> Just pure, unadulterated pomology

The site is caught in something of a bind as to its name. "Pomiferous" isn't correctly formed; it means "fruit-bearing", because Latin pomum refers to all fruit equally.

The word for an apple is malum. But in an English-speaking context, that will tend to confuse people over similarity to the word for evil, which is... malum [compare "malevolent"]. (In Latin, the word for "apple" has a long A, while the word for "evil" has a short A, but this is not a distinction we can draw in English.)

-logy is a Greek-derived suffix and you'd want a Greek root. For apples, the ancient Greek word appears to be "melon", so your word would be "melology".
