Green w/one spine down middle from front to back is #16 at Yeamans Hall, the Biarritz hole.
Very tilted green with spine, actually a giant tube, running down the middle from front to back is #5 at Soaring Eagles in Horseheads, NY
Perhaps most famous green with spine down middle front to back is #17 at Pebble, though that green is so shallow, the spine's probably only 25-30 feet long.
