1923] Pearson : Notes on a Collection of Neiv Zealand Hepaticae 327 



Observations. — The only species near it, from Stepliani's descrip- 

 tion of New Zealand Frullaniae, is F. falciloha Tayl. ; but this is a 

 much more robust plant, with underleaves proportionately large, 

 not so regularly circular, often a little angular and slightly dentate, 

 lobe of bract acute and sometimes dentate, lobule dentate and 

 bracteole dentate. 



Stephani does not record F. falciloha Tayl. from New Zealand, but 

 Mitten does (AVairapara Valley on bark, Wm. Colenso). I have 

 specimens from New Zealand collected by Colenso, ex herb. Curnow, 

 named F. falciloha, which are quite different from the description, 

 lobule spiniferous, underleaves irregular in shape, deeply, divided 

 with margin more or less dentate, 



FruUania (Diastoloba) rostrata (Tayl.) Hook, et Tayl. 



Syn. Hep., p. 445; Stephani, Sp. Hep., vol. IV, 1911, p. 661. 

 Jungermannia rostrata Tayl., Jour, of Bot., 1845, p. 87. 



Leaves apiculate, perianth triplicate, narrowly oblong, long beak, 

 bracts lobe lanceolate acute or acuminate, entire, lobule same only 

 smaller. 



Habitat. — Bush near Waiotapu, North Island, New Zealand; coll. 

 W. A. Setchell, 1904. With no. 159. 



Anthoceros? nostocoides sp. nov. 



Plate 103 



Sterile. Largish in size; olive green in color; densely stratose. 

 Fronds bi-trifurcate, lobes erecto-patent (30°), linear, regular, slightly 

 plano-convex, 3 to 4 cells thick at the middle, gradually thinning to 

 margin which is one cell thick ; cortical cells very small and indistinct, 

 inner large and irregular in size, hyaline ; lobulate ; lobules few, 3-4 ; 

 cuticle smooth; postical side with numerous narrow oval Nostoc 

 colonies imbedded in the fronds. 



Dimensions. — Fronds 1 to 2 inches long, 3 to 5 mm. wide, .2 to .3 

 mm. thick ; Nostoc colonies .5 mm. long X .25 mm. wide. 



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

 Setchell, 1904, no. 14. Type Herb. Univ. Calif., no. 213714. 



Observations. — Although the plant was collected in considerable 

 quantity I have not been able to find any trace of J* or 5, so am not 

 able to say to ^Yhich sub-genus of Anthoceros the species belongs. 

 Mitten records only 4 species of Anthoceros from New Zealand, all 

 very different from the above, and Stephani records 6 Megaceros and 

 3 Anthoceros, to none of which does this species agree according to 

 his descriptions.
