Polygonatum

Polygonatum , also known as '''King Solomon's-seal, Solomon's seal, or sealwort', is a genus of flowering plants. In the APG III classification system, it is placed in the family Asparagaceae, subfamily Convallarioideae (formerly the family Ruscaceae). It has also been classified in the former family Convallariaceae and, like many lilioid monocots, was formerly classified in the lily family, Liliaceae. The genus is distributed throughout the temperate Northern Hemisphere. Most of the approximately 63 species occur in Asia, with 20 endemic to China.

==Etymology== Polygonatum'' comes from the ancient Greek for "many knees", referring to the multiple jointed rhizome. One explanation for the derivation of the common name "Solomon's seal" is that the roots bear depressions which resemble royal seals. Another is that the cut roots resemble Hebrew characters.
