Rare plants in Forty Acre Rock Preserve

My husband and I both like to hike a lot. Many Saturday mornings are spent hiking in various state parks and forests close to our home.

Last Saturday’s hike was in a place called Forty Acre Rock, a National Natural Landmark in the Piedmont region of South Carolina. The forty Acre Rock is a huge granite rock and reaching it involves hiking through thick woods, past a small waterfall and a cave. The big rock has indentations on its surface, which collect water in late winter and early spring. The pools thus formed are a haven for some rare specialized plant species, many of which are endangered.

Some pictures of the rare plant species:

Diamorpha Smallii (Elf Orpine) a succulent plant from the family crassulaceae






The green plant with the tiny white flowers is called Amphianthus pusillus, which is listed as a threatened plant.
Found only in Alabama, Georgia and South Carolina, they are also called Snorklewort, Pool Sprite and Little Amphianthus.
It has a small life cycle, usually around a month.

These pools dry up in summer and the seeds spring up again the following year when water collects in the depressions.

Shilpa, these are fantastic pictures!

Thanks Manisha!
I wish I had taken better pictures though. My equipment cannot get good close up shots of tiny things.
The pics suddenly disappeared, I had to re-post the post!

Shilpa, look for the macro function - usually denoted by the flower symbol. Do you have that on your camera?

I'm torn between buying a Canon Rebel and a Nikon D70. I want to buy it soon!

Shilpa said...

Yes, yes buy it soon and show off the pictures on your photo blog.

I did use the Macro function on my point and shoot. I will have to wait a bit for my new better camera!

Hey Neighbour! I travel to Atlanta often to visit friends. I want to go to the ruby falls sometime.
