Thanks Tabish ji, 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.
