This is one of several instances of a disjunct distribution where a taxon is common to the sandstone, the Amazon, and the cordilleran areas of northern South America. Isotypes of both species described by Dr. Kostermans are before me. Any visible difference between them seems to be well within the latitude of variation frequently found in species of lauraceous genera. Examination of the isotypes does not disclose the differences which a comparison of the original descriptions would indicate. There remains the possibility, however, that there has been an error in numbering the sheets. This species, by an odd coincidence, superficially resembles very strongly Ocotea gracilis (Meissner) Mez, but on examination of the flower is immediately placed in E)idlicheria. The leaves of the Ocotea have longer caudate tips than those of the above species. Endlicheria gracilis apparently has no close relatives within the genus.
