Metasequoia was known only from fossils over 150 million years old until living specimens were confirmed in China in 1946. Only about 4,000 trees remained at the time, and every metasequoia in the world today descends from them.
The word 'ketchup' comes from '膎汁' (kôe-chiap) in the Chinese Min Nan dialect, meaning 'fish sauce.' It was originally a fermented fish and shellfish sauce—tomato ketchup was not invented until 1812.
Bamboo is not a tree but a grass — a cousin of rice. Depending on species, it flowers only once every few decades to 120 years, then dies. Since all stems in a bamboo grove grow from a single root system, when one flowers, the entire grove dies together.
