Related species

The combination of subglobular lower pitchers, densely fringed wings (often with clustered filaments) and proportionately long tendrils separate ''N. bellii'' from all other species with the possible exception of the miniature '' N. argentii''. However, the latter species can hardly be confused with ''N. bellii'' as it does not produce a climbing stem, differs markedly in the shape of the lamina, and has a uniquely curved peristome that continues along the lower surface of the lid. ''Nepenthes bellii'' is closely allied to '' N. merrilliana'' and '' N. surigaoensis'' and shares with these species a similar morphology of the pitchers and laminae as well as a reddish colouration of the uppermost leaves. It is not easily confused with them, however, because it is much smaller in all respects, particularly in the size of its pitchers and inflorescence. More generally, ''N. bellii'' appears to fall under B. H. Danser's classical '' Insignes'' group, which also includes '' N. burkei'', '' N. insignis'', '' N. merrilliana'', and '' N. ventricosa'', among others, with '' N. sibuyanensis'', '' N. barcelonae'' and '' N. aenigma'' being recent additions. ''Nepenthes bellii'' was also compared to '' N. micramphora'' in the formal description of the latter, in which the authors noted that the stem, laminae and inflorescence of ''N. micramphora'' match those of ''N. bellii'' "almost exactly".Heinrich, V., S.R.
