Tapestry just means fabric woven or embroidered with scenes or designs. It can be made by hand or woven on a type of loom called a jacquard loom. I think tapestry is the popular term for that kind of upholstery fabric because it's easy for most people to remember, but the technical term is jacquard. I think there may be a third term too but I can't think of it right now.
The particular floral pattern in your photo would have had a unique pattern name picked out by the marketing department of the manufacturer. Or maybe just a number. I think "floral tapestry fabric" is fine if you're just trying to figure out how to describe it in a for sale listing.
