Hi Dave! There are a few options depending on what exactly you’re looking for:
You can check out your Year in Review, which shows a bunch of different summaries: https://www.inaturalist.org/stats/2019/d_coulter
Or use the Explore page filters to sort by your username, plants, and 2019: https://www.inaturalist.org/observations?order=asc&order_by=observed_on&place_id=any&subview=grid&taxon_id=47126&user_id=d_coulter&verifiable=any&year=2019, which can be sorted by date observed=ascending to show earliest to latest observations
Or check out the observations/taxa option, which requires editing the URL directly, but will sort your observations by family and genus: https://www.inaturalist.org/observations/taxa?verifiable=any&user_id=d_coulter&year=2019&taxon_id=47126
More searching tips can be found here. You can also always export your observations (to CSV) and make the exact type of summary you’re looking for - use the Explore page filters to narrow down your query and then click Download in the bottom right of the filters:
