Pineapple (Ananas comosus)
The leaves of the cultivar 'Smooth Cayenne' mostly lack spines except at the leaf tip, but the cultivars 'Spanish' and 'Queen' have large spines along the leaf margins. Pineapples are the only bromeliad berry/fruit in widespread cultivation. It is one of the most commercially important plants which carry out Crassulacean acid metabolism, or CAM photosynthesis.
