Liya-pata is a type of Sinhalese decorative work that is best described as a series of fine scrolls that are themselves covered in more tiny scrolls, and so on.

"This exceedingly conventional foliar ornament deserves particular study. It is more characteristic of Sinhalese design than any other form; instruction in the use of it is almost the first thing taught to young craftsmen."
"Work filled with it is called liya-pata-vẹḍa; a single element would be called gẹṭa-liya-pota..."
"...it occurs especially in knife handles (...) It is very characteristic for metal and woodwork, It is often found on wooden pillars at the transition from square to octagonal section. It is constantly used in the tails and crests of conventional birds and bird-like tails of mythical animals, and, in fact, everywhere."
