The key to Swainsona in PlantNet starts with the hairs - whether they attach at one end or in the middle of the hair. To get round this, I devised a way to tell the four species of Swainsona in the ACT apart using leaflet width, number of leaflets per leaf, hairiness of the stem, and the relative length of the calyx body (cupping the flower) and the calyx teeth. Using this, I can say that your plant is either Swainsona sericea or Swainsona behriana. Not being able to see the calyx that is as far as I can go.
