Mikumo does mentally catalog the herb before he puts it away - no harm in knowing if something's edible later on. If it's something he's prone to doing, she supposes it makes sense to carry that knowledge on to here.

"It would have been rather difficult to familiarise myself with local flora where I worked in my world, since it was across multiple planets, but I might take a look into it here, now that you've gotten me thinking about it," she admits. It's not necessarily something that immediately came to mind, because usually her undercover missions were either urban or short enough that rations could cover it. Here, though, getting stranded in the jungle is a real possibility, so knowing enough to get by if that situation arises would be useful.
