Taken on 2 nearby plants. The flowers have different colours & detail shape. The seed pods look also a slight difference. Are these 2 the same Arugula, or different culivars ?
The second one looks more like the radish I posted one year for ID, Raphanus sativus. Definitely Brassicaceae. Radish? You're so stingy with your photos! How about leaves, and the shape of the whole plant? Your detail photos are incredibly beautiful and helpful, but we often also need some garden-variety snapshots of what the whole thing looks like if you want IDs. Maybe I'm trying to train you to look at those things - I think the leaves of these two plants would be have been different.
Ha ha, reason is that most of the leaves were gone, and what were left were not in good shape, and sparsely distributed. It's quite difficult to include everything in a photo, else every part would be widely separated, and what was more, I had to fight with the wind which threw my focus off, less than 1 pic was retained out of 20 shots. Right now I am suffering from allergy with running nose and smarting eyes, even after taking non drowsy Reactine, yet still suffered from its side effect, drowsiness !
You're allowed 20 photos in a posting. You can take a separate photo for every two inches. Well, maybe that's overkill. Your comments about your focus being thrown off are not convincing. :) But I do know about wind. So my sore throat since the beginning of April could be an allergy?
Any other symptom other than sore throat ? That usually don't linger on for so long ! My allergy is postponed this year. Usually it starts around mid June. Now it started mid July. Possibly the colder weather (the coldest summer I had in 29 years in Canada, as well as my whole life), postponed the pollen dispersion ?
I went a whole day yesterday without wearing my down jacket. Summer might be on the way. I'm sorry about your allergies.
