Characterized by appendages; having a tendency to append or attach things; somewhat unusual formation suggesting abundance of appendages.
From Latin appendix + -ious (adjective suffix meaning having the quality of). The -ious ending suggests inherent quality, similar to 'capricious' or 'judicious,' though this word is extremely rare.
The suffix -ious usually means 'full of' (precious, capricious, delicious), so 'appendicious' would mean 'full of appendages'—but it's so rare that few dictionaries record it. English created it logically but never actually used it!
