Description

Wonderful, weird, strange, bizarre, fascinating, and unique, are the words that are used to describe Welwitschia mirabilis. It has only two opposite leaves produced from marginal grooves on the crown, each splitting into many parallel sections, twisting. The leaves continue to grow throughout the entire life of the plant. They are broad, strap-shaped and may reach a length of 13 feet (4 m) and over. The stem is unbranched, woody and up to 20 inches (50 cm) tall. Welwitschia mirabilis is a genus with separate male and female plants.
