Catalpa speciosa from California: A big tree from Bignoniaceae : Observed in Mountainview ; planted on 8th Jun 2011
I am not too sure but this may not turn out to be Catalpa bignonioides. Perhaps … can recollect and apply this key more accurately:
For the key as well as the info about Vicariaceae.
Very true .., leaves put me in some doubt as they appear to be intermediate, but if you can see the plant again leaf size, number of flowers in infl., length of infl. and fruit width can be conclusive. lobed leaves rather suggest C. bignonioides. Who knows it may be a hybrid of two as genetic barriers between the species seem to be week in this genus.
This flower has such amazing colouration!
Bignoniaceae Week: Catalpa ovata from Kashmir: Catalpa ovata G. Don, Gen. hist. 4:230. 1837
Common: Chinese catalpa
Asian counterpart of the pair of vicariant species (American counterpart being C. bignonioides). Deciduous tree up to 10 m tall; leaves opposite, ovate-cordate, 12-25 cm long, abruptly acuminate, sometimes 3-5-lobed, finely pubescent; flowers pale yellow, 20-25 mm long, in many-flowered up to 25 cm long panicles; corolla with orange stripes and dark violet spots inside; pod up to 30 cm long, 8 mm broad.
Commonly planted in Kashmir. Photographed on June 16, 2010 from Srinagar, Kashmir.
The flowers are just brilliant!
I think this should be Catalpa bignonioides, and not C. ovata.
Thanks …, I will have to go deeper to decide finely, because although flowers in most books are usually described as pale yellow, there are majority white flowers if we search C. ovata on net., nor is 3-lobed leaves a consistent feature, although some leaves have two slight projections in upper part. I did not pay much attention earlier because we had read about C. ovata (Asian species) and C. bignonioides (An American species) as classical example Biogeographical Vicariance. The two are very closely related and grow in different continents, although now they have been planted world around. At this stage I am more inclined towards C. speciosa, because of long acuminate leaves, they are abruptly acuminate in C. bignonioides.
I was generally looking at the comparison here:
You are right that images on the web are not very consistent. I would be happy to know what you finally settle at after a deeper analysis.
Thanks, … for digging out the old thread.
Catalpa speciosa without any doubt now.

Please help me to identify.
Is it Catalpa bignonioides..?
I second …
yes. flowers reminiscent of catalpa but the flower spike usually triangular pointing up like kings hat. buy these are not and leaves are usually very large. these seem not not to be. where was it growing??? wild or in botanical garden etc etc
and dear god dont let be dont t from whats app and have no informaion!!!!!
Yes. … is correct. I have seen this plant in one of the botanical gardens in Princeton, USA
Where was it clicked ?
Though to me also appear close to images at Catalpa speciosa
It was clicked at or near Chandigarh by Dr Satish Narula
Even I have asked more images for it.
Catalpa bignonioides in FOI : 2 posts by 2 authors.
Thank you … for bringing this up.
According to the comparative key of the two species given in the discussion in the efi link, the leaves of Catalpa speciosa are typically larger than the flower panicles, whereas the leaves of Catalpa bignonioides are typically shorter than the flower panicles.
In our plant on FOI the flower panicles are longer than the leaves.
