Learning botany doesn't have to be intimidating or boring.
Herbalists do much better if they learn some basics without getting too caught up in the details.
Being familiar with the veins, shape, edges, and arrangements of leaves and the names used to describe them can be very helpful when reading foraging and wildcrafting guides.
So let's talk about the basics.
The veins of a leaf can help us discern between monocotyledonous and dicotyledonous plants.
Regardless of their arrangements, veins serve several functions:
Parallel venation (these are usually monocots) meaning the veins run from the base of the leaf to the tip without branching out an touching each other. Grasses have this venation.
Net-like, also called reticular venation, (these are dicots) which means they will have small branching veins running out of the primary veins.
