Are Amherstia and Hyacinth native to the same locations?
Amherstia Amherstia nobilis (Burmese: သော်ကကြီး ] ; the Pride of Burma, in the Fabaceae family) is a tropical tree with large, showy flowers. It is the only member of the genus Amherstia. It is widely cultivated for ornament in the humid tropics, but is very rare in the wild and has only been collected from its native habitat a few times. It is native to Burma (Myanmar), hence the common name. The scientific name commemorates Lady Amherst, (as does Lady Amherst's pheasant) and also her daughter Sarah. Another common name, the Orchid Tree, is otherwise reserved for members of the genus "Bauhinia".
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".
