Bignoniaceae Week: looking for Campsis grandiflora:
Thank you, nice to remember these differences, but what confuses me more is the vast numbers of cultivars that I see in India and in American southwest and in Florida.
Garden breeders and cultivar developers have to keep busy to give some thing new to the plant lovers.

Let us locate Campsis grandiflora
Most of us following Indian Floras and famous “Manual of Cultivated Plants” by L. H. Bailey, know two cultivated species of Campsis:
1. Campsis radicans (L.) Seem: Leaflets 9-11, pubescent beneath especially along veins, calyx split less than 1/3, corolla tube 3 times as long as calyx, fruit 7-12 cm long, beaked at apex.
2. Campsis grandiflora (Thunb.) K.Schum. (syn: C. chinensis (Lamarck) Voss): Leaflets 7-9, glabrous beneath, calyx split 1/2, fruit 12-15 cm long, apex obtuse, not beaked.
I have explored many parts of India and found that whereas C. radicans is quite common especially in Kashmir and Delhi, areas I have explored most, but the plant which looks like C. grandiflora (and may have been identified by many as C. grandiflora) have 7-13 (rarely up to 15) leaflets, glabrous beneath, calyx split nearly 1/2, corolla tube about twice as long as calyx, Interestingly this does not produce any fruits, the whole flower falling off early along with the ovary, reason being that this plant is a sterile hybrid between the previous two species, and can be spread by cuttings. It has been named as C. x tagliabuana Rehder, and has a number of cultivars.

I have been unsuccessful with C. grandiflora
Members are requested to look for plant of C. grandiflora (7-9 leaflets, glabrous beneath, calyx slit half way, corolla tube slightly longer, and very important with fruit.
Let us hope we are successful
