So, I thought it would be interesting to begin organizing plants, especially trees, by leaf venation patterns. As a first baby step, I’ll start with woody plants (trees, shrubs, lianas) that exhibit brachidodromous leaf venation. This is just a fancy word to describe a leaf with a single midrib (primary vein) in which the secondary veins do not touch the leaf margin (edge) but instead curve toward the tip of the leaf and connect to the next secondary vein above. See Manual of Leaf Architecture (2009) by Ellis, Daly, Hickey, Johnson, Mitchell, Wild, and Scott. I thought for sure this fancy word, brachidodromous, would be in my 206-page book Plant Identification Terminology by Harris and Harris, but no. I guess the word is used by people who study plant fossils more than by botanists.
Anyway, here’s the start of my list:
- Osage Orange
- Red Mulberry
- more to come
