Acacia (Wattle) for ID :: May MK002 : 13 posts by 4 authors. Attachments (10)
Please help me to confirm if this is Acacia melanoxylon?
Habitat: open scrub forest
Date: 27 April 2015
Place: Kancheepuram dist., (Chennai outskirts) TN Alt.: 14 m asl
It is perhaps Acacia holosericea, an introduced species in Tamil Nadu.
As per ILDIS, Acacia holosericea G. Don is an introduced species in Tamilnadu & West Bengal.
I am not aware of the current name but this phyllode-bearing Acacia species is unmistakable by the markedly flattened branchlets. Introduced by the Planters of Tamil Nadu. I have also seen it in Goa.
Pl check for Acacia longifolia. The fruits of Acacia holosericea /A. mangium are quite different : http://www.pioneercatchment.org.au/plants-database/acacia-holosericea- The fruits in your photograph is long and slightly curved. To unfold the ID of your Acacia the buds need to unfold !
Here the pods are flattened which rules out A. longifolia having terete pods.
Recently I had an interaction with Dr. Bruce Maslin, World Expert of Acacias. He is of the opinion that Acacia holosericea is currently an accepted name.
That specimen cannot be Acacia melanoxylon because the flowers are in axillary spikes (not heads in racemes) and the pods are wrong.

Hope that you are in receipt of the forwarded message from Dr. Bruce Maslin, relating to the identity of the present photographs. Hope that the matter is clarified now. However, as desired by Dr. Maslin, please attach high resolution images to enable him to see the leaf venation.
Thank you very much for the effort in sorting out the ID of this species. I will send the large original files of leaves to you in separate mails.
I tried to forward the message to Dr. Bruce but it is indeed bouncing back saying that the attachment is too heavy. Probably it exceeded the permissible limit. Anyway, we are now knowing the correct identity of this species. I am myself making the necessary corrections in the forthcoming publication of Flora of India.
Thanks for sending photographs of this new Acacia species. … s efforts to get the plant ID is laudable. This has helped us to find out the proper ID. Thanks to ….
It is my pleasure to share few images of Acacia colei (Fabaceae)
Habit: Small tree
Habitat: An escape in A.auriculiformis plantation
Sighting: Kadur, Chikmagalur, Karnataka, about 900 msl
Wonderful. The species in now aggressively spreading in Tamil Nadu and under cultivation in Goa. Not recorded for Karnataka State so far. Earlier confused with Acacia holosericea.
Thanks … The proliferation may be attributed to contamination of A. auriculiformis seeds in the first place and to the resilience of A.colei

Name: Acacia holosericea A.Cunn.
Date: 25 Feb 2016
Place: Tirupathi hills, AP
Alt.: 120 m asl
It has been planted by the forest department.
I send you Acacia mangium for comparison. Attachments (2)
Perhaps Acacia colei once again. Minor leaf venation needs to be enlarged and seen in absence of the fruits.
I am attaching herewith a publication which may be found helpful in determining the actual identity of the species introduced (from Australia), collected, identified and distributed (preserved) as Acacia holosericea in India.
