I have an article from 1888 where the author (Gregory) fished about for any other name having been attributed to these, and she ends up after 12 pages calling them 'cork-wings'.

Descriptive, I've never thought about a name for it

I've heard and use "crocodile back", seems to fit it.

Thanks everyone for the input. Using that, I did a bit of digging and it seems there is no specific technical term. In his brilliant winter trees and shrubs book, Schultz simply calls these "corky ridges" and commonly found on minor (field elm) and procera but not on glabra. I picked up a beautiful book fora couple of pounds in a charity shop, "Epitaph for the Elm" , Gerald Wilkinson, and in 160 pages of homage to the elm, the most distinctive word he uses is "corky".  Crocodile back is my favourite so far..
