be taken into account. With the plants should be data con- 

 cerning migrational contrivances, seed production, pollination 

 and period of flowering, in addition to the name, date, and 

 place of collection, the vegetation form of the plant, &c., 

 and, if possible, photographs giving a general view of the 

 formation, its physiographic setting, nearer views of its seasonal 

 aspects, detail views of its structure (associations, zones, layers, 

 &c.), and flower portraits of the constituent species. 



Briefly referring to a few of the more characteristic and more 

 interesting of the plants of the district, the Coast Tea-tree is 

 found to occur more frequently and widely than was at first 

 thought. To the south it is,, no doubt on account of its being 

 less restricted, much more abundant, and the belt along the sea 

 front much wider. It is seen often almost at the extreme edge of 

 the formation about Springvale, on both sides of High-street, near 

 Ashburton, and the existence of hedges to the north of Burwood 

 leads one to suppose it originally grew there naturally. The 

 Swamp Paper-bark, Melaleuca ericijolia, naturally bounded the 

 formation north and south, and was the principal plant of the 

 creek valley. A lover of wet ground, it is not seen until the 

 region of the springs and swamps is come to in the eastern part 

 of our area. When conditions are favourable it is, like the 

 Coast Tea-tree, a socially exclusive plant, forming dense closed 

 associations with only a few climbers and wet-ground plants 

 existing for a little distance among its close-set stems. 



Concerning the plants found in the area but not charac- 

 teristic of the formation, the great majority are explicable by 

 their occurrence in adjoining formations. With regard to Oxy- 

 lobium ellipticum, Mr. Charles French has shown that it is an 

 escapee. The case is more difficult with Grevillea ilici folia and 

 Lasiopetalmn Baucyi, seemingly far removed from their natural 

 liabitats, and for them an explanation is not ventured at present. 



As to the map which accompanies these notes, 1 would 

 not have it supposed that it indicates all the patches of 

 formation at present existing, or even indicates them exactly. 

 I think, however, it may be taken to show all the larger areas. 

 For that it is by no means perfect, my excuse must be that 

 time and opportunity have not permitted me to traverse every 

 road in the district, and that the assistance I had hoped to get 

 from a quarter most likely to furnish more exact data was 

 unfortunately unobtainable. I hope, however, it may be helpful, 

 and enable members to visit localities which without its aid 

 might remaii\ unknown to them. 



The meteorological records so kindly given by Mr. P. Baracchi, 

 (iovernmcnt Astronomer, will hel]) to explain the vegetation 

 generally covering the district, and also the difference between 

 that occupying its eastern portion and that nearer to the sea.
