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".
Hymenolobium Hymenolobium is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Faboideae. It was formerly assigned to the tribe Dalbergieae, but recent molecular phylogenetic evidence has placed it in a unique clade named the "Andira" clade.
