Aulomyrcia amshoffiana Steyerm., Fieldiana Bot. 28: 1003. 1957
A distinctive endemic montane species, readily recognized by the whitish pubescence of the slender inflorescneces, and by the coriaceous leaves with impressed mid-vein: the leaves in drying become rusy -red beneath. For description see Amshoff (Bull. Torrey Club 75: 532) or Steyermark (Fieldiana Bot. 28: 1003, 1004. 1957).
The original specimens of Myrcia albido-tomentosa came from British Guiana, and

that not a particularly variable one, is involved. A superficially similar species, readily
distinguished by the characters used in the key above, is M . ptariensis.
This species is one of these on the borderline between Myrcia and Marlierea,
resembling the latter in its 4-merous calyx, the lobes of which are sometimes partly
