Related documents: [0]  [DOC] Fallopia is a genus of about 12–15 species of flowering plants in the buckwheat family, often included in a wider treatment of the related genus "Polygonum" in the past. The genus is native to temperate and subtropical regions of the Northern Hemisphere. The genus includes herbaceous perennial plants, herbaceous vines, and woody vines. [END] 
[1]  [DOC] Nicandra is a monotypic genus of flowering plants in the nightshade family containing the single species Nicandra physalodes. It is known by the common names apple-of-Peru and shoo-fly plant. It is thought originally to have been native to Peru (known elsewhere as an introduced species and sometimes as a weed) and is found nowadays as a ruderal species in tropical, subtropical and, to a lesser extent, temperate areas all over the world. It has also long been cultivated as an ornamental plant for its attractive flowers and curious fruits (the latter sometimes dried for use in floral design) and has been adopted into the traditional medicine of countries far-removed from its original home.
