Right, no one is saying you should always just blindly accept the CV or that the CV is never wrong.
Interestingly, with the observation in question, even if I turn off ‘seen nearby’ and force it to only suggest things in family fabaceae, it still only ranks ‘Orchid Tree’ as the fifth most similar looking Legume. It thinks the most similar looking Legume is redbud, which seems like a plausible most similar legume. I wonder why Seek ranked it so differently.
