Giby: Tectona hamiltonian is a native of Burma... Used to be planted in Calcutta as specimen (as in Kol Bot G, where I took the picture in 2007) and sometimes on streets. In the 40's its was listed as being present in the grounds of the zoo and near maidan... need to track them... donot know if they have survived... the years, pollution, rain, human greed etc..
I discovered on the net that it likes calcareous sandstone, as found in dry central parts of Burma... may be that's why it never overlaps with regions where Tectona grandis grows. May be that's why it never seems to have taken off in Calcutta where even Hooker seems to have planted a few... it does produce seeds but they do not seem to find a toehold in the rich fertile,, often soggy soil...
