Dioieous. Medium size ; stems, reddish or greyish brown in color ; 

 intricately caespitose. Stems narrowly pinnate, sometimes irregu- 

 larly ramose, pinnae unequal in length, sometimes long, ascending, 

 erecto-patent (30°). Leaves imbricate, concave, lobe broadly oval, 

 appendiculate, appendix triangular, acute ; lobe galeate, mouth wide 

 truncate. Underleaves three times broader than the stem, sub- 

 circular, slightly cordate or decurrent, very shortly bidentate, seg- 

 ments acute and apiculate. 



Androecia on short terminal branches, globose or oblong-globose, 

 or intercalular, 4-5 pairs of bracts, bracts divided to the middle, lobe 

 obtuse, lobule acute, entire or with a minute tooth, bracteole spath- 

 ulate, retuse. 



Dimensions. — Stems II/2 inch long, with leaves 1.25 mm. wide; 

 diam. .2 mm. ; leaves, lobe .75 mm. X .7 mm., lobule .3 mm. X -2 mm. ; 

 cells .02 mm. ; underleaves .5 mm. X -5 mm., .5 mm. X .4 mm. ; peri- 

 gonial bracts, lobe .5 mm. X -3 mm. ; lobule .4 mm. X -25 mm. 



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

 May 16, 1904. 



Observations. — Stephani wrote to me some years ago that he had 

 received from the Rev. Wm. Colenso 600 packages of New Zealand 

 Hepatics. The species here named by him after Colenso is remark- 

 able in having the large appendix of the leaf triangular and acute 

 in shape. This can be well seen only by detaching a leaf from the 

 stem and flattening it out with the cover glass. It is a remarkable 

 character and I have not seen it in any other species. 



Stephani in his description of the species says he had not seen 

 the male plant. On Setchell 's specimens there are several male stems.
