It would be interesting to explore further. Second volume of Flora of India published in 1993 describes both C. adansonii subsp.odora and C. religiosa. All characters seem to be similar even leaves in C. religiosa are tapering to abruptly acuminate (abruptly acuminate in subsp. odora). The only significant difference is fruits being orange-yellow turning red in latter (subsp. odora) and grey to brown in C. religiosa.
I have clicked photographs of tree from Delhi that has flowers on both leafless shoots and those with leaves, fruits orange to red. The is very similar to above. Both may be C. adansonii subsp. odora
