Sheepless – Pink Shepherds’ Crook Orchid

Geodorum terrestre - Pink Shepherds' Crook Orchid

Geodorum terrestre – Pink Shepherds’ Crook Orchid

Geodorum literally means earth gift and terrestre = terrestrial.

previously known as G. densiflorum

This very attractive ground orchid responds to the early rains of the wet season with rapid, active growth.

The plants grow with tightly packed fleshy pseudobulbs supporting yellowish green, heavily pleated leaves.

The soft pink flowers are presented on a arching stem that allows the flowers to hangs down, perhaps to help them avoid the impact of heavy rainfall on the fertile parts of the flower.

The plants are regarded as widespread and common.

They can be found in a variety of forest types and habitats but a good level of moisture and light are usually required for healthy growth.

Here at Wild Wings & Swampy Things they have gradually worked their way down from the remnant vegetation on the hillsides. They have persisted in patches of Guinea Grass – Panicum maximum but seem unable to penetrate the several different introduced species of Brachiaria sp.

Hence we have a strong desire to rid our property of these dominating exotic grasses and have greatly reduced their presence.

While the outside of the flower is a lovely soft pink, the labellum has a heavily veined deep red upper surface with a splash of bright yellow in the center.

The flowers are pollinated by our small stingless honey bees, although some forms are supposed to self pollinate.

I have chosen this last post for 2009 for Denis Wilson who has given me such enjoyment with his regular orchid posts.

Nose into “Common Snout Orchid”

Dienia montana was previously known as Malaxis latifolius.

The vernacular name of “Common Snout Orchid” is most unfortunate for this seemingly attractive terrestrial orchid. I cannot see the reason for this name?

They tend to grow in small colonies in shaded, damp areas with a good covering of leaf mulch as you can see in the first photo.

With the recent rains of the last four weeks several terrestrial orchids have started to burst forth. They don’t muck about either. This patch of about 20 plants have only had leaf material showing for about three weeks and already the lower flowers on the flower spikes have blooms that are fully open.

The flowers are crowded on a vertical spike ripening from the bottom towards the top.

The flowers are a mere 4-6 mm across, making it very difficult to enjoy the true shape and colour.

They are also a bit of a challenge to photograph as the plants seem to like living in low light situations.

We have quite large clumps of these orchids in gullies coming off the hillsides that have re-vegetated themselves over the last 20 years. Gradually, as the trees have advanced down the slope, so have several species of terrestrial orchid.

The flowers turn from a lime green to a purplish brown as they mature.

Unfortunately, like many terrestrial orchids the plants are very seasonal and dry off and shrivel towards the end of the wet season.

On another note some months ago I posted the flowering Sarcochilus minutiflos which also has a very small flower. Yesterday while mowing I came across a plant that had fallen out of its tree. The flowers had obviously been fertilised and the pods were fully developed. I was quite surprised by the size of the pods. They were about 6-7 cm long and about 4 mm wide. Quite a contrast to the flowers that produced them that were only 6-8 mm across.
