Resembling or consisting of small drops; having the quality of being covered with or made up of tiny droplets.
From 'guttule' or 'guttula' + the adjectival suffix '-ous' (full of, characterized by). This creates an adjective meaning full of or characterized by small drops.
The suffix '-ulous' (as in 'credulous,' 'tubulous') is relatively rare in English, making 'guttulous' sound more like a specimen from an old botanical textbook than everyday speech.
