What is the meaning of the phrase "divided at the root".
"This persisted as a doctor of Chinese extraction - long, yellow, and divided at the root - felt around inside her cotton nightie for a non-existent heartbeat." (Will Self: The quantity theory of insanity)
It's difficult to think of a meaning for that. What persisted? (What is 'This'?) Is there meant to a comma after 'persisted'?
