I would go with O. americanum based on shorter corolla, slightly longer than calyx and more hairy calyx

Thanks for reproducing this key. It would really help in fixing our specimens of Ocimum.

[Gurcharan Singh]

The key I find is confusing for lack of formatting. I am reproducing after formatting. I also notice that First lead is redundant (atleast for SE Asian species) unless the key is only a part of original key and all SE Asian species share the common features of distinct teeth of lateral calyx lobes, deltoid or lanceolate in shape and bract without bowl-like gland developing. 

 

Key to continental SE Asian species of Ocimum

Is it not Ocimum basilicum var. pilosum?

Yes Vijayasankar ji

Ocimum basilicum var. pilosum (Willd.) Benth. is the synonym of Ocimum x africanum Lour.

Your conclusion tallies with that of Culhan ji

[Vijayasankar]

Thanks Gurcharan ji.
The name O. x africanum is new to me. I know the plant as O. basilicum var. pilosum. And these names are not yet available at GRIN.
The combination O. americanum var. pilosum in GRIN is confusing b'cos the basionym O. pilosum Willd. is also linked to O. basilicum var. pilosum.
Thanks also to Culhan ji and Alan Paton ji for the id.

Is it possible to get full version of the revision?

Thanks & Regards

Vijayasankar ji

But they are at Kew Plant List, 2010. Where as GRIN treats only limited names, this list claims to be nearly complete, though lot needs to be settled. We may soon be all following this:

Hi,

Thanks a lot for providing the keys Gurucharanji, Pankaj,
but...........I am sending some other photos according to my
observations the plant is O x africanum but the internodes are mostly
showing retrorse hairs and not the spreading ones now waiting for all
expert advise from your side to place it under the correct name O.
africanum or O. americanum

Amit ji

Looking at the scale and calyx, the calyx already seems to be around 3.5-4 mm and would definitely enlarge in fruit. Also the hairs seem to be spreading and not appressed. That fits well with O. x africanum.
