On edges of woods of Chatham-Island. 



The plant presents the normal form. It is a tall climber ; the 

 leaves are not rarely three-lobed and vary considerably in size. 



The limits between M. australis, M. appressa, M. axillaris (M. 

 parvifolia, Meisn. in Linnsea, 1853, 362) and M. complexa have to 

 be traced anew. In Australia felix M. appressa occurs always as a 

 lowlands plant, whilst M. axillaris is restricted to subalpine moun- 

 tains. It seems evident from plants collected in New Zealand by 

 Mr. Travers senior and Dr. Haast, that M. complexa exhibits merely 

 a luxuriant state of M. axillaris. 



In the Fragmenta Phytographise Australise (vol. iv. 131) it has 

 been pointed out why at least the Australian species of Muehlen- 

 beckia might well be transferred to Polygonum.

Chatham-Island, on stems of fern-trees. 



Mr. Travers's plant is fruit-bearing. The capsules are about J" 

 long, narrow-elhpsoid and strongly ribbed. 



Pterostylis Banksii.

On grassy places of Chatham-Island. 



The plants of Mr. Travers's collection are unusually dwarf, some 

 only of a finger's length.
