Fig. 2, Two concrescent flowers of Habenaria grandiflora Lindl.

The most noticeable feature of the double structure is the presence of two complete, normal columns, placed side by side, and separated by a two-nerved sepal, apparently a reduced lateral sepal belonging to the flower on the right. Both dor- sal sepals are present, the one to the right being 7-nerved, the other 5-nerved, The two outer lateral sepals are both 3-nerved, and well developed. The two outer petals are nearly normal, 2-nerved. There is no trace of the inner pair of petals. There is only one lip and spur, whether a double structure or not cannot be made out. The opening to the spur is unusually wide. The ovary (Eig, 3) consists of four car- pels, one pair of which is better developed than the other.
