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.
Those scale-like green structures are likely to be the foliages of Platyclaudus species, they are attached densely on the branches of the plant. Hence the whole thing in your picture shall be the branch with the leaf from some kind of gynosperm tree. It's common in Gynospermum the foliage is highly abbreviated and deformed(comparing to Angiosperm).
It is called Leyland Cypress. For more details, refer the following link. https://en.wikipedia.org/wiki/Leyland_cypress
