accrescent, concave, orbiculate, broadly ovate or ovate, emarginate, 

 rarely entire, sinus shallow, /, to J deep, obtuse or rarely acute, 

 segments obtuse, rarely acute ; texture somewhat thick, cells 

 moderately large, roundish subquadrate, lumen with oil corpuscles

 with one, two, or three irregular segments on one or both sides. 

 Involucre oval or clavate, composed of two large bracts with 

 bracteole (irregularly cuneate) behind, which is overlapped by the 

 bracts, connate with them at the base ; bracts 2 to 3 pairs, larger 

 than the leaves, subrotund, emarginate, margin irregular, crisped, 

 ventricose at the base. Perianth immersed, composed of elongate, 

 hyaline cells, mouth irregular, contorted, lower half adnate to the 

 innermost bracts. Calyptra delicate, cells irregular in shape, walls 

 very thin ; at its base are 8-10 barren pistillidia. Capsule brown. 

 Spores smooth, light brown. Elaters darker brown than the 

 spores, bi-trispiral. Antheridia roundish-oval, stipitate, usually 

 two in each bract below the perianth. 

 Fruits March, April.
