There is a very short section on plants within Aset’s section of the LAGG. The list is a short one and I was surprised not to see some plants mentioned.
The ones mentioned are the date palm (of Upper Egypt), the lotus flower, papyrus (with sweet milk), golden lotus flower and the lapis lazuli plant (I would love to know what this is). There are two other plants listed in ancient Egyptian as the Hn-plant and the nbw-plant (I don’t know what these are either).
The sycamore was not listed, but it most likely is in another section. And the rose wasn’t listed here either, but roses aren’t really native to Egypt so it may or may not be here somewhere.
