[Trinity] Plant identification in Trinity College MS O.2.48 Apuleii Herbarium

[Koen G]

That drawing is a dandelion if I've ever seen one. They grow everywhere around here these days. Like, you look away from your garden for five minutes and before you know it it's full of dandelions. Everything matches, apart from the fact that you don't get a full view of the flower.

The text says that it grows in the mountains - might this be the case in southern Italy? There are apparently some species that only grow in the mountains. 
The common name is weird indeed. It probably doesn't help that these types of plants get a dozen different names in areas where they are common. Just from the English wiki:

Taraxacum officinale has many English common names (of which some are no longer in use), including blowball, lion's-tooth, cankerwort, milk-witch, yellow-gowan, Irish daisy, monks-head, priest's-crown and puff-ball;[25] other common names include, faceclock, pee-a-bed, wet-a-bed,[26] swine's snout,[27] white endive, and wild endive.[28]

Now if you turn conoriel into coroniel there might be a hint of a relation with "corona", though that's probably a bit far-fetched.
