This appears to be a Tabebuia species-not T.aurea or T.spectabilis. Had sent other pics of same flowers & leaves last year too but did not get
a conclusive ID. Do not have pic of trunk. Pic taken in Lalbagh, Bangalore on 14-02-10 at around 9.30am. Request once again for ID.

the plant in the attached photo may be Tabebuia chrysotricha.

---

I doubt it … Someone else had suggested the same & provided this link:

http://toptropicals.com/cgi-bin/garden catalog/cat.cgi

I found T.chrysotricha after ‘Tabebuia search’. I find the leaves of T.chrysotricha are very different from the leaves of the Tabebuia in
the picture i have sent   

---

Your asumption can be true, I will wait to see the ultimate name of the plant.

---

Is it Tabebuia argentia.

---

It is definitely not T.argentea. I noticed i had repeated one pic instead of giving a pic of leaves. I have corrected it this time.
I’m putting up the link once again.

After a confusing investigation I say that this may be T. chrysantha looking at the elliptic-lanceolate and membraneous leaves

---

Agreed, not T. argentea. It is not one of the Tabs I’ve seen before. Has anyone investigated T. serratifolia?

---

I tend to doubt T. chrysotricha (now Handroanthus chrysotrichus) because of the apparent glabrous foliage. It looks closer to H. umbellatus (T. umbellata), but even that I’m not certain of.
I forwarded to others who may be of assistance. If I hear any response, I’ll forward.

---

I also think it is T. Chrysantha
Since it has leaves palmately compound with 5  leaflets.
If the tree is 5-6 m high then its T. Chrysantha for sure.

---

Here are a couple of pics of Handroanthus (Tabebuia) guayacan, umbellatus, and serratifolius (all yellow-flowered spp with glabrous foliage) showing rather distinct branching habits and inflorescences in the presence or absence of foliage.

Unfortunately, these pics are not very clear, but they may provide some help nonetheless. Of these three yellow-flowered species, the only one I’ve seen/touched in person is H. umbellatus, and though that is a possibility, the other two species merit additional investigation, IMHO.

---

Handroanthus (Tabebuia) guayacan a member of Bignoniaceae bears a very beautiful flowers. Have you seen it in flowering stage? Bright yellow flowers ?

---

The first mail i had sent in this thread has pictures
of the flowers.

Some [many!] more pics of the same tree [taken on o4-04-2010 at Lalbagh Botanical Garden] Looks like T.chrysantha going by close-up of leaves? Attachments (7)

Request ID for the tree bearing these flowers + leaves. Pic taken at Lalbagh Botanical Garden, Bangalore on 080209.

---

A Tabebuia species, though I’m not certain which one.

---

Tropical Garden Plants by Bose, Chowdhury & Sharma gives two such species Tabebuia chrysantha (Beautiful dwarf tree with five ovate leaflets) &  Tabebuia donnell-smithii (medium sized tree 8-10 m, with 5-7 ovate leaflets). 

---

The foliage does not look like T. donnell-smithii (Cybistax d.)
I haven’t seen T. chrysantha  personally, so that may be it. (Other yellow-flowered species it is not are T. aurea/T. argentea, T. chrysotricha, T. umbellata.)

Name given is Tabebuia spectabilis.

No flowers when the picture was taken.

Leaves look similar to another Tabebuia posted by me recently with couple of yellow flowers

Thanks for confirming the id.

My other Tabebuia from Lalbagh, could be the same.

I will resurface it.
