myrtle

I'm a little stuck... Click here to teach me more about this clue!

'girl' is the definition.

I don't understand how the remainder of the clue works.

(Other definitions for myrtle that I've seen before include "Evergreen shrub with dark purple berries" , "Evergreen shrub with blue-black berries" , "Shrub with purple-black oval berries" , "Girl" , "Shiny evergreen shrub" .)

I've seen this clue in the Evening Standard.
