Isotachis grandis, Carr. et Pears. 



Pig. 7. Leaf (flattened) ; x 17. 

 Pig. 8. Stipule; x 17. 



Additional notes on the habitats of this plant : It grows 

 on the nearly flat portions of the summits of the hills already 

 named, in the drainage, which flows very slowly, varies in 

 width from 1ft. to several feet, and is about lin. in depth, 

 with a muddy bottom. It is a very beautiful plant, being 

 lustrous and nearly black. Like a large number of New 

 Zealand plants, it appears to be very local. It is not plen- 

 tiful in the localities named, which up to the present are 

 the onlv places where it has been found. Fruit not known.

Here, as in the previous part of this paper, no attempt is 

 made to give a complete synonymy of the species. Only such 

 references are given as will introduce the student to the chief 

 literature of the subject, where he will find full descriptions, 

 and also fuller lists of synonyms, which will enable him to 

 pursue his investigations. I have to express my thanks to 

 Major Beinbold»for his kindness in identifying a number of 

 specimens.

This plant has not been collected lately, but might be 

 overlooked on account of its smallness.
