Lagerstroemia microcarpa Wight

Scientific Naming and Growth Height

Lagerstroemia microcarpa Wight is a tree that grows taller than 30 meters (100 feet).

Bark Characteristics

It can be easily recognized by its smooth white bark, which peels off in large, papery flakes.

Natural Habitat

This species grows naturally in moist deciduous and semi-evergreen forests of the Western Ghats, and is typically found in forest openings.

Light Requirement and Flower Trait

It is a light-demanding tree in the later stages of its life cycle, and produces beautiful white flowers.

Mature Tree and Seedling Presence

Although large, mature specimens of Lagerstroemia microcarpa are abundant in natural forests, seedlings are usually absent.

Annual Seed Production

According to research from KFRI, the tree produces millions of seeds every year, but very few to none of these seeds germinate.

Seed Viability Issue

This low germination rate occurs because most seeds are non-viable, as they lack a functional embryo (viable embryos only occur rarely).

Germination Barrier from Seasonal Gap

The gap between seed dispersal and the rainy season also contributes to poor germination.

Fire Impact on Regeneration

KFRI research also found that forest fires negatively impact the species' natural regeneration rate.

Assisted Germination Efficacy

Assisted germination methods using vermiculite or foam sheet have been found to produce fairly reasonable germination percentages.

Future Conservation Need

Additional trials of these assisted methods may be needed in the future to prevent this species from disappearing from its native forests.
