Crotalaria dura subsp dura - Chales Stirton comments

David Styles did a useful summary distinguishing Crotalaria dura ssp dura and C. globifera. See https://www.ispotnature.org/communities/southern-africa/view/observation/486252/crotalaria-dura-subsp-dura

In essence he said quoting Marianne Le Roux:

Crotalaria dura subsp. dura has a prostrate, decumbent to decumbent-erect habit, whereas C. globifera has an erect habit.
Crotalaria dura subsp. dura has a keel petal that is rotund (U shaped) unlike the angled curvature and distally straight and elongate beak of C. globifera (looks like a medieval pointed shoe) (thanks to Marianne le Roux for this, included in an article previously published in PlantLife)
Note also the often brown calyces seen in Crotalaria dura subsp. dura.
