Acaena is a genus of about 100 species of mainly evergreen, creeping herbaceous perennial plants and subshrubs in the family Rosaceae, native mainly to the Southern Hemisphere, notably New Zealand, Australia and South America, but with a few species extending into the Northern Hemisphere, north to Hawaii ("A. exigua") and California ("A. pinnatifida").
Aneilema is a genus of monocotyledonous plants of approximately 60 species.
 The vast majority of the species are native to sub-Saharan Africa, but a few are found in Oceania and one, "Aneilema brasiliense", is from South America.
 It is the third largest genus in the family Commelinaceae after "Commelina" and "Tradescantia", and it is one of only six genera in the family to occur in both the Eastern Hemisphere and the Western Hemisphere.
Nertera is a genus of about 15 species of flowering plants in the family Rubiaceae, native to the Southern Hemisphere, in South America and Australasia, with one species extending into the Northern Hemisphere in Central America, eastern Asia, and Hawaii.
 The name derives from the Greek word "nerteros", meaning low down.
 Common names include pincushion, coral bead or bead plant.
 They are prostrate, creeping, mat-forming herbaceous perennial plants growing to 20 - across or more but no more than a few centimetres high.
 The leaves are usually quite small, and when crushed may in some species release a foul smell (methanethiol) like the related woody genus "Coprosma".
 The flowers are insignificant and probably wind-pollinated.
 The fruit is usually a bright orange berry, but in some species may be a dry capsule.
Amanita muscaria, commonly known as the fly agaric or fly amanita, is a mushroom and psychoactive basidiomycete fungus, one of many in the genus "Amanita".
 Native throughout the temperate and boreal regions of the Northern Hemisphere, "Amanita muscaria" has been unintentionally introduced to many countries in the Southern Hemisphere, generally as a symbiont with pine and birch plantations, and is now a true cosmopolitan species.
 It associates with various deciduous and coniferous trees.
Adenophora is a genus of flowering plants in the family Campanulaceae, the bellflowers.

 It is native to the northwestern United States where it can be found in Oregon, northeastern California, and northwestern Nevada.
 It grows in mountain and plateau habitat.
 This is an annual herb producing decumbent, creeping, spreading, or upright branched stems up to 40 centimeters long.
 The leaves are oblong in shape and deeply lobed, measuring up to 3 centimeters long.
 The inflorescence is a one-sided cyme of many bell-shaped flowers each under a centimeter long.
 Unlike many phacelias, which bloom in shades of blue and purple, this species has yellow to golden flowers.
 It occasionally has purple edges on the corolla.
 The fruit is a fuzzy, oblong capsule a few millimeters in length containing up to 14 seeds.
