The authorship of this combination is usually credited to Wight 

 and Arnott but although they certainly state in the Prodromus that 

 Wallich's plant was a Mezoneuron they did not make the combina- 

 tion. The species is very poorly represented in Herb. Kew and it 

 is not without some hesitation that Kerr's plant is referred to it.
