specio

This is a false friend, and it is the classic one. Specio means species in the strict biological sense and nothing else: a rank in the classification of living things, below the genus, the level at which a wolf and a dog are argued about. If you want to say kind, sort or type in any ordinary sentence, the word is speco.

So kia speco de kafo? is what kind of coffee, and kia specio de kafo? asks which botanical species the plant belonged to. Ĉiaspeca means of all kinds; ĉiaspecia is not a word anybody wants. English speakers import the error because English species and kind feel like registers of one idea rather than two words, and because specio looks so much more like species that it seems the obvious choice. It is the wrong one nineteen times in twenty. More of this family in the chapter's article on false friends.

The rest of the biological vocabulary is regular: genro is the genus, familio the family, speciaro a set of species, and subspecio a subspecies. And note that speciala (special) belongs with speco in feel but with neither in grammar - it is a third root again, borrowed whole.
