Field notes
The guide distinguishes leafy gall as a tight mass of small, distorted shoots, normal growth as separate shoots on their own stems, and crown gall as a solid irregular swelling. It recommends a daylight close-up centered on the crown and warns that a distant flower photo is not useful. Reference-photo credits and diagnostic resources are linked from the page.
