plant, from which a distilled oil is rather copiously obtain- 

 able. One of our best plants for large garden edgings. 

 The oil enters into certain compositions of perfumery. 



Hubia cordifolia, L. (-B. Mungista, Roxb.) 



From the Indian Highlands through China and Siberia to 

 Japan ; also occurring in various parts of Africa, as far 

 south as Caffraria and Natal. This perennial plant produces 

 also a kind of Madder. Probably other species yield like- 

 wise Dye-roots. The genus is represented widely over the 

 globe, but as far as known not in Australia. 



Rubia tinctorum, L. 



The Madder. Countries around the Mediterranean Sea. 

 A perennial herb of extremely easy culture. The roots 

 merely dried and pounded form the dye. The chemical 

 contents are numerous ; in the herb : liubichloric and 

 Bubitannic acid ; in the root : Alizarin, Purpurin, Rubiacin, 

 Rubian, Ruberythrin acid, and three distinct resins ; also 

 Chlorogenin, Xanthin and Rubichloric acid. On the five 

 first depend the pigments produced from the root. Madder 

 is one of the requisites for Alizarin Ink. 



Rubus Canadensis, L.* 



The Dewberry of North America. A shrub of trailing 

 habit. Fruit black, of excellent taste, ripening earlier than 

 that of R. villosus, Ait., which constitutes the High Black- 

 berry of the United States, with large fruits. 



Eubus Chamssmorus, L. 



The Cloud- Berry. North Europe, North Asia, North 

 America, particularly in the frigid zone. A perennial but 

 herbaceous plant ; a pigmy amongst its congeners. Never- 

 theless it is recommended for introduction to our spongy 

 mossy alpine moors, on account of its grateful amber-colored 

 or red fruit. All the species can readily be raised from 

 seeds. -R. Arcticus, L., also with edible fruit, is in the high 

 north usually its companion. Near to us we have a similar 

 little herb, living for a great part of the year in snow, namely 

 Rains G-u,iviianit,s, Hook. It occurs oil the alpine heights 

 of Tasmania, from whence it might be easily transferred to
