and remarkable habit, in both of which it differs widely from its congeners. 

 It is most nearly related to P. vh-gata, Vahl., but differs in the distant, 

 erect leaves, which are broader and less acute than in that well-known 

 species. In its slender habit and distant leaves it approaches the Tasmanian 

 P. JiHformis, but the flowers are very different, and the stems although 

 extremely slender are not flexuous. 



Two or three small specimens of our plant are preserved in the Herba- 

 rium of the Canterbury Museum, and were collected during Dr. Haast's 

 earlier exploration in the Southern Alps. The precise habitat is unknown, 

 but there is reason to believe that they were collected in the vicinity of the 

 Porter Eiver. I have received small specimens from Mr. Armstrong, 

 marked, *' habitat unknown," but probably obtained from the same locality 

 as those of Professor von Haast.

Lagenophora emphysopus, Hook. f. 



This plant was brought under my notice as a native of the colony by Mr. 



W. H. Field, a student of Wellington College, who discovered it on hills 



near Evans Bay ; shortly afterwards it was obtained at Paikakariki by Mr.
