 red ; in reference to the colour of the fruit of

 Or. Rosacea. An extensive and interesting 

 genus of plants. The shrubby kinds of Bramble 

 grow best in a rich loam ; and are readily in- 

 creased by suckers from the root, or by cuttings. 

 The herbaceous species thrive best in peat soil, 

 and are likewise propagated by suckers. The 

 well known and much-esteemed Raspberry is the 

 fruit of Rubus Idmus and its garden varieties. 

 The fruit of R. Chamosmbrus is acid, and plea- 

 sant to the taste . It is known by the name of 

 Cloudberry, from the plants being found in 

 high situations. The Scottish Highlanders and 

 Laplanders esteem it one of their most grateful 

 and useful fruits, more especially on account of 

 its long duration. Synonymes: 1, R. pistil-
