Winter Break

Between Christmas travel and winter months, it may some months till you see anything new here. Untill then, I will work to clean up the place and add detail to those posts that lack information.

Ghost Plant: Monotropa Uniflora

(Mike discovered this oddity on a recent hike. If you discover any AR botanical oddities that you would like to post to this site, please let me know.)

Monotropa uniflora, also known as the Ghost Plant, Indian Pipe, or Corpse Plant is a herbaceous perennial plant, formerly classified in the family Monotropaceae, but now included within the Ericaceae. It is native to temperate regions of Asia, North America and northern South America, but with large gaps between areas.[1] It is generally scarce or rare in occurrence.
Unlike most plants, it is white and does not contain chlorophyll. Instead of generating energy from sunlight, it is parasitic, more specifically a myco-heterotroph. Its hosts are certain fungi that are mycorrhizal with trees, meaning it ultimately gets its energy from photosynthetic trees. Since it is not dependent on sunlight to grow, it can grow in very dark environments as in the understory of dense forest. The complex relationship that allows this plant to grow also makes propagation difficult. http://en.wikipedia.org/wiki/Monotropa_uniflora

This month's fungus is not a fungus at all, but is often brought in to forays and by students thinking it must be a fungus because it's white and doesn't have any chlorophyll. But it's really a flowering plant-- in the blueberry family! This is one of about 3000 species of non-photosynthetic (i.e. heterotrophic) flowering plants. http://botit.botany.wisc.edu/toms_fungi/oct2002.html

Umbrella Magnolia

Image by Allison Finn.

I will be adding information later, but his image of a flower I have never seen, comes to us from the Upper Buffalo Wilderness Area near Ponca AR, courtesy of Allison Finn. The interior "cone" of the Umbrella Magnolia appears to have common characteristics with the very present Southern Magnolia, but a much thinner and more symmetrical petal outcrop.
