Datura innoxia or Datura wrightii?
How to differentiate between both?

[Anurag Sharma]

My mistake, I meant to type Solanaceae and not Convolvulaceae.

Perhaps the difference lies in the distribution! Or maybe in claims :-

1. Datura meteloides Dunal (see FoI) is ... actually a syn of D. inoxia Mill., a Mexican plant having narrower flower with 10 teeth - http://en.wikipedia.org/wiki/Datura_wrightii#Other_names
2. D. wrightii Regel .... is conspecific with inoxia - http://ucjeps.berkeley.edu/cgi-bin/get_IJM.pl?tid=22389
3. a variety or ssp. as in http://www.calflora.org/cgi-bin/species_query.cgi?where-calrecnum=2622 or in http://plants.usda.gov/core/profile?symbol=dawr2

Please wait for inputs from US.

Thanks and regards

Dear Anurag Ji,

You asked this question about 8 months ago! I responded without knowing anything. Here is the answer -

• http://www.flora.sa.gov.au/efsa/lucid/Solanaceae/Solanaceae%20species/key/Australian%20Solanaceae%20species/Media/Html/Datura_wrightii.htm
  
• http://www.flora.sa.gov.au/efsa/lucid/Solanaceae/Solanaceae%20species/key/Australian%20Solanaceae%20species/Media/Html/Datura_inoxia.htm
  

The above links tell me that unless a whole population is studied it is impossible to differentiate the two species. Please also check http://wnmu.edu/academic/nspages/gilaflora/datura_wrightii.html. Unfortunately the paper http://www.publish.csiro.au/paper/BT9760415 is not freely available.

Thank you

Regards

surajit

Garg Sir

Can you please provide, in our database, the exact BSI list of  Indian Datura, all species and their synonyms?

On what basis this site claims - "Datura metel of India resembles this plant"?

Thank you

Regards
