Botanical Description
Selaginella tamariscina is a resurrection spike-moss in the family Selaginellaceae, native to East and Southeast Asia where it grows in dense rosette-like cushions on dry rocks and cliff faces. The plant is a lycophyte (fern-ally), not a true moss, reaching 5β15 cm tall with a short woody caudex bearing tightly imbricate, scale-like microphylls arranged in four ranks along branched stems. During drought the fronds curl inward into a tight ball and turn brown, then unfurl and green again upon rewetting β hence the name βresurrection plant.β Reproduction is by heterosporous strobili borne at branch tips. In traditional Chinese medicine the whole dried plant (Juan Bai) is harvested year-round and used as a hemostatic and blood-invigorating herb.
