Lamiaceae & Verbenaceae Week: VERBENACEAE Trees UD 7 10 2011 TECTONA 2nd species
ushadi Micromini
Dear all:
Submitting Tree
Species: * Tectona hamiltoniana *
Family: Verbenaceae
Photographed in July 2007
Site: Kolkata Botanical Garden, Shibpur
Tree ID: Identified and labeled by Bot Garden Botanists
UD note:
Both of these trees are planted in Bengal and rest of the NE India
as garden and Avenue trees in Urban landscapes..
This Tectona has a distinctly different Bark habit than the T.
Grandis tree….
T. Hamiltoniana bark is brownish grey and peels of in roundish patches
revealing a pale grey patch, which
darkens as it ages…
it also flowers earlier (April and May) than
T. Grandis ( July and August) ,
and T. Hamiltoniana leaves are only a 7-8 inches long..
T. Grandis is used for red and yellow dyes (leaves) and
Wood for medicinal purposes for heachache
and inflammatory conditions,
besides being used for railway treks and furniture making…
Much has been written about Tectona Grandis…
and large plantations exist in India, Burma, Indonesia and around the world…
Not much writings about about T. Hamiltoniana,
although its wood is described
as being heavier, better shine taker when used in cabinetry,
Yet neglected , as far back as 1978 it was
reported as
part of list of “Species Undergoing
Genetic Impoverishment” …
Dont know if things have changed!!!

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...

trees books as possible
