Tecoma fulva (Cav.) G.Don, Gen. Hist. 4: 224 1838 and its subspecies;
 
Cahuato;
 
Tecoma fulva has winged rachis whereas the Tecoma x smithii is wingless;  
As per efi thread:
What we think as T. fulva is a complex with many subspecies and cultivars. Here is a beautiful article on Taxonomy of Tecoma, from Bolivia, South America, native land of Tecoma 
A revision of Tecoma Juss. (Bignoniaceae) in Bolivia by JRI Wood (Botanical Journal of the Linnean Society, 2008, 156, 143–172):

Tecoma smithii. : Attachments (1). 6 posts by 5 authors.

Plant from smriti van Jaipur. It is Tecoma smithii.

Photo Taken on-1.3.2008


I think that this is a lighter color form (perhaps ‘Orange Jubilee’?) than the typically darker-orange T. x smithii (T. stans x T. capensis).


Here is the more typical (at least in the USA) form of T. x smithii:
http://pics.davesgarden.com/pics/Kell_1160332537_516.jpg
Flowers are in large, nodding clusters. This hybrid does come, more or less, true from seed.
Other lighter-colored selections (perhaps F2 hybrids?) such as yours and this:
http://www.biopix.eu/PhotosMedium/JCS%20Tecoma%20smithii%2047104.JPG
are indeed in the trade. I’m certain that your specimen is T. x smithii; I’m just not certain if it is a separate, named cultivar


It is Tecoma fulva


After reading … comments on the identify of Tecoma in question, we together did a bit of research on this issue and found that Tecoma fulva has winged rachis whereas the Tecoma x smithii is wingless. This is an obvious difference between these two taxa. Kindly see the link for Tecoma fulva http://www.meemelink.com/prints%20pages/12834.Bignoniaceae%20-%20Tecoma%20fulva.htm and for Tecoma x smithii for http://www.californiagardens.com/Plant_Pages/tecoma_smithii.htm
Finally we came to the conclusion that … plant belongs to Tecoma fulva.

Identified as T.fulva as it has winged rachis


Yes … u are correct.

Please ID this small tree with yellow flowers. Photo was taken in Sri Lanka in Sep 2012.


Tecoma fulva.


 
Yellow trumpet flower is a variety of Tecoma stans, the Yellow Bells.
It has narrower and lacy leaflets which are more deeply toothed. The name angustata means narrowed. This is a shrub or small tree that reaches 15-20 feet in height and can be pruned heavily after flowering to keep it compact. The fruit on is a “bean type” capsule about 8 inches long that ripens to a chocolate brown color.
It is Tecoma fulva as per keys and details herein.
Tecoma stans var. angustata looks different as per details herein.

Grows in Mumbai


Loos like Tacoma smithii
Bignoniaceae


efi page on Tecoma fulva & Tecoma x smithii  


This is Tecoma x smithii


It is Tecoma fulva as per keys and details herein.


As the rachis appears to be winged, it should be Tecoma fulva as per keys and details herein.


I believe it as Tecoma fulva and had been clarified years back.


Yes ID seems correct for me.


Tecoma is a beautiful ornamental, hence many cultivars available. We can not make a definite ID routinely other than T. stans , T. castanifolia and T. capensis ……………..what we think as T. fulva is a complex with many subspecies and cultivars.

Since I saw you are updating/reviewing some of the Tecoma Species, I’m posting these pictures taken last month.
A cultivated bush seen in Muscat on he 20th of April.
It was evening time and I could not get better pictures.
Had thought of revisiting the place to click better pictures, but not able to go as yet.

Pl. check with Tecoma fulva 


Thanks … I will check.

Campsis Species, similar to the one posted by me earlier.

Campsis radicans was suggested by me.
This was a small, potted plant.
Seen yesterday at Lalbagh.

More like Tecoma fulva … Many cultivars in it. Actually we are not very clear on Tecoma species beyond T. stans and T. castanifolia.    


You had suggested Tecoma fulva earlier.
Can it be Tecoma fulva subsp. guarume?

I found the keys on net from A revision of Tecoma Juss. (Bignoniaceae) in Bolivia by JRI Wood (Botanical Journal of the Linnean Society, 2008, 156, 143–172) as below:
KEY TO TECOMA SPECIES IN BOLIVIA

5a. Corolla 4.5–5.5 cm long; leaflets weakly toothed, teeth three to four per centimetre………………f. ssp. garrocha
It is very difficult to see many details with your very small images. However, Leaf rachis appears to be winged and I see 7 leaflets. So ssp. guarume is possible.
Pl. check the above keys in detail.
It appears close to images of ssp. guarume seen at TechieOldFox and Flora and fauna website, but looks different from those at Kew Database.


Thanks … I had suggested the same earlier.

Will attach the pictures one at a time.

Yes, possible.
