I do not know that one but adding it to my pile. :) I lean more ecology and systems, so I am sure there are some other good recs out there.

Where to find: https://annas-archive.org/ - DM me if you want the audiobook or cannot find it (that goes for anyone).

• Anything by Robin Wall Kimmerer, notably Braiding Sweetgrass (most popular) and Gathering Moss (my fav)
• Changes in the Land: Indians, Colonists and the Ecology of New England by William Cronon (Love this one; it is a classic)
• Nature’s Ghosts: The world we lost and how to bring it back by Sophie Yeo (She refs people I know and like irl; just published - I have not gotten to it but my boss has and says it's good. I trust his instincts more than mine!)
• The Mushroom at the End of the World: On the Possibility of Life in Capitalist Ruins by Anna Lowenhaupt Tsing
• A Sand County Almanac: And Sketches Here and There by Aldo Leopold
• Otherlands: A World in the Making by Thomas Halliday

Also, check out Crime Pays, But Botany Doesn't, a great podcast. I believe he has a book.

This is the book you are looking for:

Botany in a day: the patterns method to Plant Identification

I agree. Especially because Ornithogalum is definitely not an Asparagus kind of plant. If maybe Ornithogalum had been in the Asparagus genus before but got split, well OK. But calling any plant in this pretty diverse family "asparagus", is wild.

The APG II system of 2003 allowed two options as to the circumscription of the family: either Asparagaceae sensu lato ("in the wider sense") combining seven previously recognized families, or Asparagaceae sensu stricto ("in the strict sense") consisting of very few genera (notably Asparagus, also Hemiphylacus), but nevertheless totalling a few hundred species. The revised APG III system of 2009 allows only the broader sense.

Asparagaceae includes 114 genera with a total of approximately 2,900 known species.
