Sesbania bispinosa var. bispinosa

[Stoffel]

We noticed a plant around Satara - especially between the camp entrance and the bridge over the Shitsakana (south of the camp) and also along some areas of the S90. I don't know whether we were unobservant in the past, but this seems to me like some or other invader species. It was normally very easy to see the plains game on the plains south of the camp, but this "invader" is really blocking one's view now. The very thin pods are full of small seeds, making spreading rather easy. Or am I wrong with my assumption of an invader?

If no one can say for sure, I will ask Kruger's alien plant guys.

I also saw them earlier this year but have no idea what they are?

Dear Dalene

The pictures are not that clear but it looks like Sesbania bispinosa var. bispinosa which according to the latest SANBI list has been classified as a naturalised species.

I will ask for more pictures from colleagues who will be travelling around Satara area.

Thank you

It is an annual shrub which can grow to seven metres in height but usually only reaches one to two metres. It sends out fibrous, pithy stems with long leaves and bears purple-spotted yellow flowers. It produces pods which contain light brown beans.[1]
