Bamboo

The bamboos are a subfamily (Bambusoideae) of flowering perennial evergreen plants in the grass family Poaceae. Giant bamboos are the largest members of the grass family. In bamboo, the internodal regions of the stem are usually hollow and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement. Bamboos include some of the fastest-growing plants in the world.The word bamboo comes from the Kannada term bambu, which was introduced to English through Indonesian and Malay.
