Just to be clear: correlative clauses are not indirect questions. Quot
can be used both as an interrogative and as a relative adverb, but when correlated with tot
it is always relative.
In Catullus 49 quot
is also relative, even though there is no correlative demonstrative present. The missing tot
means that quot
is indefinite. Translate: "O most learned of the descendants of Romulus, as many [of them] as there are, were, or will be in years to come, Marcus Tullius, to you...[etc.]"
