Symphyogyna undulata Colenso 



Colcnso MS; Stephani, Sp. Hep., p. 340, 1900. 



Hdbiiat. — Pipiriki, North Island, New Zealand; coll. W. A. 

 Setchell, May 27, 1904, no. 10. 



Observations. — Specimens young and imperfect. Costa broad, 12 

 dark colored cells thick ; fronds undulate, furcate ; -wings composed of 

 several layers of cells; squamae large, incised and lacerate. 



Symphyogyna microcalyptra sp. nov. 



Plate 87 



DJoicous. Medium size ; pale to greenish brown in color ; loosely 

 caespitose. Fronds procumbent, somewhat rigid, bifurcate, ligulate, 

 regular, slightly biconvex; costa broadly oval, 10 cells thick, gradually 

 excurrent into wings, 3-3-2-2-1 ; wings 25 cells wide, unistratose ; 

 band of minute dark colored cells in middle of costa; cortical cells 

 larger than inner, margin of fronds distantly dentate, teeth ascending, 

 3 to 6 cells long, 2 to 3 cells broad at base, Calyptra very small, 

 trumpet shaped, corrugated when old, with numerous appendages and 

 archegonia near the mouth. Bracts lobate, lobes obtuse. 



Male fronds smaller, with bracts somewhat distant, not crowded 

 near apex. 



Dimensions. — Fronds 1 inch long; 4 mm. wide; segments 5 mm. 

 long; costa .25 mm. to .3 mm. thick at the middle X .75 mm. broad, 

 bracts 1 mm. long ; calyptra 2.75 mm. long X -75 mm. wide at mouth ; 

 perigonial bracts .5 mm. long. 



Habitat. — Kahikanui, near Whakapara, North Island, New Zea- 

 land, coll. W. A. Setchell, July 8, 1904, no. 19. Type, Herb. Univ. 

 Calif., no. 213723. 



Observations. — I have had the opportunity of comparing Setchell 's 

 specimens with various ones of S. obovata from Tasmania and New 

 South AVales, from which they differ in several particulars, and they 

 do not quite agree with Stephani 's description of S. obovata. 



The plants are brown to brownish green, with no trace of rose, more 

 rigid, fronds ligulate, not narrowty oval, cortical cells of costa larger 

 than inner (in **>. obovata they are of equal size) ; marginal teeth 

 erect, not projecting, 3 to 6 colls long, not 2, calyptra very small, 

 2.75 mm. long, not 10 mm. as Stephani says of S. obovata. My meas- 

 urements of S. obovata are 5 to 7 mm. long ; both the $ and ^ bracts 

 are more laciniate, the J* bracts more distant on the fronds, not 

 crowded near the apex.
