While Michelia is of the genus of flowering plants, what is Houttuynia?
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".
Lauraceae Lauraceae are the laurel family, that includes the true laurel and its closest relatives. This family of flowering plants comprises about 2850 known species in about 45 genera worldwide (Christenhusz & Byng 2016 ). They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as "Sassafras", are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. "Cassytha" is a genus unique to the Lauraceae family in that it is a genus of parasitic vines.
