Veins pinnate and free.
Spore cases lateral; the base of the pedicels concrete, and
producing an elevated thickened receptacle.
The hab it of the genus exceedingly beautiful, and very
distinct.
Most authorities consider th a t th e re are two species, one
from Germany and the other a native of N o rth America, yet
th ey are scarcely distinguishable; probably the geographical
separation of the two plants has had more to do with placing
them as distinct species th an any specific difference in the plants
themselves.
