Corolla 3-5 mm long in former, 6-9 mm long in latter. fruiting calyx 4-5 mm long in former, 5-7 in latter. Both are herbs with fruiting calyx ascending or spreading, upper calyx lobe circular with wings decurrent (joined) to middle of calyx, and front two teeth of calyx quite distinct.

Wild growing Tulasi among Alternanthera thicket.
Place: Vaghbil, Thane
Habitat: near creek
Date: 28 NOV 09
A few shots of lateral and lower calyx teeth should be helpful.
IT may be Ocimum canum. as it hav corolla purple in colour… others who r experts plz verify..
According to GRIN as well as eFlora of Pakistan, O. canum is now correctly known as O. americanum.
… attaching another photo … couple of close-ups of the calyces.
I think this matches with the plant posted by me few days back IDed as Ocimum basilicum L. var. pilosum (Willd.) Benth. …
The two photographs now sent by … clearly establish broader lateral calyx lobes, and non-approximate front teeth. They point to O. americanum or O. basilicum. Leaves in … photographs appear distinctly smaller than those sent few days back by …. If leaves are smaller than 2.5 cm and narrower than 2 cm and corolla shorter than 5.5 mm, it is O. Americanum, if longer than 3 cm and corolla longer than 6 mm it would be O. basilicum.
Perhaps we can explore more.
I request you to kindly have relook at your specimens. Whereas the specimens posted by … clearly belong to O. basilicum var. pilosum, your plant to me looks to be with smaller leaves. Since we are desperately looking for authentic specimens of O. americanum, I request you to kindly observe the size of leaves, length of corolla, size of calyx in flower and also in fruit to allow us to reach any conclusion. O. americanum just a mini version of O. basilicum.
I just returned from the site — deprived of its share of nutrients by the dominating Alternanthera plants, the Ocimum plants are drained of all its sap.
Regret having not digged deeper at the earlier instance.
Next Ocimum time, will remember your points.

Stevia rebaudiana ? Sweet tulsi – Seeni tulsi in Tamil
Location : Chennai outskirts
Elevation : 20 mts.
Habitat : cultivated
Habit : Short herbal plant
instead of flowers please post full face on photos of the leaves both front and back. more the merrier
Not Stevia rebaudiana, which belongs to ASTERACEAE. If you eat the leaves it will be very very sweet. A substitute for sugars. Powder of the leaves/ extract sold in markets. Very costly.
Appear as some species of Ocimum (Lamiaceae); not Stevia. Please compare with available species of Ocimum in eFI at-https://sites.google.com/site/efloraofindia/species/a–-l/l/lamiaceae/ocimum
