旧大陆的猪笼草
Habitat photographs of a taxon matching the description of "N. abgracilis" appeared in a 2008 issue of the German-language periodical, "Das Taublatt", and in the second volume of Stewart McPherson's 2009 work, "Pitcher Plants of the Old World". In both it was identified as a variant of "N. alata" (at the time considered a highly variable and widespread species, but which has since been split into a number of daughter taxa).
