Pinus caribaea tree /P. caribaea foliage leaf / female cone / male cone   Female cone of Pinus Male cone of Pinus Lemon Grass (Cymbopogon citrus) Lemon Grass is a tall tropical grass. The fresh stalks and leaves have a clean lemon like odour because they contain an essential oil, which is also present in lemon peel. Lemon grass is a long thick grass with leaves at the top and a solid portion several inches long at the root end. It is well known a mild insect repellent (citronella) and the essential oil is used in perfumery.  Lemon Grass Queen Sago (Cycas circinalis) GYMNOSPERM |
