Lophocolea sp.? 



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

 Setchell, April 22, 1904. 



Observations. — I picked out a few stems of a small Lophocolea 

 with androecia which I have not been able to refer to any in Mitten's 

 or Stephani's lists of New Zealand species; the leaves are broadly 

 ovate, .7 mm. X .6 mm., to shortly trigonous, .7 mm. X .6 mm., broad 

 base with narrow apex, bidentate, sinus shallow, teeth 3 to 5 cells 

 long; underleaves connate on one side with leaf obcuneate, bifid to 

 below the middle, segments entire or with a small tooth near the base 

 on either side. 



Lophocolea heterophylloides Nees 



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

 May 16, 1904, no. 23. 



Observations. — This is a small sterile form, w^ith leaves usually 

 entire or retuse, occasionally a bifid leaf near the base of the stem 

 is found, but the numerous minute flagelliferous shoots are alwaj^s 

 deeply bifid. 



Chiloscyphus echinellus (Lindenb. & Gottsche) 



See P. Lyallii Mitten, Fl. N. Z., 11, p. 141. 



Habitat. — Growing on Plagiochila Kirkii Mitt., Mamaku, North 

 Island, New Zealand ; coll. W. A. Setchell, April 22, 1904. 



Observations. — This is often confused with Lophocolea muricata. 

 I have fine specimens sent to me under this name, collected by S. 

 Chadwick, Hawke 's Bay, North Island ; also, from the same collector 

 and same station, the true plant.
