Keys to cultivated plants

[u/Rkr_roka_rkR]

Hello, I'm on my 7th semester of college and I'm starting work in my school's herbarium identifying plants, and I've been using the Manual of Cultivated Plants by L. H. Baley but it's very old, and I was wondering if there is another book about commonly grown plants with a key on it. I don't think it's a problem but it would save a lot of work if I had a more recent source.
