closely imbricate, ovate or ovate- oblong, 1/2—3/4", subcordate, shortly and 
obliquely acuminate, serrato-dentate on the upper margin, deepest near 
the base, entire below or denticulate near the apex. Intermediate leaves '/2 
or 1/3 as long, ovate to obovate, erect and appressed in 2 parallel sdisien 
keeled and mucronate, denticulate on both edges. Spikes very numerous 
one to each branchlet, sharply tetragonous, slender and long, 6—20"", 
often curved. Bracts closely imbricate, keeled and mucronate, i 
denticulate. Macrosporangia little larger than the microsporangia, 2- valved, 
each with 3 or 4 smooth globules. Microsporangia confined to the apex,
