ITS ORCHID WEEK BABY, LETS CELEBRATE SPRING!

I did these a while back, it's time to revisit them! ORCHID WEEK STARTS ALL ORCHIDS NO STOPPING.

The first three are the ones I'm not very proud of - they are:

Tall Greenhood Pterostylis melagramma

Nodding Greenhood, Pterostylis nutans

Maroonhood orchid, Pterostylis pedunculata

Orchids are associated with huge flowers and exotic colours - but in Australia, we like them to be tiny weird little guys. We like 'em to look like bugs, spiders, ducks, and teeny hairy explosions.

#2355 - Pterostylis montana - New Zealand Mountain Greenhood

AKA Pterostylis furcata var. linearis.

An orchid endemic to the North, South, and Chatham Islands, and despite the specific is found in a wide range of habitats from dense forest to peat bogs.

The 300-odd species of Greenhood orchid are also found in Australia, New Caledonia, Papua New Guinea, and one Indonesian island. The first species described from New Zealand was the Tutukiwi in 1832, by Allan Cunningham. He named it Pterostylis macrophylla but did not publish his manuscript. Later it was recognised as the same as one collected by Joseph Banks on the Endeavour. With Cunningham's consent, the plant was named Pterostylis banksii in honour of Banks.

Greenhood Orchids

Last week walking Ralphie up in the bush, I stumbled upon a small group of endemic Pterostylis – Greenhood Orchids beside a fire-trail under a tree. I only had my phone and took a few shots. I returned the next morning armed with the OM1 and a few prime lenses. Laowa 7.5mm f2.0 – 1/20 sec; f/16.0; ISO 200 The first two shots give an overview of the forest where they are situated, on an exposed…

Australian orchid. Pterostylis genus.

[mybeingthere]

Pterostylis curta, the blunt greenhood, is a terrestrial orchid mainly from Australia. This terrestrial orchid emerges from a dormant corm to produce a single, quite strange, green and windowed flower. The flower uses visual or olfactory trickery (like many orchids) to attract certain flies.

It possesses a sensitive labellum which when triggered will pin the insect against the column of the flower for around a minute before releasing it. If all goes well, the insect will bear sticky pollinia away from the flower ensuring cross pollination when it visits another.

Like many geophytes (plants with underground storage vessels), it can also multiply asexually and establish genetically identical communities.

#2613 - Pterostylis oliveri - Oliver's Greenhood

Actually a fair-sized orchid - that isn't a Nasturtium in the background of the first photo.

Growing widely on the north end of South Island, in forest and scrub, often on the side of streams or in dense leaf litter from near Nelson to Arthurs Pass National Park but most often on limestone or marble. They can be abundant on marble.

First formally described by Scottish botanist Donald Petrie in 1894, and named atfer Professor Daniel Oliver of Kew Gardens.

Arthur's Pass, Aotearoa New Zealand.

I think this is Pterostylis grandiflora. I didn't know they could flower this early (literature says May to Aug). You can see the mature plants have narrow leaves, while the young ones are rosettes with heart-shaped leaves.
