In this post, the orchids are uncommon because of an uncommon feature of ridgeforms. Below are two examples of what I believe to be the outer ranges of shapes of ridgeforms. Most types of ridgeforms tend to be elongated and narrow, but there are also uncommon ridgeforms that do not follow this pattern.

In example 1, the right labium is fused with a ridgeform that is elongated, but is very thin, almost like a flap that could cover the right labium in the closed position or natural state.

In example 2, the left labium has a ridgeform that is not elongated, but short, thick and bulbous.

Both examples illustrate the range of variation in ridgeforms.

Do you have images of an uncommon orchid feature? Send them to me at Contact and I will post them on this blog if they qualify as uncommon.
