Facing away

Diplodium sp.- Shell Orchid

In this post, I will be dealing with Diplodium robustum, Diplodium sp. Adelaide Hills, and the hybrid the occurs from both.  These plants flower between May and August.

The plants of this species will either have a small rosette of leaves or a flower with leaves growing from the stem.  These orchids tends to form large colonies, but only 10% will flower.  An interesting observation is that these flowers will grow facing the slope.  It could be that this is where the pollinator will come from.  The reason is not known, but it does make it hard to photograph the front of the flower.

All the flowers are facing in one direction.
Note the little rosettes around the plants

Another example of the flowers all facing the banking

The two parent species of Diplodium are determined by the length of the spike on the end of the dorsal sepal.  D. robustum has long spike and is pictured below, left.  D. sp. Adelaide Hills has a short spike and is pictured below, right.  The hybrids are more likely to finish flowering before their parent plants.
