As per efi thread :
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
Datura ferox, commonly known as Long Spined Thorn Apple or Fierce Thornapple, is a species of Datura. Like all such species, every part of the plant contains deadly toxins that can kill animals (including humans) that ingest it. Its fruit, red-brown when ripe, has unusually long thorns or spikes.
The species was first described in 1756 by Linnaeus. Ferox means “strongly fortified,” referring to the fearsome-looking spines on the seed pod.
It probably originated in southeastern China. Today it is found in all the warm parts of the earth, where it is regarded as a dangerous pasture weed.
Datura ferox is an upright shrub 1½ to 3 feet high. Its thick stalks often have a red-violet color at the base. All the young shoots are noticeably hairy. The most conspicuous part of the plant is its very wide undulate, irregularly-toothed leaves, which are covered with soft, downy hairs. The yellowish white flowers are funnel-shaped and inconspicuous, and usually do not open completely.

Flower looks unusually small. fruit should help. Leaves suggest. D. inoxia.
Nicandra don’t have petals with acute apex hence there it can be Datura innoxia
Datura innoxia indeed
I think this is close to images and details at Datura stramonium L.
On further checking, I think it may be Datura ferox, as per images and details herein.
