MOSSES WITH A HAND-LENS 



189 



In some species of Fissidens the border is of a different color, 

 but with little difference in cell structure. 



Bracts, a term applied to the leaves surrounding the repro- 

 ductive organs. Those surrounding the antheridia are called per- 

 igonial bracts or leaves, and those surrounding the archegonia 

 and base of seta are called perichsetlal. 

 Brood bodies. See propagula. 



Bulbil, a minute bulb or bulb-shaped body, usually 

 produced for asexual reproduction. 



Caespitosc, forming matted tufts or cushions ; e. g., 

 Leucobryum. 



Calyptra, the thin veil or hood covering the mouth 

 of the capsule. (Figs. 9 and 22.) 



In the Hepatics the capsule breaks through the FlG ' 9 " 

 top of the calyptra, leaving it at the base of the seta instead of 

 on top of the capsule. (See Marchantia.) 

 Camp emulate, bell-shaped. 



Canaliculate, channeled. Applied to leaves with margins in- 

 curved, so as to give them a channel-like form ; e. g., the upper 

 part of the leaves of Dicranuin fuscescens. A more complete in- 

 rolling until the margins meet would make the leaf tubulose. 

 Canescent, rather hoary. 

 Capitulum, a rounded head. 



Capsule, the enlarged distal end of the sporophyte; it con- 

 tains the spores, and is some- 

 times known as the sporan- 

 gium. (Figs. 6, 8, 10 and 17.) 

 Carinate, keeled like a boat ; 

 e. g., segments of inner peris- 

 tome in Fig. 27. 



Ccrnuous (capsule), droop- 

 ing or nodding, somewhat in- 

 clined as opposed to erect. (Fig. 10.) fc . 

 Chlorophyll, the green coloring matter in plants. 

 Cilia, hair-like threads of the endostome, alter- 

 nating with the segments. (Fig. n c, and 27 d.) 



Circinate, curved into a circle, resembling 

 Fig. 2, but still more incurved, so that the apex 

 is nearly or quite bent around to the leaf base; 

 e. g., leaves of Hypnu-in nncinatnin. FIG. n.
