"Just google image it." Of course, how else can we explain to our assistant what Lemon Grass is? "I know it! We call it tea leaf." Liberian's have a very straightforward way of naming things; but I didn't think you could get more descriptive than "Lemon Grass." You can though, if you name it for its use.
That's also how you can return to the house, ten minutes after you left, bearing an uprooted tuft of lemongrass: plead for medicine to combat your malaria. I had no idea that our shy and scrupulous assistant had so much guile. He was beaming with pride as he reported telling his cousin something like, "I'm feeling too bad. The malaria is troubling me. I need this tea leaf fast."
The tea leaf is now replanted in a small hand-made clay pot. If our assistant actually does contract Malaria (for the umpteenth time this calendar year), we'll make sure that he takes something with a better track record than lemongrass tea.
