All-Red Snow Plants – Nourished by Fungi
IT emerges from the soil like a mini-plastic Christmas tree in the image of a red Mexican succulent. But it’s not a succulent or even an entire plant and it’s not from Mexico. Rather it’s the flowering stalk of a species closely related to the cranberry, blueberry, azalea and rhododendron and it grows in the Sierra Nevada of California. Apparently called snow plants because they emerge as the snow melts, these stalks were photographed in June along the Sliver Fork Trail in the Sierra Nevada by Aom, a hiking buddy of Larry – a regular commentator at this blog.
The species, Sarcodes sanguinea, has no chlorophyll and so, like most plants, can’t obtain its energy directly from the sun. Instead it is parasitic on fungi that also colonise the roots of pine trees. Experiments with radioactive carbon 14 show that the sugars from the conifer roots enter the fungi and then are transferred into the roots of the snow plant.
So we have a true vascular plants with flowers and seed-bearing capsules, that can’t photosynthesis, instead getting its energy from pine trees via fungi.
Does this all have something to do with being perfectly red?
Oil Washes Ashore
Up to 100,000 litres of oil leaked into Moreton Bay after the Pacific Adventurer cargo ship was holed on Wednesday morning, and the slicks are now blanketing 60 kilometres of Queensland’s coastline. Read more here.
New Jungles
By one estimate, for every acre of rain forest cut down each year, more than 50 acres of new forest are growing in the tropics on land that was once farmed, logged or ravaged by natural disaster.

Do Plants Produce Methane?
The recent finding that plants could be a major source of the atmosphere’s methane is challenged by new research. Read more here.
