Dendrocalamus Strictus, also called the Calcutta Bamboo or the Male Bamboo is one of the few species ( or probably the only one), which is almost solid (not hollow), unlike most other bamboos, which have a hollow internode. This characteristic of Dendrocalamus Strictus makes it rather special material of choice for walking sticks (bamboo canes), also called the "lathi" in the local vernacular. The bamboo cane is much stronger than rattan-cane and has a longer shelf life. This species of bamboo also works wonderfully well for manufacture of implement handles, baseball bats, Billy Clubs and other handcrafted impact weapons.

 Classification

Bamboo belongs to the "GRASS" family of plants-Poaceae. The anatomy of the bamboo plant is a complex system, comprising of two sets of structured vegetative axes: one above ground (the areal part) and the other below the ground (rhizome). The primary areal axis consists of jointed, tall, cylindrical stems, called culms, with branches, extending outward from the culms, developing laterally, constituting secondary aboveground axis. The rhizomes make up the underground axis (roots and buds).

The areal part or the stem is the item of commerce, when harvested on maturity.  it is usually straight and cylinder-like, and has nodes (diaphragms) and internodes, which are normally hollow. 
Each node has two closely positioned rings, the lower one called sheath ring, and the upper, the stem ring. The sheath ring is a scar left behind after the sheath leaf falls off. The stem ring is a scar formed after the inter-nodal growth ceases. The part between the rings is the node itself.
Bamboo internodes are usually hollow inside, barring some rare species, e.g. Dendrocalamus Strictus. Depending on the bamboo species, wall thickness of the stem can vary greatly from thin walled to totally solid.

Bamboo resource in India
India is the second richest, next only to China, in terms of bamboo genetic resources, both collectively, accounting for more than half of the global bamboo resources. More than 136 species of bamboos are said to be occurring in India, out of which, 58 species of bamboo belonging to 10 genera are distributed in the northeastern states. The annual production of bamboo in India is around 4.6 million tonnes.

Bamboo in the Global Context
An evergreen, of the family Poaceae (GRASSES), bamboo is the one of the fastest growing woody perennial on the planet. Most bamboo species/genotypes grow in the tropics; however, some varieties occur naturally in subtropical and temperate zones of all continents except Europe.
