Remarks

The epithet honors Julian A. Steyermark (1909-1988), an extremely busy botanist who collected over 130,600 plants in twenty-six countries and described 2,392 different plant taxa, including Juniperus standleyi. He collected the type specimen of this species, as well as of Podocarpus buchholzii, P. magnifolius, and P. tepuiensis.
