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

Sadadhutura : Attachments (1). 5 posts by 3 authors. I hope you are right May you please check with Datura ferox once again.? It is difficult to distinguish between the two sp. from Photos, but D. ferox is an introduced sp., unlikely to be found in a remote village of Bengal. 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. Could you please locate plant with fruits? . |
