Dendrocalamus giganteus, known as giant
bamboo, is the tallest among the bamboos,
measuring on an average about 25 m high and 25
cm diameter. It is cultivated in Cox’s Bazar,
Banderban, Chittagong, Mymensingh, Panchagar,
Jessore and some other Districts ofBangladesh. Its
local names are wara bans, bhudumbans, bombai
bans, raja bans, kanchan bans, etc. It grows
luxuriantly in all the flood free areas.
It was reported earlier that D. giganteus
flowered at Calcutta Botanical Garden, India in
1860-61 and again in 1888 and in Burma in 1892
(Gamble 1896). Lahiri (1974) reported that one
clump introduced during 1880-88 at Kurseong
Division, India flowered in 1974. Bahadur (1979)
reported flowering of this species at Forest

Research Institute campus, Dehra Dun in 1979. As
reported by Gupta (1982), one clump flowered in
1981 along the Tuli-Wokha road of Nagaland,
India.
The exact flowering cycles (from seed to
seed) ofbamboos are known for few species. Most
of the pastreports on bamboo flowering cycles are
based on speculation and estimation (Hasan 1973,
Banik 1991). The flowering cycles for many
species of bamboo from India, Bangladesh and
Myanmar were reported (Cavendish 1905,
Blatter 1930, Bor 1941, Hasan 1973, Bahadur 1980,
Naithani 1990, Banik 1991, Alam 1995). This paper
presentsthe estima ted flowering cycles ofBambusa
burmanica Gamble, B. cacharensis Majumdar and
B. jaintiana Majumdar based on past records and
recent flowering (Table 1)
