Ocimum for ID 20072013 CS1 : Attachments (3). 6 posts by 3 authors. WE had bought a few species of Ocimum for our research. WE are now unable to differentiate between the species. Can some expert please help?

May be Ocimum gratissimum of Lamiaceae; common names- clove basil & wild basil.

Thank you … for the Id. The first one is O. gratissimum , but the second and third images are different I think

True, the first is O.gratissimum, but the second and and third are not.


Ban Tulsi. : Attachments (1). 7 posts by 7 authors.

This plant was growing on our wasteland.
It smells like basil.
May I request you to please help in ID of this plant.

Is it Ocimum basilicum?

I think O. gratissimum

too me it looks like O. americanum

It looks like sabja plant from which we get the Sabja seeds used in falooda.

I think … is right

I think this is a hybrid between O. basilicum X O. americanum, so the name should be Ocimum x africanum Lour. But I am not sure. What do you think?

Ocimum gratissimum


Ocimum americanum L., Cent. Plant. 1: 15. 1755.
After lot of searching I finally was able to photograph O. americanum yesterday from Herbal Garden in Lodhi Garden, Delhi. The plant with general habit of O. basilicum (with touch of O. sanctum) has distinctively smaller flowers.

this ID needs reconsideration

All other photographs at the species page appears OK except this one.

Appears more close to Ocimum gratissimum L. as per images and details herein.

Yes, … That’s why, I had asked for reconsideration.

Ocimum sp for id from TDL Herbal Park Yamunanagar (280 mts)
This shrub was about 4 feet high with strong fragrance. leaves large than usual O. sanctum
Cultivated their as medicinal plant

looks like O. tenuiflorum “Shyama tulsi”

can it be Ocimum gratissimum, the clove-smelling one?

i don’t remember the smell exactly but it was somewhat different from our home tulsi

These images are from … and appear to be close to images at Ocimum gratissimum L., as initially suggested by …


Lamiaceae & Verbenaceae Week : 110711 : AK-2:
Ocimum taken at Maharashtra Park, Mumbai on the 10th of May, 2009.

Any chance for Perilla ??

Or can it be Teucrium canadense (though the flowers are not visible in this pic)

It is a Species of Ocimum only.

This has been identified by …, ex Deputy Director of the Maharashtra  Nature Park, as Ocimum americana, an invasive plant.

I think more closer to images at Ocimum gratissimum L. rather than Ocimum americanum L.

Ocimum Species : Nasik : 07JAN22 : AK – 09:
Seen at the same plant nursery.

These plants were short ones, compared to other Ocimum Species.
Name was given as Pandharpuri Tulsi.
The leaf had a peculiar taste.

Appears close to images at Ocimum gratissimum L.


Ocimum Species for ID : Nasik : 06JAN22 : AK – 06: 4 images.
One more Ocimum Species from the same plant nursery.

The name in Marathi was given as Lavangi, that is the flavor of cloves.
The leaf tasted exactly like a clove.
For Species id please.

Pl. post high res. image of the last one.
It may turn out to be same as at Ocimum Species for ID : Nasik : 06JAN22 : AK – 05

This had a distinct taste of cloves.
Not like the other one.
I will try to get the botanical names.

Clove basil is Ocimum gratissimum L.
Maybe this one, though leaves look a bit variant (may be due to hybrids).

There are a few Scholarly articles on Ocimum Species with leaves having the taste of clove.
Very confusing.
