i am uploading this species because it is reportedly cultivated in Indian subcontinent. It is similar to B. suaveolens uploaded by Rotesh but as can be seen by comparison that in B. suaveolens the narrow lower part of corolla tube is visible above the calyx tube which is 5-toothed, and the flowers are slightly shorter. In B. candida the flowers are slightly longer, lower part of corolla tube hidden in calyx tube, and the calyx tube split on one side. I am uploading the plant from California with the hope that similar may be uploaded from India also by some member.

Manudev ji

Datura plants are usually herbaceous, flowers less than 15 cm long, usually erect and fruit smooth. Also the calyx splits horizontally (circumscissile) upper part falls off and only basal truncated part persists in fruit.

Brugmansia plants are woody shrubs or trees, flowers longer than 20 cm, and nodding. Calyx does not split horizontally, whole calyxpersists, although it may split vertically on one side.

All former woody species of Datura are now synonyms of Brugmansia

Hi All,

Here are my pics of a street tree in Bangalore.

I think this variety is called "Grand Marnier", probably because of the orange tones.

Regards,

Padmini Raghavan.

Padmini ji

This does not look like Grand Marnier which is a cultivar of B. candida and has yellowish flowers

http://davesgarden.com/guides/pf/showimage/4146/

This one seems to be a cultivar of B. suaveolens. Note narrowed basal portion above calyx and toothed calyx not parted on one side.
