Pineapple

The pineapple (Ananas comosus) is a tropical plant and fruit (multiple), probably native to Brazil or Paraguay. It is a tall (1–1.5 m) herbaceous perennial plant with 30 or more trough-shaped and pointed leaves 30–100 cm long, surrounding a thick stem. The leaves of the Smooth Cayenne cultivar mostly lack spines except at the leaf tip, but the Spanish and Queen cultivars have large spines along the leaf margins. Pineapples are the only bromeliad fruit in widespread cultivation.
The name
The name pineapple in English (or piña in Spanish) comes from the similarity of the fruit to a pine cone.
The word "pineapple", first recorded in 1398, was originally used to describe the reproductive organs of conifer trees (now termed pine cones). When European explorers discovered this tropical fruit, they called them "pineapples" (term first recorded in that sense in 1664) because it resembled what we know as pine cones. The term "pine cone" was first recorded in 1695 to replace the original meaning of "pineapple".
[1]
In the scientific binomial Ananas comosus, ananas, the original name of the fruit, comes from the Tupi (Rio de Janeiro, Brazil) word for pineapple nanas, as recorded by André Thevenet in 1555 and comosus means "tufted" and refers to the stem of the fruit. Other members of the Ananas genus are often called pineapple as well by laymen.
