How many leaves does it produce in its centuries-spanning lifetime?Two. Welwitschia is endemic to the Namib desert. The age of individual plants is difficult to assess, but many plants may be over 1000 (or even 2000) years old. Because Welwitschia only produces a single pair of foliage leaves, the plant was thought by some to be neotenic, consisting essentially of a "giant seedling." However, research showed that its anatomy is not consistent with the giant seedling idea. Instead, the plant is more accurately thought of as achieving its unusual morphology as a result of having "lost its head" (apical meristem) at an early stage.very hard 27% OneOne12%TwoTwo27%More than 100More than 10036%More than 1000More than 100023%Created by: Katarzyna Dąbrowska.
