Palm tree seen in Lalbagh on 8/11/14.
Short tree, almost like a bush.
yes almost has no trunk in its mostly short-lived lives
grown commercially in indonesia for its :snake fruit" and edible fruit
its the salacca zelacca... what a weird name (not sure of the spelling, pl check it)
almost sounded to me like a rock star's name when I first heard it
Did you see any fruits at the base? 
The correct name is........Salacca zalacca.
... had suggested the same to me.
He was there when these pictures were taken.
He had specially come to show me the trees I hadn't found in Lalbagh.
Very kind of him.
No, we did not see any fruits at the base.
Eager to taste them.
Have you tried?
And when I had some time on hand, these are the pictures I have taken, unlike my California posts.... where I was just running.
no i did not eat it
i don't eat unwashed stuff
no use getting delhi belly in touristy hotels but locals said they eat it..
thanks for the correct spelling...
and yes I know you can take good pictures that's why i keep asking you to
If this is Salacca zalacca, where did you take this photograph? The leaves are rather strange to me.  I want to share my pictures of the snake fruit.  A certain cultivar may have >1 m trunk.

Thanks for your pictures showing the fruits.
My pictures, as mentioned were taken in Lalbagh Botanical Gardens, Bangalore, India.
palm tree with bamboo like leaves
yours are the same terminal ones seem to be together and older ones have separated (it does that in fish tail palm too)
Loved to see your pictures of the fruits
typical fruits with scaly skin
is there a factor of maturity of the palm before it fruits or does it have to have lots of them around like the date palms? please share...
... can tell you where...
but she mentions Lal bagh
a botanical garden of extensive well tended collection from all over the world...
... has been showing us the trees and plants there... do search our database for his name...

I am not sure this is a Salacca – it looks more like Daemonorops jenkinsiana
