Which plant has more species, Zigadenus or Fallopia?
Fallopia 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.
Taxodium Taxodium is a genus of one to three species (depending on taxonomic opinion) of extremely flood-tolerant conifers in the cypress family, Cupressaceae. The generic name is derived from the Latin word "taxus", meaning "yew", and the Greek word "εἶδος" ("eidos"), meaning "similar to." Within the family, "Taxodium" is most closely related to Chinese swamp cypress ("Glyptostrobus pensilis") and sugi ("Cryptomeria japonica").
