Art. XXXIV. — ISIote on the Behaviour in Cultivation of a 

 Chatham. Island Form of Coprosma propinqua, A. Cunn. 



By L. Cockayne, Ph.D. 



[Read before the Philosophical Institute of Conterburi/, lAth November, li)0(i.] 



That certain plants normally of upright habit, when exposed 

 to constant violent winds, especially when growing in physic- 

 ally or physiologically dry stations, assume a prostrate habit 

 is well known ; but such habit depends entirely upon their 

 environment, as culture experiments readily prove. Other 

 plants, again, growing naturally in similar positions, such as 

 Veronica chathamica and Hymenanthera crassifolia, are always 

 prostrate, and do not materially change in cidtivation. Co- 

 prosma propinqua is a plant of the former category. This 

 shrub, in its usual stations, such as lowland or subalpine scrubs 

 and fresh-water swamps, is erect with numerous more or less 

 divaricating branches. But when it grows on the coast — as, 

 for instance, on the shores of Foveaux Strait, at the base of the 

 Bluff Hill — it is iisually much " wind-shorn " and frequently 

 quite prostrate, being flattened against the rocks which emerge 

 from the peaty ground, and clinging closely to their surface. 

 But all transitions may be seen, from the wind-swept plant to 

 the normal, and there is no reason to expect that the former 

 form is in'^any way hereditary. 



Growing on the rocky face of the most easterly of the cones 

 of the volcanic hill known as the Horns, which forms a feature
