Observations. — Stephani (Sp. Hep., p. 855, 1908) justly restores 

 the prior name of Lehmann & Lindenberg for this species, which has 

 a verywide distribution in Australasia and which varies within certain 

 limitations considerably. The comparison of actual specimens with 

 the 20 figures in Lindenb. & Gottsche's beautiful plate 7, Sp. Hep., 

 and the reduction of M. Sieierianum to a synonym confirm this. 



Stephani also refers Mastigohryum affinis Mitt. (Fl. N. Z.) to this 

 species. I have not had the opportunity of seeing it. 



The oblong leaves, arcuate antical margin, straight postical one, 

 with truncate, trilobate apex, segments often minutely denticulate, 

 easily enable the species to be determined. 



Bazzania fissistipa (St.) comb. nov. 



Mastigobryum fissistipum Steph., Sp. Hep., vol. 3, p. 533, 1909. 



Habitat. — Mamaku Bush, North Island, New Zealand; coll. W. A, 

 Setchell, 1904, no. 157. 



Observations. — Rhizoids very abundant proceeding from base of 

 underleaves. Leaves brown in color, ovate, truncate, vittate; under-

Lepidozia plumulosa Lehm. & Lindenb. 

 Plate 93 



Dioicous. Medium size; pale yellowish brown in color; caespitose; 

 flagelliferous. Stem broadly pinnate or bipinnate ; branches close, 

 ascending, patent (50°); cross-section shows 15 large cortical cells 

 and inner cells 15 to 20 per diam. Leaves obliquely inserted, divided 

 to the middle or below, segments 5 or 6, 6 cells long, 4 and 5 single 

 with 2 to 4 wide at the base, disc 8 cells broad at the base and 20 cells 

 broad at ui)per margin ; cells rather large, 4, 5 and 6 sided, quadrate, 

 walls thin, no trigones. Underleaves quadrifid to a little below the 

 middle, obcuneate, a little wider than the stem; segments 5-7 cells 

 long, 5 and 6 single, at the base 2 cells broad; branch underleaves
