"Bambusa basihirsutoides" has 6 anthers growing to 7 mm in length and 2 to 3 stigmas. It is perennial and appears tufted with an underground stem. The lowest part of the stem is erect which allows it to grow up to a height of 700–1200 cm long. This is enabled by a woody stem without nodal roots that grow to 60–90 millimeters in diameter.
