Add genus to subfamily lookup

[wcornwell]

Would be extra-useful for Asteraceae and Fabaceae and other big families.

But not sure what the right source is to get this information for the whole set of global genera.

Thanks Will. I think one possibility could be NCBI taxonomy databases, which include lower ranks (e.g. tribes, subfamilies). But not completely sure if the whole set of genera of those big families are represented at NCBI.
