| The flowers of Zamioculcas are morphologically hermaphroditical, but physiologically unisexual. |
| In one study of 68 newly domesticated yams, just under a quarter were biochemically and morphologically very similar to existing varieties. |
| Each gametangium yields two morphologically isogamous nonflagellated gametes with anisogamous behavior. |
| The species is morphologically variable and exhibits more molecular variation than A. hypogaea. |
| It is strongly suspected that these three morphologically separate forms are different species. |
| These species are widely distributed in Upper Miocene and Pliocene deposits in tropical America, forming a morphologically distinctive group. |
