Caelum shook her head as they walked. "I didn't hear... I though it was just some sort of punishment hike. Do they usually give a project or task?" 

Caelum found this whole concept and version of 'detention' to be very strange. In muggle schools they punished you with boredom, forcing you to sit in a room for a certain amount of time. In other types of educational institutions, such as in the finishing, boarding, or military schools they might punish the students with push ups or carrying buckets of water or other difficult physical tasks. Was a wizards punishment a difficult [i]magical [/i]task? 

Cassandra spoke up. 

"Alright, I know you haven't had a Herbology class yet... What we are doing is looking for [i]Silver Asphodel[/i]. It's a flower, kind of like a Lilly. You have probably seen regular 'ol Asphodel that grows around the castle, it's white and bigger than what we are looking for now. The silver kind only seems to grow in the dark forest and bloom at night. You can't miss it. Tiny silver Lilly, the flute has five or six points, the leaves and stems are a little bit fuzzy like Heather or Billy-Bumblers-Ear. [i]Don't eat it[/i]." She passed around soft velvety black pouches to each student. "Be careful not to crush them but try to get the whole thing in tact, including the root and all, in here. The roots don't go deep you won't need much more than your fingers to work it out. If it doesn't come out easy, you might have the wrong plant. Don't pick the wrong plant."

She didn't say [i]why[/i] not to pick the wrong plant, speaking as it if were obvious, the way she said [i]don't eat it[/i].
