awl-shaped, serrate ; nerve broad, excurrent; capsule inclined, ven-

shaped, rather pendulous. — On old walls, and dry or humid ground, 
very common. Dioecious: perigonial leaves terminal, spreading.

entire, mucronate by the excurrent nerve; capsule oblong-pear-shaped, 
pendulous. — Mount Marcy, N. New York. — Dioecious: foliage deep 
shining purple.
