I found this plant in Rajasthan, India. This sample is 4-5 cm long. This is an ornamental plant. It was a potted plant. I put my fingertip in the photo to give an idea of size of the specimen. I can't figure out which plant this part belongs to. Please give the species name if you can. I would be very thankful to anyone out there who will help me.
This is a bit hard to say exactly, since there is a number of possibilities. We can be pretty sure that these sample is from a Cypress, belonging to the family of Cupressaceae, but which subfamily or species this is exactly, can't be identified here. Therefore a wider image would be necessary, but since this is a potted plant, even this might not be enough, as a lot of these plants are used in gardening.
It is called Leyland Cypress. For more details, refer the following link. https://en.wikipedia.org/wiki/Leyland_cypress
