Flexuose, wavy or bending alternately back and forward. 

 Frondose, bearing fronds or frond-like. 

 Fugacious, falling away very early. 

 Fusiform, spindle-shaped. 



Gametophyte, the sexual stage in the life-history of the moss and resulting from the germi- 

 nation of a spore. Usually begins with a filamentous protonema which eventually 

 gives rise to leafy stems, which finally bear the sexual organs (archegonia and 

 antheridia) and, upon the fertilization of the archegonium, there is produced the 

 other alternating phase, the sporophyte. 



Gemmae, small more or less bud-like bodies capable of reproducing the plant. 



Gemmiparous, producing gemmae. 



Geniculate, bent like a knee. 



Gibhous, swollen on one side. 



Glabrous, with a smooth surface. 



Glaucous, covered or whitened with a bloom. 



Granulose, finely roughened as with grains of sand. 



Gregarious, growing near together or in groups but not forming tufts or mats. 



Gymnostomous, with the mouth of the capsule devoid of peristome. 



Hamate, hooked. 



Heteroicous, with two or more forms of inflorescence in the same cluster. 



Hispid, beset with stiff hairs. 



Hispidulous, minutely hispid. 



Homomallous, (leaves) bent or curved to one side, all in the same direction. 



Hyaline, transparent and colorless like water. 



Hygroscopic, altering form or position with changes in moisture. 



Hypophysis, an enlarged of the seta immediately below the capsule. 



Imbricated, overlapped like the shingles on a roof. 



Immersed, (capsule) concealed within the leaves of the perichaetium. 



Incrassate, thickened, or thick-walled (cells). 



Indehiscent, not splitting open. 



Inflorescence, the clusters of reproductive organs, usually with enclosing bracts. 



Innovation, a young offshoot from the stem. 



Insertion, the point of attachment of the leaf to the stem or branch. 



Involucre, a whorl of leaves or bracts around the flower. 



Jutaceous, worm-like or catkin-like. 



Laciniate, deeply slashed or cut into narrow lobes. 



Lamellae, thin plates, particularly the flat plates on the dorsal surface of many peristome- 



teeth; also on ventral surface of many leaves. 

 Lamina, the leaf-blade. 

 Lanceolate, lance-shaped. 



Lid, the covering of the mouth of the capsule, the operculum. 

 Ligulate, strap>-shaped. 



Linear, long and narrow with parallel sides. 

 Lingulate, tongue-shaped. 

 Lumen, the cavity of a cell. 



Mamillate, tipped with a nipple-shaped projection. 



Margin, (of a leaf) a bordenng band of peculiar shape or color. 



Mitriform, mitre-shaped, or like a peaked cap, symmetric. 



Monoicous, with the antheridia and archegonia on the same plant. 



Mucronate, with the costa percurrent as a short small abrupt tip, tipped with a mucro. 



Muricate, with the surface roughened with short, hard pwints. 



Muticous, not pointed.
