Teak tree is one of the most common Indian trees. People can usually find these nice and striking trees in separated clusters that grow best by the riversides. The scientists know teak trees as 'Tectona Grandis'. Both the names 'Tectona' and 'Teak' have been derived from the Portuguese name 'Teca'. The word came from the Greek word 'Tekton' that means 'a carpenter'; and in Latin, 'Grandis' means 'large'. This tree is a member of 'Verbenaceae' family. These trees can grow up to 45 metres in height when they are in their highest maturity of about sixty to eighty years. The trees have a lot of names in various languages like 'Takku' in Sinhalese; 'Kyun' in Burmese; 'Satgun' in Hindi and Bengali; 'Tek' or 'Teaku-maram' in Tamil and 'Jati' in Malayalam. The tree is more popularly known as 'Indian Oak'.
Indian teak tree grows naturally in dry and moist deciduous forests from the southern extension of the Aravalli mountain ranges
to southern Uttar Pradesh
, through Madhya Pradesh
and southwards through peninsular India. Its best growth occurs in the warmer and moister parts that receive around 125 to 250 cm of rainfall annually with a dry season of 3 to 5 months on fertile, well-drained soils.
From the month of June to September every teak tree looks very fresh with all the new leaves and also capped with a haze of blossom. This time, they form a marvelous spectacle. However, for almost the rest of the year, the teak tree does not look that beautiful, as a certain type of insects eat up nearly all the huge leaves making the tree somewhat bare and uncovered. However, this helps in studying the wonderful network of veins of the tree. Growing in pairs, the large and strong leaves of the tree remain diagonally to the next. The tender leaves can grow up to 60 cm in length. The branchlets of the tree bear countless, little white flowers. They also remain in pairs and alternate in direction. Each scented flower normally contains five or six-petals. Out of the million flowers that the tree produces, only a few appear to be fertile. In the month of September, those flowers also increase in size to 2.5 cm for the maximum. The teak tree looks very gorgeous at this time even though most of its leaves have been eaten up.
