Tecona stans – Yellow Flower:  The subject line for this post has broken at some point/s, I guess.
Therefore, I am changing the subject line to the first upload and giving links for related discussions.

I am extremely sorry that I couldn’t reply in time as I was not accessing email for last 2-3 days.
Yes I got your mail and let me correct myself on one aspect that, in T. castanifolia the leaves are not strictly simple but mostly simple and sometimes, especially at the tip leaves are tri-foliate.

I hereby provide the key for Tecoma as seen in Bhat K G (2003) Flora of Udupi.

Leaves simple or 2-3 foliolate…….. T. gaudichaudi (now, T.castanifolia)
Leaves 5-13 foliolate ……………….. T. stans 

Please visit the following site for a video in which bees (Apis cerana) visiting the flowers of T. castanifolia. In this video we can see most of the leaves are simple and the flowers are clustered (inflorescence) at the tip.

http://www.hear.org/pier/species/tecoma_stans.htm (please visit this link for a comparison with T. stans)

The pictures in your last mail shows that the leaves are tri-foliate in that case your plant could be Tecoma castanifolia (hoping that the basal/other leaves are also simple or tri-foliolate not 5-13 foliolate, please confirm this).

Confusion always arise when there is no information related to the plants are available. Therefore, I once again request all members to provide as much information on the plant as you can along with the id request.

Many thanks for the wonderful video of bees collecting nectar.
… has said that it is T. stans.
For comparison you referred to article which describes ‘leaves opposite,  pinnately compound [Pl. explain], leaflets 1-9, usually 3-7’. I told you I  am anovice. I had to learn what is a compound leaf. I saw a few illustrations in the net in which trifoliate is shown as compound. Pl educate me if you have time.In my previous letter to you i said that the height of the tree is about 4 metres which is what the net describes. For castanifolia net says “6-8” m which is definitely not. Why dont you look  from this angle also?
I understand my last submission is not coming for public. I wanted people  should be aware that it may be used as ornamental trees on the roads in  campuses.

Yes as you learned 3 foliolate leaves are also compound leaves. At first I learned that T. castanifolia has simple leaf then I referred more literature from our library and understood that it can have trifoliolate leaves as well along with simple leaves.

To me 4m and 6-8m doesn’t make much difference, rather I would consider the place where it grows as height of plants mostly depends upon availability of light and cluttering with other plants. If the plant stands alone there are chances that it might be smaller than that of another individual of the same species that grows in a clutter.
One thing that would certainly clarifies about the species is the number of leaflets in one leaf stalk.
If there are 5-13 leaflet in one leaf stalk it would be T. stans, otherwise it can be T. castanifolia.

In south India T. stans is common and the other species is not as common.
I will send you few illustrations of morphological characters of plants in another mail.

I was waiting for the illustrations you promised.
An error has crept in the title. It is Tecoma stans.
As per your suggestion I went ( Location-Kolkata ) and verified ;
leaves are not simple. They are trifoliate and opposite. You quoted RG Bhatt(Flora of Udupi)
Leaves simple or 2-3 foliolets – T. castanifolia
Leaves 5-13 foliolets             –  T. stans.
Hence this cannot be uniquely identified . However I would like to draw your attention to another specification from PIER for T. stans “Shrub or small tree (one ref mentions 4m high) — Leaves OPPOSITE, pinnately compounded, leaflets 1-9, usually 3-7  – – “ This lends support it to be T. stans
