This plant has the style-arms of Lopholxna, not of Othonnopsis äs 

 Benthani Ihought. As the same mistake has been made by olher 

 authors, research among species referred to Senecio and Othonna will 

 probably bring other species of this genus lo light. Meanwhile a clavis 

 of the genus as known today will, perhaps. not be ont of place here.
