Also, in zoology, of a surface, appearing as if dusty or covered with fine dew -- as plums often are. Not sure how that dusty sense creeps in, given the root is very firmly dewy: from Latin rōrulentus, from ros, dew. Regardless, this is a much quieter word than it sounds -- I first thought it might mean bright red, or maybe that lions could be described by it.
The rorulent spiderwebs glittered in the morning sunlight.
