i guess, i was just over-thinking it - the obvious 'pick me pink' search just totally eluded me. i can google search a needle in a stack usually, so that's why i got flummoxed a bit ;).
i pounced on a search bar instead of actually looking at other things - and missed specialty databases staring me in a face :).
but still, if we take 'musa' as example - why do i have a different number of entries on the first screen vs 'all plants in the genus' list?
i see it's picking up totally unrelated entries like 'musaefolia' even if i put "musa " for exact search.
and also Hemerocallis 'Vermusae' - which really it shouldn't!
i can see now that genus-list + pick-cultivar-letter would be the fastest and most accurate search.
thanks for all clarifications.
