OPHIOGLOSSIACEiE. (Adder’s Tongue Family.) 
Botrychium ternatum, Swartz. Moonwort. Frond with an 
anterior fertile and a posterior sterile segment; the for- 
mer erect, 2-4 pinnate, the contracted divisions bearing a 
double row of sessile, naked sporangia; these are distinct, 
rather coriaceous, not reticulated, globular, without a ring, 
and open transversely into two valves. Plant fleshy, 4-16' 
high, sparsely hairy; sterile segment long-petioled born 
near the base of the plant, broadly triangular, ternate and 
variously decompound, with stalked divisions ovate-lance-

leaves. Spore-cases in the axils of the upper leaves forming 
a spike. Stems extensively creeping, often subterranean, the 
erect or ascending branches several times forked above ; 
bushy branchlets crowded, flattened, fan-like and spreading, 
all clothed with minute imbricated-appressed awl-shaped
