Well, badthings@Flickr must be able to read my mind, because I've long wanted to have Ixia viridiflora on BPotD (original posted via the Flickr BPotD Group Pool). badthings also posts as MMW over on Two Gardens (today's image was part of this post). Thank you!
Green ixia, or Groenkalossie in Afrikaans, is a cormous perennial native to "lower slopes of mountains in the Tulbagh District of Western Cape" in South Africa. It had a slightly larger range in the late 19th / early 20th century, when it occurred in two other Districts, but it has since been extirpated from both of these areas. Like many South African flowers, Plantzafrica.com provides an excellent resource for learning more: Ixia viridiflora.
The pollination syndrome of Ixia is known as cantharophily, or, pollination by beetles. The article above points to monkey beetles (the tribe Hopliini in the scarab family) as the primary pollinators. For an example of a monkey beetle pollinating a flower (in this case, a Moraea (Iridaceae)), see Flower Pollination by photographer Colin Paterson-Jones.
More photographs of Ixia viridiflora are available from the Pacific Bulb Society Wiki. An illiustration of the plant, from the Missouri Botanical Garden Rare Books Collection, is available here: Ixia viridflora.
Photography resource link: Long-time BPotD readers may remember this entry on The Art of Christian Staebler. I was thinking about Christian a couple weeks ago and wondering what he was working on these days -- and a couple weeks later (out of the blue), he sent me an answer. scannography, the art of scanning, is a collaborative website run by Christian that highlights the work of scannographers from around the world.
