The thread-leaf sundews of the Eastern North America are spectacular plants with erect, tall, filiform leaves. Backlit in the morning or evening light, their leaves burst with sunlight. There are two thread-leaf sundews (also known as dew-threads), known as either infraspecific taxa within Drosera filiformis, or as Drosera filiformis and Drosera tracyi. In this paper, I review their history of discovery, the details of their ranges, and the arguments regarding whether the two taxa should be treated as one species or two. I also describe the morphological differences between the two sundews. In total, this paper summarizes the current knowledge for this group, and also serves as a progress report on my continuing work on these plants.
