Not a pocket guide, quite a brick, but good for cross-reference.

Collins Pocket Guide: ‘Grasses, Sedges, Rushes & Ferns of Britain & Northern Europe’ by Richard Fitter, Alastair Fitter & Ann Farrer (Collins, 1984. Reprinted many times).
Has colour illustrations with line drawings of detail, but I find the colour pages rather crowded. It has what it calls a Single-access key by which you check against a list of characters to narrow down your search. Plenty of copies available second-hand, ranging from £6 to £107.

Rushes by Wallace, Roberts & Lawrence (Field Studies Council, Wild ID fold-out card, 2018). Colour illustrations of 32 rushes (Juncus) and wood-rushes (Luzula) with a lateral key for each of these. Colour illustrations with magnified views of key diagnostic features: flower heads, stem pith and seed shape.

Websites

Google Lens: Go to google.com and there is a camera icon at the right of the search bar. Click on this, and you can drag and drop any image and it will do its best to identify it – so can be used for any flora and fauna, vertebrates and invertebrates etc. (as well as buildings, landscapes – anything, in fact.)  Worth a look, but treat identifications with caution!
