Summary
editDescriptionAcacia decurrens branchlet 1.jpg |
Acacia decurrens. Waterfall NSW Australia, July 2011. PlantNET describes Acacia decurrens having "branchlets angled with winged ridges which are decurrent with the petioles". I thought that I might be able to illustrate that feature with this photo, but I am not convinced. There is a ridge running along the horizontal branchlet. Does the ridge have wings? It is anvil-shaped in cross-section, so maybe. Trouble is, the petioles hold the leaf up, not down. Does this mean the branchlets are decurrent with the petioles? If so, I find it a funny way to describe what's going on. |
