Catches on small branches (5)

I believe the answer is:

twigs

This clue is a double definition.

'catches on' is the first definition.
('twig' can be a synonym of 'catch on')

'small branches' is the second definition.
(I've seen this before)

(Other definitions for twigs that I've seen before include "Kindling" , "Understands" , "Small branches" , "Catches on" , "Slender (tree) shoots" .)

I've seen this clue in The Telegraph.
