 obovate, squarrose, 2 mm. ; margin sub-dentate, nerve 

 slender, vanishing above the middle. Seta short, stout, 2-3

Fam. 10— FUNAIilACEAE. 



Small or medium size, soft, in tufts, or dispersed, erect, 

 simple or with few branches. Leaves few, ovate-lanceolate, 

 with a thin nerve, smooth; cells large, hexagonal to rhom- 

 boid. Capsule spherical, oval or pyriform, erect or cernu- 

 ous on a long seta ; lid short, convex ; calyptra with a long 

 beak and inflated base, cleft on one side or many lobecl ; 

 j^eristome of 16 lanceolate teeth usually twisted or some- 

 times short and straight or absent; endostomc when pre- 

 sent of 16 short lanceolate teeth. 



A well-defined group with laxly-constructed leaves. The- 

 capsule larger than tJie barren base. The peristome when 

 perfect is double, but the endostome is never well 

 developed; the exostome in the most advanced forms has 

 incurving teeth which are attached to a cribiform disk. 

 GiGASPERMDM. Creeping, witli sessile capsules.
