Black Bean Tree, Old Airport Road, Bangalore

Saw this tree in bloom on 16/3/13 in Lalbagh.

Thought it to be Saraca asoca and didn’t pay much attention since I’ve seen those a number of times before in Mumbai.
There were some green pods lying down below the tree, didn’t know which tree they belonged to.
While going through my pictures, thought this could be Castanospermum australe and the pods might belong to this tree.

Kindly validate.

Yes looks like Castanospermum ausrtale

Yes, looks like Castanospermum australe to me too. I had posted the pictures of the flowers some time back ( I don’t know how to give the link!). I haven’t seen the pods though.

Thanks for confirming the id.
Wish I had taken more pictures.
In Jijamata Udyan, the flowers are very high up, you can only photograph the ones fallen down.
Have posted a picture earlier.

Pl. check with images at Swietenia macrophylla

May be.

Castanospermum australe:
From Rani Bag Mumbai.
Huge tree. No flowers were visible on the tree ….may be they were very high
Pictures of flowers fallen on the lawn below.

– Yes  .., this is Castanospermum australe A. Cuhn. , Australian chestnut. A very rare tree. I had  uploaded the same last year in mid March.  Had managed to capture a few flowers in the thick and high canopy. Yes, it is difficult to see the flowers in the canopy due to the unusual canopy of  the tree and  trees surrounding it !

Castanospermum australe A.Cunn. & C.Fraser ex Hook. as the name suggests, the seeds of this plant should be similar to that of chestnut.

Saw this tree on the roadside in Bangalore. Can any of you please help in ID’ing this tree?

Castanospermum australe.
The genus Castanospermum belongs to the Fabaceae family and has only one species – Castanospermum australe, commonly referred to as the Black Bean or the Moreton Bay Chestnut.

Thanks for the ID, …! Surprised to find this exotic australian species planted on the roadside. Probably the builder/developer might have planted these 2 trees in front of their business center. Not seen anywhere else on that stretch apart from these 2.
