Please help to ID this Bignoniaceae Climber
Generally blooms when temperature drops and usually flowers last for 2-3 days only.
Super clear pics. Try Cydista aequinoctialis…now renamed Bignonia aequinoctialis
I think more closer to images at Mansoa alliacea
Thanks for the lead …
But the description of Cydista aequinoctialis as per Flora of Micronesia, 5 :-
Extensive vine, lacking garlic odor, leaflets large, ovate, tendril simple often much exceeding leaflets; inflorescence a twice or more trichotomous terminal panicle; flowers funnelform, throat yellow within, brownish outside, lobes lavender or pink or whitish with purple markings; fruit a large stiff brown dehiscent strap-shaped pod; seed body small, wings extending several times its width.
In this case tendrils are trifid. Moreover ‘throat yellow within, brownish outside’ doesn’t match. Inflorescence ‘twice or more trichotomous’ is also not matching. Not sure if these can be local variations.
Can’t be Mansoa alliacea as it lacks garlic odour. Infact I have both these climbers in my backyard so it’s easy to compare.
In that case, Cydista aequinoctialis is more likely. Both are quite confused.
The climber has been identified as Mansoa difficilis (Cham.) Bureau & K. Schum. by Dr. Lúcia G Lohmann, University of São Paulo, Brazil.
