MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[VOL. 11 



of the base of the lamina; margins with very numerous, long, spreading cilia, 

 or the cilia shorter, two to four cells long, in a few opposite pairs on the segments 

 and a few on the margins of the lamina, or entire ; cuticle striolate. Underleaves 

 like the leaves or slightly smaller. Plants dioicous. Male inflorescence terminal 

 but becoming intercalary on the stem or branch, the bracts and braeteoles in 

 four to ten series, a little larger than the leaves and underleaves, with more 

 cilia ; antheridia large, one or two in the axils of the bracts. Female inflorescence 

 terminal on the stem or a long branch, without or with one or two subfloral 

 innovations, the bracts and braeteoles similar and like the leaves and under- 

 leaves, with more cilia on the margins (in species with few or no cilia on the 

 leaves, the margins of the bracts and braeteoles with numerous short cilia, the 

 segments always with numerous pairs), the inner series the largest; archegonia 

 ten to fifteen, flask-shaped with a narrow neck. Perianth long, cylindric, with 

 three rounded keels above, without superficial paraphyllia, the mouth scarcely 

 contracted, spinose to long-ciliate. Sporophyte seta in transverse section of a 

 large number of cells, the outer layer of 18-20 large cells surrounding the 

 numerous similar or smaller cells of the of the medulla ; capsule ovoid-cylindric, 

 reddish-brown, the wall of four to six layers of cells, the outermost layer of 

 very large, hyaline cells, the inner layers of smaller cells with the characteristic 

 brown, rod- or band-shaped thickenings ; elaters reddish-brown, with two or three 

 spirals, the ends blunt-tapering; spores reddish-brown. 



Type species: Jtingermannia pidchella "W. J. Hooker, Musci Exot. pi. 94.

Key to the Species 



1. Leaves and underleaves appearing to be almost completely made up of long, intri- 

 cately interwoven cilia, the cilia occurring singly, or in opposite pairs along the 

 margins of the segments and on the margin of the lamina. 

 2. Cells of the cilia mostly 40-54 (72) /t long, the tip cells mostly 36 p. long. 



1. T. pilosum. 



2. Cells of the cilia mostly more than 72 ii, the tip cells 54-72 /t, mostly 72 /i long. 



2. T. chilense. 



1. Leaves and underleaves with much of the lamina evident, divided to one-half or 

 more of their length; margins of the segment entire or with a few single or oppo- 

 site pairs of short, spinose cilia; perianth 3-keeled above, the mouth broad, spinose 

 to ciliate. 



2. Leaves quadrifid, the margins without teeth, the segments uniseriate from a 



2-celled base, the cuticle very coarsely striate. 5. T. pungens. 



2. Leaves quadrifid, with a conspicuous accessory, narrowly triangular, spreading to 

 decurved, long tooth at the base on both sides of the lamina. 

 3. Segments mostly two to four cells broad at the base, to twelve cells long, the 

 margins with one to three opposite pairs of spinose cilia; superficial spines 

 of one to three cells on the ventral side of the lamina; perianth mouth short- 

 spinose. 3. T. quadripartitum. 



3. Segments to six cells broad at the base, to 20 cells long, the margins entire or 

 with occasional long cilia or teeth; lamina with several long teeth or cilia on 

 both sides. 4. T. subintegrum.
