Martin Cheek
In 1997, Matthew Jebb and Martin Cheek published their monograph "A skeletal revision of "Nepenthes" (Nepenthaceae)", in which they referred to "N. dubia" plant material from Mount Talang ("Kurata s.n." SING). Charles Clarke later identified "Kurata s.n." as representing "N. inermis" × "N. talangensis".
