Matthew Jebb
In their 1997 monograph on the genus "Nepenthes", Matthew Jebb and Martin Cheek designated the male specimen deposited at the Paris herbarium as the lectotype of "N. thorelii". The authors noted that there are "problems with the delimitation" of "N. thorelii" and the related taxa "N. anamensis" and "N. smilesii" (which are now considered conspecific).
