3. Catharinaea papillosa New Species. 



(Plate XXVII) 



Plants loosely cespitose, dark green, dioicous : stems 

 simple or at the base sparsely branched, towards the base 

 radiculose, erect, about 2 cm. high, chestnut-brown to purple ; 

 lower leaves dark green, short, oblong, above gradually longer, 

 erect-spreading, the upper leaves tufted, erect-spreading to 

 erect, oblong-linear, 3-5 mm. long, 0.7-1.0 mm. wide, margined, 

 above chlorophyll-bearing, obtuse to somewhat acute, towards 

 the apex dorsally serrate-spinulose, in the margin above the 

 middle more or less doubly serrate-spinulose, when moistened 

 slightly undulate, when dry crisped and circinate, lamellate 

 ventrally along the percurrent costa ; lamellae 6-8, mostly 10-14 

 cells high, smooth or minutely and sparsely papillose, above 

 the middle extending over ^-/i the width of the leaf ; leaf- 

 cells on both sides usually slightly minutely papillose, the 

 lower cells hyaline, hexagonal-rectangular, about 10-15 by 

 .030-.045 mm., the median more or less quadrate, the upper 

 cells quadrate-orbicular, chlorophyll-bearing, about .008-.015 

 mm., the lower border cells linear, incrassate, in two to three 

 series, more or less two-layered, towards the apex gradually 

 becoming rectangular, in the teeth triangular and sometimes 

 .125-.140 mm. long; perichsetial leaves similar to the stem- 

 leaves ; the perigonial leaves of the antheridial plants from 

 an ovate-orbicular concave base abruptly linear-acuminate, 

 about 2 mm. wide and 3 mm. long, towards the apex canalicu- 

 late, lamellate marginally and dorsally serrate-spinulose and usual- 

 ly sparsely papillose ; lamellae usually papillose, 4-6, only 3-7 

 cells high, disappearing quickly below the base of the acumen: 

 flowers dioicous or rarely arising from the center of the 

 masculine flower of the preceding year : seta solitary, erect, 

 flexuous, slightly sinistrorse, about 2 cm. long, smooth, sub- 

 lustrous, chestnut-brown; capsule linear-cylindric, 3.5-6 mm. 

 long, 0.5-0.7 mm. in diameter, erect-arcuate, tapering abruptly 

 at the base, smooth, chestnut-brown ; cells of the capsule rec- 

 tangular, their lateral walls much incrassate, in a series of 5 

 or 6 cells under the mouth smaller, quadrate, dark-incrassate; 

 peristome teeth 32, linear-oblong, about 0.3 mm. high, in the 

 median line reddish-orange, towards the sides hyaline, in the 

 margins a little dark and densely although minutely papillose, 

 forming a basal membrane in the lower third; spores smooth, 

 incrassate, orange-pellucid, globose, about .008-.011 mm.; 

 calyptra about 5 mm. long, narrowly cucullate, much shorter 

 than the capsule, towards the apex spinulose-hairy ; operculum 

 hemispheric-conic, shining, dark chestnut-brown, terminating 

 in an oblique linear-subulate rostrum 1.8 mm. long. Known 

 from the following localities :
