Slightly or somewhat rough or roughened in texture or surface.
From Latin 'asper' (rough) + diminutive suffix '-ulus' + English adjective suffix '-ous'. This combines to mean 'somewhat or slightly rough in quality'.
Asperulous describes that feeling when something is rougher than smooth but not really bumpy—like certain leaves or seeds under a microscope, it's a specific texture that scientists and botanists use to distinguish plant features.
