In both D. stramonium and D. metel the plants are glabrous, hairy in D. inoxia
The deciding difference between D. metel and D. stramonium is that mature fruit of D. metel is drooping, covered with short blunt tubercles barely exceeding 3 mm; in D. stramonium mature fruit is erect covered with long spines up to 5 mm long.
In addition the following may help. Plants of D. metel are generally taller less branched and erect often reaching 1.5 m and tend to have purplish stem, in D. stramonium plants are shorter, more branched and spreading, stems not purplish.
The leaves of D. stramonium are generally parted, whereas they are not parted in D. metel
Luckily you can distinguish them from vegetative plants and flowers also.
1. Plants glabrescent; calyx 5-angled; corolla less than 12 cm long; leaves sinnuate-dentate, anthers less than 5 mm long (capsule erect, 4-valved, with stout up to 5 mm long prickles)…D. stramonium
1a. Plants glabrescent or hairy; calyx cylindrical; corolla more than 12 cm long; leaves entire or sinuate but not
dentate, anthers longer than 1 cm (capsule deflexed, irregularly dehiscent)… 2
2. Plants gladular-pubescent, not purple; calyx 8-10 cm long; corolla 15-18 cm long, anthers 10-17 mm long (capsules deflexed, covered with slender prickles, pubescent, irregularly dehiscent)………………….D. inoxia
2a. Plants glabrescent, often purple; calyx 4-9 cm long; corolla 14-20 cm long; anthers 10-12 mm long (capsule deflexed, with short broad-based short prickles, irregularly dehiscent)……………D. metel
The two species can be conclusively differentiated from fruits and seeds. The capsules of D. ferox are on erect stalks, lower spines are much shorter, upper longer, seeds black or grey. In D. inoxia capsules are on recurved stalks, spines almost equally longer, seeds yellow or brown
Flora of Panipat- Datura innoxia from Village JATAL Panipat roadside area:
From Jatal Panipat roadside area, Wild no fragrance
IDENTIFICATION OF FLOWER: (mixed thread): 1 correct image as above.
Could your group of experts please help identify and describe this wild
flower i photographed behind the sukhna lake in chandigarh. The area falls in the foothills of the lower shiwaliks and these flowers have just bloomed. I am writing about these flowers in the newspaper and would require your expertise.
Strangely, theplantlist ( http://www.theplantlist.org/browse/A/Solanaceae/Datura/) lists this in two
different spellings D. inoxia and D. innoxia, both as accepted names, with same author. However, one is presently ‘in review’.
I hope Datura inoxia

Datura innoxia or Datura wrightii?
My mistake, I meant to type Solanaceae and not Convolvulaceae.
Perhaps the difference lies in the distribution! Or maybe in claims :-
Please wait for inputs from US.
You asked this question about 8 months ago! I responded without knowing anything. Here is the answer –
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”?

I am afraid spines prove nothing. Fruits are different in FoZ –
I don’t find any contradiction with links provided. The last link identification has to be still verified by experts as mentioned on the website. My experience is that plants of D. inoxia are pubescent so that older plants especially along roadsides become dirtier, capsules are usually deflexed with slender spines. In D. metel plants are glabrescent and stems and leaves usually shining, fruits usually erect with short blunt tubercles much more stouter than D. inoxia.
Thanks … for raising your doubts which led to suitable explanation, thanks … for confirming the id..
(i) stamens not exserted; stigma well below anthers; spine on capsule upto 10 mm long; persistent base of calyx upto 20 mm long = inoxia
(ii) stamens shortly exserted; stigma above level of anthers; spines usually 3-5 mm long; persistent base of calyx to 10 mm long = wrightii

Your help needed to identify this plant.
Height:about 3-4 ft.
Datura species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available on net)
It seems to be Datura ferox, Pandhara Dhotara, Family- Solanaceae.
looking at the fruits its certainly not D ferox, close up of fruits might help in identification
There are two species which are very nearer to each other Datura metel and Datura ferox. There are no purplish flowers.
So it may not be D. metel.
But the white flowers and sharp thorny fruits indicates towards the Datura ferox only.
I have attached 2 closeups of the fruit. I believe D. ferox has unusual long spikes. To my untrained eye this looks more like D.inoxa. yes thanks for your opinion appreciate it.

please identify the plant in picture. The snaps wee shot outside the Jahapanah City Forest, Delhi.
First photo belongs to Datura sp. and the second can be a Vernonia sp.
Few more shots of Vernonia.
Datura maybe Datura innoxia Mill., due to pubescent leaves.
D. wrightii has not been reported from India as per details at Datura.
It is possible that D. wrightii may be a syn. of D.innoxia, as per
I think you are right.
