MOSSES WITH A HAND-LENS IQI 



Cymbiform, boat-shaped (used by Dixon as a 

 synonym of cucullate) ; e. g., leaves of Sphagnum 

 cymbifolium. (The whole leaf in Fig. 14.) 



Deoperculate, applied to a capsule after its lid 

 has fallen off. 



Dichotomous, branching by forking repeatedly 

 into two branches. 



Dimidiate, split on one side. 



_ Dioicous or dioecious, having the male and 



Fie. 14. ' ° 



female organs on separate plants. 

 Distichous (of leaves), in two opposite rows on the stem. 

 Dorsal, belonging to or on the back; i. e., the face of a leaf 

 remote from the stem. 



Bcostate, lacking a costa. 



Bmarginate, having a small notch at the end of apex as in the 

 figure of the leaves of Lophocolea heterophylla. 



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

 the perichstial leaves reach but do not overtop it. 

 Bndostome. See under peristome. 



Bpiphragm, a membrane covering the mouth of the deoper- ■ 

 culate capsule ; in Polytrichum and its allies it consists of the 

 dilated top of the columella. (Fig. 10, a.) 



Brecto-patent, midway between erect and patent. 

 Bxcurrent costa, a costa running out beyond the 

 lamina of a leaf. (Fig. 15.) 



Bxostome. See under peristome. 

 Bxserted, elevated above the surrounding parts ; 

 of the capsule, when the perichaetial leaves do not reach 

 Fig. 15. so high as its base. 



Falcate, curved like a sickle. (Fig. 2.) 

 Fascicle, a bunch or cluster of leaves or branches. 

 Fasciculate, arranged in bunches.

 Flowers, often applied to the reproductive organs. 

 Fruit, often applied to the sporophyte.
