upright, lateral. Capsules egg-shaped. Lid conical, beak short. Mouth 
fringed. Veil upright, covering the young capside. Involucrum very 
short. Weis. When growing out of the water, or where it is often 
exposed to the air, the leaves are shorter and blunter, surrounding the 
stem, but when always immersed in water they are longer, more pointed, 
and wing the stems. Dill.
