Saururaceae
Saururaceae is a plant family comprising four genera and seven species of herbaceous flowering plants native to eastern and southern Asia and North America. The family has been recognised by most taxonomists, and is sometimes known as the "lizard's-tail family". The APG IV system (2016; unchanged from the 2009 APG III system, the 2003 APG II system and the 1998 APG system) assigned it to the order Piperales in the clade magnoliids.

Piperales
Piperales is an order of flowering plants (4,170 recognized species). It necessarily includes the family Piperaceae but other taxa have been included or disincluded variously over time. Well-known plants which may be included in this order include black pepper, kava, the many Peperomias, pepper elder, lizard's tail, birthwort, and wild ginger. The two perianthless families Piperaceae and Saururaceae are mainly herbaceous plants possessing highly reduced flowers. Classification APG system In the APG IV system, of 2016, this order is placed in the clade magnoliids and is circumscribed as follows: *order Piperales *: family Aristolochiaceae (including Asaraceae, Hydnoraceae and Lactoridaceae) *: family Piperaceae *: family Saururaceae This is an expansion from the APG system, of 1998, which used the same placement (in the magnoliids) but used this circumscription: * order Piperales *: family Aristolochiaceae *: family Lactoridaceae *: family Piperaceae *: family Sau ...

Saururus Stoobensis
''Saururus'' is a genus of plants in the family Saururaceae containing two species. ''Saururus cernuus'' is native to North America, and '' Saururus chinensis'' is native to Asia.

Houttuynia
''Houttuynia'' is a genus of two species in the Saururaceae native to Southeast Asia. One species, '' H. cordata'', is widely cultivated as a culinary herb. The genus was originally described in 1783 by Carl Peter Thunberg when he formally described ''H. cordata'' as the only species. It remained a monotypic genus until 2001 when Zheng Yin Zhu and Shi Liang Zhang discovered and described a second species native to China, '' H. emeiensis'' but the validity still unestablished.Wu Wei, Zheng Youliang, Chen Li, Wei Yuming, Yan Zehong, and Yang Ruiwu. 2005PCR-RFLP analysis of cpDNA and mtDNA in the genus ''Houttuynia'' in some areas of China.''Hereditas'' 142: 24-32. It was named after Dutch naturalist Martinus Houttuyn Maarten Houttuyn or Houttuijn (1720 – 2 May 1798; Latinised as Martinus Houttuyn) was a Dutch naturalist.

Saururus Cernuus
''Saururus cernuus'' (lizard's tail, water-dragon, dragon's tail, swamp root) is a medicinal and ornamental plant native to eastern North America. It grows in wet areas or shallow water, and can be up to about a meter tall. The native range covers much of the eastern United States, as far west as eastern Texas and Kansas, south to Florida, and north to Michigan and New York state. ''Saururus cernuus'' also occurs in Ontario Canada. It is an obligate wetland plant and able to grow in saturated soils. ''Saururus cernuus'' is a herbaceous perennial that gets its most frequent common name, lizard's tail, from its white flowers that bloom in the summer months. The inflorescence is usually 6 to 8 in long. After floral maturity the white flowers turn brown, giving the plant its namesake, lizard's tail. The leaves are usually heart-shaped, arrow-shaped, or lance-shaped, and are arranged alternately on the stem. When the leaves are crushed they release a citrus or sassafras aroma. As an ...
