Lemongrass essential oil is produced by steam distillation of the freshly cut leaves,[1] or can be extracted using alcohol. It is believed to help with stress-related disorders, and has been shown to have antifungal and antimicrobial properties.[2] Cymbopogon flexuosus completely inhibits all MRSA colony growth.[3]

Cymbopogon martinii/jawarancusa from Hamdard Herbal Garden, Delhi:
This particular grass was labelled as C. jawarancusa at Hamdard University Herbal garden but looking at breadth of leaves and height of plant I have a feeling that this may be C. martinii and the other plant uploaded by me as C. martinii may in fact be C. jawarancusa. Please give your opinion.

This is Cymbopogon flexuosus

Looking at the complex panicle may be it is C. Jawarncusa. Confirmation require spikelet observation

Cymbopogon flexuosus as per another thread.

Looks like Cymbopogon khasianus. Extreme closeup of spikelets required for identification of cymbopogons.

May I request you to post a high res. image.

2 very high res. images.

Do these high res. images help with regard to your remarks

Not exactly, but better. The lack of clear intracarinal nerves on lower glumes of sessile spikelet and presence of two depressions towards the bottom of the glumes suggests that it is Cymbopogon flexuosus which is yet to open up completely and not C.khasianus.
