 through which they split. (The zigzag line down the middle of 

 the teeth and the line down the middle of the segments in Fig. 43. ) 



Emergent, or emersed, half uncovered ; of the capsule, when 

 the perichtetial leaves reach but do not overtop it. 



Efidostome, see peristome. 



Etidothecium, the inner layers of cells of the capsule. 



Epiphragm, a membrane covering the mouth of the deoper- 

 culate capsule ; in the Polytrichums and their allies it consists of 

 the dilated top of the columella. (Fig 35, a.) 



E.xostome, see peristome. 



Exserted, elevated above the surrounding parts; of the cap- 

 sule, when the perichtL-tial leaves do not reach so high as its base.

Cenictilate (of the seta), suddenly bent, like a knee. 



Gibbous (of the capsule), more tumid or 

 swollen on one side than on the other. 



(Fig- 39 ) 



Glaucous, originally applied to plants 

 covered with a bluish white bloom, but 

 now applied to mosses that have that color. 

 Granulose, or granulated, rough as with 

 minute grains of sand. 

 Gyninostomous, without a peristome. 



Hygroscopic, readily absorbing water and thereby altered in 

 form or direction. Hygrometric is sometimes used with a similar 

 meaning. 



HypopJiysis, a swelling of the seta immediately under the 

 capsule. (Fig. 35.) 



Immersed, covered up; of the capsule when the perichastial 

 leaves project beyond it. 



Leptodermous, thin coated; applied to capsules when soft 

 and pliable. 



Lid,='^percultcm, which see. 



Mamillate, or mammillar (of the 

 lid of the capsule), convex with a

 40 and 41.) 



Mitriform (of the calyptra), cleft 

 on two or more sides, and symmet-
