity. Posteriorly arises a single style. 
It curves forward under the corolla cap, and bends down so 
that its stigma lies between the four anteriorly set stamens. 
Around the anterior base of the ovary a considerable nectary 
is developed. This probably represents the fifth stamen. 
In the chasmogamic flower, the calyx and ovary are 
almost exactly similar to those above. The unlikeness lies 
in the structures of the distal region of the flower. The
