What is this close-up picture? (WotsThat: Thorn bush texture (macro))

Question

What object is shown in this zoomed-in close-up photo?

Thorn bush texture (macro). Botanically, true thorns are modified stems, while prickles like a rose's are modified skin cells and spines like a cactus's are modified leaves, so thorn is technically the wrong word for most spiky plants.
