I am having difficulty in choosing between B. grandiflora and B. pauciflora. The defining character is calyx only 12 mm long  and flowers more than 5 in a cluster in B. grandiflora and flowers 1 or more and calyx 25-40 mm long in B. calycina. At least your second photograph (blue flower) could belong to B. pauciflora.

Thank you very much Gurcharan ji for validating the ID.

If one of the flowers (the 2nd photo showing blue flower) seems to be B. pauciflora - the 3rd and 4th also would be same - belonging to same plant The blue colour fades to white as flower loses its glory. 

Only the first one is from different plant, though the flower size I remember was same as that of blue; perhaps a different cultivar of same species.

Let me put a cropped version of last photo to show some hint of calyx; but I do not remember its size. 

 

Regards.

Dear Sir,

 

It is difficult to identify over images based on keys mentioned below, so Mr Dinesh Valke Ji knows the exact characters of plant, it would be easy to him to identify species based on characters mentioned below:

 

 

Key differences in Brunfelsia grandiflora and B. pauciflora:

 

Brunfelsia grandiflora

 

Leaves usually 16-31 cm long, scattered, with 5-9 lateral nerves, less than 8 cm wide

Inflorescence lax, often short-branched, flowers 5-many, showy, scentless, violet fading to white with age, with rounded, white ring at mouth,

Corolla tube 2-5 times as long as calyx,

Corolla tube 15-40 mm long,

Corolla lobes spreading at anthesis

 

Brunfelsia pauciflora

 

Leaves usually 2-15 cm long, oblong to oblong-lanceolate, with 5-11 lateral nerves, membranaceous to subcoriaceous

Flowers 1-many per inflorescence; terminal, sessile or subsessile, with 1-11 flowers,

Pedicel 11-25 mm long, showy, deep, reddish purple fading to pale lavender or white with age, with white spot at mouth sometimes edged with violet.

Calyx glabrous or with sparse glandular hairs,

Corolla tube 1-1_1/2 times as long as calyx,

Corolla tube 25-40 mm long,

Many thanks Garg ji for resurfacing this post.

Thank you very much Varun ji for providing the characters of both the species.

Posted plant agrees with most characters of B. pauciflora ...

The leaves were less than 15 cm; they were not large leaves.

Flowers were mostly single per inflorescence.

I am convinced the posted plant is B. pauciflora.

Regards.

Dinesh
