MOSSES WITH A HAND-LENS 



lid adheres to it and is raised upon it, as in 

 Fig. 37- 



Co7istricted, used of capsules that become nar 

 rowed under the mouth when dry. (Fig. 32.) 

 Contracted, see constricted. 



Cribose, (peristome teeth) perforated with 

 small apertures. (Fig. 38.) 



Cucullate calyptra, a calyptra that is hood- 

 shaped and split on one side only. (Fig. 33.) 



Cygneous, (seta) curved suddenly downwards 

 like a swan's neck. 



Deopcrculate, applied to a capsule after its lid 

 has fallen off. 

 Dimidiate, split on one side. 



Divisural line, the line down the teeth of a peristome, 



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 perichastial leaves reach but do not overtop it. 



Endostome, see under peristome. 



Endothecium, 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.) 

 Exostome, see under peristome. 



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

 sule, when the perichsetial leaves do not reach so high as its base. 

 Fenestrated, perforated. 

 Geniculate, (seta) suddenly bent, like a knee. 



Gibbous, (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 ox granulated, rough as with 

 minute grains of sand. 

 Gymnostomous, without a peristome. 



Hygroscopic, readily absorbing water and thereby altered in 

 form or direction. Hygrometric is sometimes used with a similar 

 meaning. 



Hypophysis, a swelling of the seta immediately under the 

 capsule. (Fig. 35.)
