Common name: Devil’s Trumpet, Horn of plenty; downy thorn apple, Safed
dhatura सफ़ैद धतूरा (Hindi), Sagol hidak (Manipuri), Ummata (Malayalam), மாதுளம்
Madulam (Tamil) ;
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

Requesting to please provide ID of the Datura plant captured at MNP in April 2014.

The fruits did not have pronounced spines.


I think this is Datura metel L.


Yes, I agree with …


yes


Thanks … for the ID…

I have posted another Datura metel, but the spines on the fruits of that plant were quite pronounced, hence the doubt…
Do the spines fall off eventually?


…, the KEY in FoC explains your query- “Plants glabrescent; capsules tuberculate or with stout-based prickles”, please also check description.


Thank you … for the link very much…..


Yes D. metel

Hope u r fine and engaged in research…
Here is the attachment of Dhatura sp. I think it is Dhatura metal ?


species level identification cannot be attained by flower pic, however tentatively this is D. innoxia
key to species

1. Corolla 5-lobed with 5 alternating tooth; Fruit with long spines

1. Corolla 5-lobed, without 5 tooth; Fruit tubercled with short spines

D. innoxia

D. metel


I think double flowered form of D. metel only. In D. inoxia the leaves are hairy and with greyish appearance.

Again a small plant.


I guess Datura fastuosa,


What would be the common name for this one?
And how is it different from Datura metel?


I believe this too is Datura metel L. D. fastuosa is a synonym.


If you look at stem, the stem of D. metel is dark purple or blackish, so called kala-dhotra in marathi and D. fastuosa’s stem is greenish called just Dhotra in Marathi.

pls validate

Size of the prickles on fruit leads me to think that it may be Datura metel.
Besides D. stramonium is not found generally wild in tropical areas.


I think u r right Sir


I guess Datura fastuosa L. and its different from D. metel L.


Since a very long time D. fastuosa L. considered as synonym of D. metel L. http://www.theplantlist.org/tpl/record/kew-2757779


 


Datura species:  How do you distinguish between Datura metle and Datura Stramonium?


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


Yo can also take a look at link below from eFlora of China
for the identification key of Datura for further references.

Yes … D metel


yes common worldwide… even if garden are well tended and “OVERSTAFFED” ….
about 30 and then again 20 or 25 years ago found it in well tended garden edge with rocks as mulch … in waiting area of Pirates of Carribean Ride and then again in similar rock chips mulched flower bed of Swiss family Robinson Ride… remember it well since I took the pictures..many people started taking pics, and then next day (we were obsessed with the rides and had Seven day passes/tickets) they were gone and park rangers standing around told us “the plots were de- weeded last nite… ”
even in snow bound NY I find in well tended plots of parking lots of fivestar designer apparel stores… go figure? how do these seeds find their way to such places is guess work at best… I guessed it must come in with the mulch…
In India I find it in road sides, temple grounds, rubbish heaps with stones rocks that are not cleared away for years… do not know how seeds got there, bird poop?
Any other ideas??? Anybody?

I have seen this DHUTURA only in front-yard of a few people, never in the wild. Certainly will take a note in my next find.

Hooghly Today : Datura metel Linnaeus:

“Bengal Plants” describes three Datura species :-
Capsule opening irregularly near apex, usually pendent –
flowers more or less purple ……………. fastuosa
flowers white or cream-coloured ………. fastuosa var. alba
Capsule deeply 4-valved almost to the base, erect; flowers purple stramonium var. tatula

so does it mean one needs to wait till fruits develop and finally burst open to get an exact classification in case of DATURA?


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

Datura metel : 1 post by 1 author. 4 images.
Presenting dissected flower of Datura metel with apparent 4 whorls. Cream colored variety, this was a fallen flower, I didn’t pluck fresh one.
In Surat city. Cultivated.
From left, calyx, first, outermost, smallest whorl, second whorl and innermost whorl, the longest one. 
Innermost whorl looks like it is two, but in reality it is one, long span arranged spirally.
Arranged like a paper cone. And outer surface of second and innermost have outgrowths of same corolla tissue, that appendage held in between my fingers. 
Inner surface.  
Stamens on one side of this span of inner corolla.
This is second time I did this dissection. Outermost whorl is free, and easily gets removed, second and innermost I found stuck to each other, densely in narrower part of tube
patchy in flared part, making dissection delicate work.

There are more observation, I shall share soon. (Currently obsessed with this Genus).
