1923] Pearson : Notes on a Collection of Netv Zealand Hepaticae 323 



Ohservations. — As I find several male stems of the same small 

 size as the others, I take it that the stems met with are normal in 

 size. So far as I know no Isotachis like it has been described before. 



Lepicolea scolopendra (Hook.) Dum. 



Rec. d'obs., 1835, p. 20. 



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

 Setchell, April 22, 1904. With no. 28. 



Lepidolaena clavigera (Hook.) var. Stangeri Gottsche 



Hal it at. — Mamaku, North Island, New Zealand ; coll. W. A. 

 Setchell, April 22, 1904. With no. 4. 



Observations. — The reducing of L. Taylori (Gottsche) to a variety 

 of L. clavigera (Hook.) by Mitten (Handb. Fl. N. Z., p. 529) may 

 possibly account for the uncertainty which several collectors have 

 shown as 1o L. Taylori, to judge by the various specimens I have 

 received under wrong names. 



Mitten simply says (when making it a variety) : ''var. Taylori 

 Cauline leaves toothed and spinose on the ventral margin," but 

 Gottsche, the founder of the species, saw more differences. The 

 underleaves, to mention another character, are quite different. They 

 are deeply quadrifid, with the segments spreading and irregularly 

 laciniate-spinulose. In L. clavigera they are not so deeply divided and 

 are entire, slightly calcarate at the base. 



Lepidolaena papebrifolia (Gottsche) has underleaves much 

 nearer to L. Taylori than has L. clavigera, but the segments are still 

 more spinulose and ciliate than L. Taylori and can be at once dis- 

 tinguished from that species by the absence of laciniae on the antical 

 base of the leaves. 



The var. Stangeri G. to which Setchell 's specimens belong, differs 

 from type by having its branch-leaves sometimes dentate-serrate. 



Schistochila nobilis (Hook.) Dum.
