A reply from Mahadeswara ji:

"For me  the ID on the name board seems to be correct.  It is Bauhinia monandra.       Bauhinia krugii  is the synonym of Bauhinia monandra "

[Aarti S. Khale]

Resurfacing my post as the tree under discussion seems to be the same.

Kindly confirm id.

Mahadeswara ji has already confirmed the name plate to be correct.

... to me this flower looks very much like the Hong Kong orchid, Bauhinia blakeana.

Have not yet seen Bauhinia monandra - the name suggests Bauhinia bearing one stamen ... though not sure monandra in this context implies one fertile and some infertile.

... photos at:

Thanks Dinesh ji for the id and additional information.

I too think this should be Bauhinia blakeana.

So I suppose the name plate at Lalbagh is wrong.

There are some others too with wrong id, which need to be corrected in Lalbagh, Bangalore.

Aarti

Hi,
I agree the flower looks like B. x blakeana, but I have never seen leaves like those in the pictures on that species.  That pinkish tinge and the way the new leaves are folded is not seen in B x blakeana. That tree's new foliage is always a lightish green. Veins also look more prominent in your pics. IT is not easy to make a definite judgement based only on these images.

best regards
Radha

[Aarti S. Khale]

Radha ji,

Thanks for your feedback.

Hoping to find the correct id soon.

Regards,

Aarti

[Gurcharan Singh]

I think there should be little difficulty in getting correct identity if Aarti ji remembers major aspects of the plant. Leaves are very small in B. krugii

Bauhinia monandra (syn: B. krugii)              Bauhinia x blakeana

1. Leaves 2.5-4 cm long.                            1.  Leaves 9-13 cm long

2. Flowers in a short raceme.                     2. Flowers in a large panicle

3. Fertile stamen 1.                                   3. Fertile stamens 5, 3 longer.

4. Pod formed.                                          4. No pod formed

5. Flowers pink with purple veins.               5. Flowers with purplish petals.

6. Petals barely 3 cm long.                        6. Petals 5-8 cm long.

Thanks Gurcharan ji for the summary.

The ones in Lalbagh have lots of pods.

Atleast I know two of them one near the rose garden, another near the palms

I have the pictures of both of the trees in this link. I have also uploaded in the group

[Aarti S. Khale]

Gurcharan ji,

Thanks a lot for the distinguishing features between the two.

Both the set of pictures posted by Raman ji are of the same tree photographed by me.

This is near the palms, a small tree with two main trunks.

Leaves are definitely not small, but large.

Flowers very dark with purple petals.

Only confusing factor is the pods. Although I haven't seen any, Raman ji's photographs have pod formation.

You can see the pinkish tinge on the new leaves.

Even Ranjini ji has posted the same flower earlier.

Although the flowering season was over when I took the pictures, the single dark flower caught my attention. Had not come across a Bauhinia so dark pink, almost purple.

Regards,

Aarti

[Gurcharan Singh]

Aarti ji

If the tree really bears mature pods, it can't be B. x blakeana, which being a hybrid does not set seeds/pods,

   One has to check the number of fertile stamens and leaf size to confirm.

I don't think it is B.monandra as B. monandra clearly has only one big single visible stamen. Others may be small or rudimentary. Here I can see many and all appear equal in size.

[Gurcharan Singh]

I too think the tree label is wrong as 3 long and 2 short stamens are clearly seen. All features point to B. x blakeana, but I think the pod shown by Raman ji in another thread needs to be closely checked. The pod does not look like any of the two parental species or  other species of Bauhinia. It may well belong to another tree, or perhaps a climber.

Gurcharan ji,
Thanks for the id.
I appreciate your efforts and time taken out in identifying this
Bauhinia species from Lalbagh.

Aarti

[Gurcharan Singh]

If this tree is same as one uploaded by Raman ji, then perhaps comments in the other thread have to be kept in mind.

Gurcharan ji,

Thanks for trying to identify my Bauhinia from Lalbagh.

Hoping to take more pictures when I visit next time.

Ranjini ji has also posted pictures of a Bauhinia tree earlier. It could be the same one.

Aarti

[J.M. Garg]

Taking it as Bauhinia variegata as per another thread:

Garg Ji,

Thanks for the update.

Many of us had thought it to be Bauhinia blakeana earlier.

Regards,

Aarti

[Gurcharan Singh]

Garg ji, the label is misapplied. B. kurgii is now considered as synonym of B. monandra which has flowers with marrower pink petals, only one posterior petal is red and most important has only 1 fertile stamen. 

But it does not look like B. x blakeana also as there are only three well developed stamens, other two seem much smaller. Most important leaves don't seem lobed (1/3 to 1/2 in purpurea; 1/4 to 1/3 in blakeana and variegata)
