The Pennywort is one of those plants with a creeping stem, which lies along the surface of the ground. The stem is a delicate, pale pink, and wherever a bunch of flowers and leaves rises, you find a tuft of white, hair-like roots growing down into the mud. 3. INTERMEDIATE WINTERGREEN It is a great delight to discover this dainty plant. It is not very common, but in summer and autumn you find it blooming on heaths in many parts of the country. The Wintergreen flowers are not unlike Lily-of-the-Valley. They are delicate, creamy white bells, which hang from short drooping stalks near the top of a slender stem. These bells have five ivory petals slightly tinged with pink, which form a dainty fairy cup. Within the cup there is a ring of ten stamens with heavy yellow-heads, clustered round the tip of the green seed-vessel. This green tip rises in the centre, like a slender pillar, a good way above the stamens. Behind the ivory cup is a green star, with five points. These points are the sepals. Notice that wherever a flower-stalk joins the main stem a tiny pointed green leaf appears. The soft juicy stem is twisted near the top and is four-sided. It grows straight from the root. The dark glossy leaves of the Wintergreen are spoon-shaped, with wavy edges. They spring from the ground with very short stalks, and they remain on the plant all winter. PLATE XXV: 1. GRASS OF PARNASSUS. 2. COMMON BLADDER CAMPION. 3. SEA CAMPION. 1. GRASS OF PARNASSUS This slender plant grows in bogs and damp places all over Britain and blooms in autumn. It has large white flowers, which grow singly at the end of tall green stalks. These stalks are square and slightly twisted. Each flower has five creamy-white petals, covered with delicate veins. Inside this ring of petals, lying at the bottom, are five curious scales, like tiny hands. The hands have each ten fingers, tipped with yellow dots, so you may count fifty dots altogether. On the scales are glands which hold honey. This, you may be sure, the bees very soon find out. In the centre of the flower is a round pale green seed-vessel, and in between the scales with the tiny yellow dots lie five fat stamens with heavy yellow-heads. The Grass of Parnassus has also five green sepals, whose tips you can see appearing in between each of the five white petals, as you look down into the flower. Most of the green leaves of this plant grow from the root. They are oval, with smooth edges, and each leaf has a stalk of its own. But often you will find a single leaf clasping the flower-stalk half way up its stem, and this leaf has no stalk of its own. 2. COMMON BLADDER CAMPION The Common Bladder Campion is to be found all summer by the edge of fields and pastures. It is a tall, slender plant, with white flowers which grow each on a thin short stalk, two or three close together at the end of a smooth stem.
