Pseudolarix is a monotypic genus of conifer in the family Pinaceae.
 The sole species, Pseudolarix amabilis, is commonly known as the golden larch, though it is not a true larch ("Larix"), being more closely related to "Keteleeria", "Abies" and "Cedrus".
 It is native to eastern China, occurring in small areas in the mountains of southern Anhui, Zhejiang, Fujian, Jiangxi, Hunan, Hubei and eastern Sichuan, at altitudes of 100 - .
 Golden larch is sometimes known under an old scientific name "Pseudolarix kaempferi", but this may cause confusion with "Larix kaempferi", the Japanese larch.
Epithelantha (button cactus) is a genus of cactus that is native to northeastern Mexico, and in an area from western Texas to Arizona.
 "Epithelantha" has two species, "Epithelantha micromeris" and "Epithelantha bokei".
 The name "Epithelantha" refers to the flower position near the apex of the tubercles.
