Alright! The flower is plucked from the ground, and she'll notice that as soon as she plucks it, it squirms and thrashes violently for a while, and then goes still. That'll make it much easier to dissect.

Olivia will notice a few things upon observation: The first is that the plant appears to be a tropical variety (there are multiple tropical-looking plants among the pack, but she has specifically picked up something akin to Epiphyllum Argus), and the second is that, for some reason, the plants have teeth. If she were to cut open the center of the plant, she would see that it has pharyngeal teeth as well. This particular one is, of course, filled with a bit of tasty blood. Yum yum. :)

From there, what would be considered plant-esophagus travels down the stem and into a pool of... well, it's difficult to tell what that fluid is at the bottom of the stem where it was torn away, but Olivia might think it's a digestive fluid akin to what is in pitcher plants. There's something of a "pocket" at the thicker base of the stem that's leaking out the bottom at the breaking point. Otherwise, the plant's physiology appears normal — leaves are where they should be, the stalk is firm, the plant probably does photosynthesis but she'd need a microscope to confirm for sure.

Is there anything else she'd like to look into physiology-wise?
