6.4mm | | The leaves clearly shows why this is "whorled" loosestrife. The flowers are on pedicels arising from the axils of the leaves that are in a whorl around the stem. Notice the reddish tint of the top whorl of leaves, indicating a plant that has been receiving significant direct sunlight. | | Click on the photo for a larger image

90mm (135 equiv) Flash: Yes | | The blossoms (buds in this photo) are on long, thin pedicels that arise from the leaf axils. Sometimes the weight of the blossoms will cause them to drop below the leaf whorl, or they may rest on the leaf, or rise above it. The stem of the plant is smooth to moderately hairy. | | Click on the photo for a larger image
