I do not want to end the previous identification of the varieties and do not want to simply synonymize them probably prematurely. I have simply attached the two varieties unchanged to Senega verticillata so that we can find a solution later.
The varieties must either be synonymized later if they are not accepted or they must be transferred to the genus Senega at a later date as soon as they have valid descriptions under this genus name.
Have the subgenera and sections been created already? Based on the paper, I'd infer that P. verticillata will be in section Verticillatae
Edit: Saw all the new sections within Senega have already been created
