තල[Tala]/Talipot palm(Corypha umbraculifera)

Leaves of Talipot palm tree have been using for writing since ancient times and it has a very restricted distribution (1) and it is always associated with human habitations. So it is believed that it was introduced to the Sri Lanka from India for the purpose of documenting Buddhist sacred text and other writings. Flowering occurs when the tree is around 40 years old and most probably all the trees in the vicinity blooms with flowers simultaneously possibly because they are of same age due to seed crop of same parent tree. Other than for writing, leaves use for thatching, as umbrellas and for basket and mat weavings.               

(1) According to the Flora of Ceylon Vol 14 its distribution is limited to the narrow belt bordering northern wet and intermediate lowlands [Molagoda, Warakapola, Mirigama, Gampaha Mathale, Gampola, Galewela] and the eastern intermediate lowlands [Badulla, Ranwala, Godakawela]
