- n. See two-storied, 2.
Sorry, no etymologies found.
Even a very thick stand of young hemlock is unlikely to produce much if the overwood has been very dense, for much of it may be so old and stunted by shade that sudden advent of strong light will result merely in distorted worthless branch growth or in killing it outright.
The understories of varying ages are as dense as their light requirements and the density of the overwood permit.
