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!!!

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...

I just discovered that (upon careful reading) ,
( prompted by Gurucharanji's write up in one of the threads)

that Tectona group/genus is now in Family: Lamiaceae

so an changing my database and annointating as many of my botany/
trees books as possible

Thanks for the education, Gurucharanji...
