紫蘇屬

紫 = 此 + 糸 : Zorro (z) needs some more special effects dust. To make it, he crushes a few amethysts (紫) in the space station (Ø3) by stomping on them with his boots (此). He then crafts a few bags out of a silken scarf (糸) to store the dust in.

苏 = 办 + 艹 : Susan Saint Bernard (su) set up a new business (办) in front of the space station (Ø1). She is growing wild red basil (苏) on sheets of artificial lawn (艹) which provide just the right nutrients. Because it will take the basil really long to grow, Susan Saint Bernard just takes a nap. When the basil is big enough she will wake up (苏) and sell it.

属 = 尸 + 禹 : 暴龙属 is the genus Tyrannosaurus, and I'll use a T-Rex as mnemonic symbol.

The great Yu (禹) built a dyke to prevent Sheldon Shrimp (shu) from entering his side of the space station (Ø3), but then a T-Rex (属) ghost (尸) starts to haunt him until he tears down his dyke.
