1. Most pinnz distinctly stalked, scarcely incised halfway down to the 
costa; segments 6—8 mm broad; lower 2—6 veins on the same side 
of the costule united along a carlilagineous membrane or keel below 
the sinus, thus forming 2—4 areoles on each side of the costule. Long, 
pluricellular hairs none. Lamina upwards suddenly narrowed into a 
hastate, terminal pinna.
