Petrie. — On the Flowering Plants of Otago. 549 



nion on mountains of interior and W., there ascending to 

 3,000ft. or more. This plant is steadily spreading on hill- 

 sides denuded by fire or close cropping by sheep or rabbits. 



Haloragis depressa, Hook. f. — Abundant in open and even 

 scrubby lands, and very variable. 



Haloragis micrantha, Hook. f. — Moist hillsides throughout 

 the district ; local, but widespread. 



Haloragis uniflora, T. Kirk. — Dunedin ; Kelso ; Maniototo 

 Plain ; and plains of Upper Clutha and its affluents. I 

 cannot distinguish this from H. depressa, Hook. f. At 

 Signal Hill, near Dunedin, all states between H. uniflora 

 and H. depressa can be readily found. 



Haloragis spicata, Petrie. — Eiver- flats at head of Lake 

 Hawea. At Kew this is reckoned a distinct species, but a 

 fuller knowledge of intermediate forms may possibly unite 

 it with H. depressa. Such intermediate forms are as yet 

 unknown. 



Myriophyllum elatinoides, Gaudichaud. — Not rare in 

 lagoons and sluggish streams. Lake Waihola; Taieri 

 Plain ; Maniototo Plain ; &c. 



Myriophyllum vari^folium. Hook. f. — Not rare in same 

 stations as the foregoing species. 



Myriophyllum pedunculatum. Hook, f.— Not uncommon in 

 miry bogs and wet grounds. Taieri Plain ; Inch-Clutha ; 

 Lumsden ; Eoxburgh ; Maniototo Plain ; &c. 



Gunnera monoica, Eaoul. — Common on wet banks. 



Gunnera ovata, Petrie. — Kaikorai Swamp; Inch-Clutha; 

 Catlin's ; Hindon ; and many boggy localities, among 

 Sphagnum. 



Gunnera dentata, T. Kirk. — Not rare in the silt of river- 

 beds in the mountain valleys of the far W. Matukituki 

 Valley ; Hunter River ; head of Lake Wakatipu ; Lake Te 

 Anau. This is a strictly western species. It seems not to 

 pass E. of the Lake District, and is absent from tlie 

 middle region of Otago. 



Callitriche verna, L. — Not rare in slow streams; more 

 common inland than in the E. and N. 



Leptospermum scoparium, Forst. — Abundant in scrub on 

 clay hills throughout. 



Leptospermum ericoides, A. Rich. — As wide-spread as the 

 preceding, but not so plentiful. 



Metrosideros lucida, Sm. — Common in forests of the S. 

 Northern limit on E. is at Taieri Mouth. A few small 

 trees grow at Lake Wakatipu.
