Discussion

  • Taxonomic notes:-Henderson (1995) recognized this taxon as Desmoncus mitis Martius var. mitis, and included D. pumilus Trail and D. setosus var. mitescens Drude as synonyms. Desmoncus pumilus Trail is here treated as a distinct species, and D. setosus var. mitescens Drude as an Excluded Name. The type of D. mitis was given by Henderson (1995) as Martius s. n., and this specimen is extant at M and is here lectotypified. However, there is some doubt concerning the type locality. It is given on the label as "Provinciae flum. Nigri" and in Martius (1823-1837) as "fluvii Solimoës", presumably in Brazil (Amazonas). All the specimens cited here come from further west than the most westward point of Martius? journey in modern-day Colombia, with the exception of Aguirre-Galviz 1152 from Colombia (Amazonas).
