MEMOIRS OF THE NEW YORK IIOTAXK'AL GARDEN 



[vol. 11 



1. Temnoma pilosum (Evans) Schuster. Bryologist 62: 240. 1959 (1960). 



Blepharostoma pilosum Evans, Bull. Torrey Club 25: 418. pi. 345. 1898. 

 Blepharostoma pinnatisetum Stephani, Spec. Hep. 3: 639. 1909. 

 Temnoma pinnatisetum (Stephani) Schuster, Bryologist 62: 240. 1959. 



Plants julaceous, appearing to be composed of long, intricately interwoven 

 capillaceous cilia, erect, tending to be radially symmetric, brownish-green, in 

 deep tufts or cushions ; stems slender, 1-A cm long, with leaves to 0.2 mm wide, 

 sparingly pinnate, the branches lateral, of the Frullania type, the half-leaf with 

 only two major segments, at the dorsal base of the branch ; stem in transverse 

 section with the cells of the unistratose cortical layer scarcely smaller than those 

 of the medulla. Rhizoids scarce, from the lamina of the underleaves. Line of 

 leaf insertion transverse. Leaves widely spreading, tending to be decurved in 

 the outer part, broadly orbicular-quadrate in outline, to 0.85 mm long and wide, 

 quadrifid to four-fifths of their length, or six-parted through the development 

 of a large basal tooth on the outer segment on either side ; segments four to 

 seven cells wide at the base, lanceolate, with five to eight pairs of opposite, long, 

 divaricate cilia, tapering to a uniseriate tip of five to eight cells, the cells 40-54 

 (72) X 18 /x, the tip cell shorter; lamina mostly four cells high, the cells mostly 

 36-42 X 16 p., the cuticle faintly striolate. Underleaves like the leaves. Female 

 inflorescence terminal on the stem, without innovations, the bracts and bracteoles 

 in a few series, like the leaves, the inner series larger. Perianth long, cylindric, 

 with three rounded keels above, the mouth broad, spinose to short-ciliate. Male 

 inflorescence and sporophyte not seen. Fig. 1, a-j. 



Habitat : On wet sandy soil. 



PATAGONIA— TIEBEA DEL FUEGO: Villarina Bay, J. B. Hatcher (type Y; isotype 

 NY); Rio Aysen, Dusen 515, type of B. pinnatisetum (G), Dusen 312 (9) (G-1795, NY), 

 Dusen £90 (G-1792) ; s.l., Nordenslcjold (G) ; Chiloe, Halle (G-1793). 



There are additional reports of the species in this area by Arnell (1955), Stephani (1911), 

 and Herzog & Schwabe (1939). 



2. Temnoma chilense Fulford, sp. now 



Similis T. piloso sed cellulis laminae ciliisque longioribus ; laminae cellulis 

 40-54 p., ciliis plus quam 72 p. 



Plants julaceous, large, appearing to be composed of long, capillaceous cilia, 

 ascending to erect, tending to be radially symmetric, brownish-green, in deep 

 tufts or cushions; stems 4—6 em long, the leaves 2-2.5 mm wide, sparingly pin- 

 nate ; stems in transverse section with cells of the unistratose cortical layer 

 scarcely smaller than those of the medulla. Line of leaf insertion transverse. 

 Leaves widely spreading, at a right angle to the stem, the outer part tending to 

 be decurved, broadly orbicular, 1 mm long, 2 mm wide, quadrifid to four-fifths 

 or more and with a shorter segment on either side of the base ; segments lanceo- 

 late, branched and ciliate with opposite pairs, the cilia spreading, five to eight 

 or more cells long, the cells mostly more than 72 p. long, the tip cell 54-72 p ; 

 cell of the lamina mostly 40-54 X 22 p. thin-walled, the cuticle striolate. Under- 

 leaves like the leaves. Male and female inflorescences and sporophyte not seen. 

 Fig. 2, a-c. 



Habitat : On moist shaded sandy bank near a spring. 



PATAGONIA— TIERRA DEL FUEGO: Puerto Varis, R. Hatcher # Fulford (type Hb. 

 Fulford, isotype Hb. Hatcher). 



The species is very similar to T. pilosum except for the larger size, and the 

 longer cells of the lamina and the cilia of the leaves and underleaves.
