On onelook, this word only appears in one general dictionary and one botanical dictionary.

The general dictionary (InfoPlease) says it means hirtellous and that hirtellous means "minutely hirsute. Also,hirsutulous." I find "minutely" somewhat vague. Is that small hairs, a small patch of hairs, sparse hairs, ...

I liked the botanical dictionary's "slightly hirsute" better - until I found that they define hirsute as "Pubescent with rather coarse or stiff hairs." (^_^)
