Drosera filiformis!
Just as Bob announced his discovery, Brian Barnes arrived on the scene. We all converged upon the wet seepage that Bob had found.
Yep, sure enough--Drosera filiformis growing in the silica sand, only
having recently emerged from dormancy.
The plants were clearly smaller than Drosera tracyi.
They looked to my eyes very much like Drosera filiformis
from the New Jersey area,
which can be very red, and not at all like plants from the Carolinas,
which seem to be paler. But...I must point out that my observations of this plant
over its Atlantic coast range are somewhat episodic and are certainly not comprehensive.
