Family Malvaceae. 



Plagianthus divaricatus Forst. [J. F. A. ; J. B. A.] 



Common in salt-water marshes, as at Teddington ; or on stony 

 beaches — e.g., Port Levy. 



{^) Plagianthus cymosus T. Kirk. 



A specimen apparently belonging to this species was found on Moimt 

 Pleasant, behind Lyttelton, by Cockayne and Petrie ; but in spite 

 of numerous searches I have been unable to rediscover the plant. 

 Cockayne now thinks it may have been a flowering plant of the 

 juvenile form of P. hetulinus. 



Plagianthus hetulinus A. Cunn. [J. F. A. ; J. B. A. ; L. C] 



Abundant in the forest. 



Hoheria angustifolia Raoul. [R. ; J. F. A. ; J. B. A. ; L. C] 



Common in the opener forest and by roadsides. (Akaroa is the type- 

 locality.) 



Family Guttiferae. 



Hypericum gramineum Forst. f. [J. F. A. ; J. B. A. ; L. C] 

 Tussock-grasslands. 



Hypericum japonicum Thiinb. [J. F. A. ; J. B. A. ; L. C] 

 Tussock-grasslands.

Family Violaceae. 



Viola filicaulis Hook, f . [J. B. A.] 

 Hilltops chiefly. 



Viola Cunninghamii Hook. f. [J. F. A. ; J. B. A. ; L. C] 

 Tussock-grassland and swamps. 



Melicytus ramiflorus Forst. [J. F. A. ; J. B. A. ; L. C] 



Everywhere common. Known on the peninsula as "' cow-leaf " or 

 " whity-wood." The North Island Maori name, ' mahoe," is quite 

 unknown here, as is also the Otago " ini-ini.'" 



(^) Melicytus lanceolatus is recorded only by J. B. A. I have not 

 seen it nearer than Peel Forest. 



°{'^) Melicytus micranthus Hook. f. var. microphyllus Cheesm. [J. B. A.; 

 L. C] 



Hymenanthera crassifolia Hook. f. [J. B. A. ; L. C] 



Abundant in rocky places, particularly near the hilltops. A rigid 

 shrub with spinous divaricating interlacing branches, forming a mat 

 closelv appressed to stones and chff- faces. The berries are foimd on 

 the underside of the mat, and remain white when not exposed to light, 

 but thereafter become dark blue — almost black. It has been regarded 

 as a coastal plant, but is not so here. 



The species is extremely plastic, probably as much so as Discaria 

 foumatou has been shown to be by Cockapie. In caves and moist 

 forests it loses its thorny and divaricating character, forms long pliant 

 branchlets pubescent towards the tips, and becomes clothed with some- 

 what larger leaves. In this form it is perhaps not different from 

 H. dentata.
