Rosa sancta, A. Richard. 



Abyssinia. With B. Abyssinica (B. Brown) the most southern 

 of all Bose-species. Seems entitled to record here, as it is still 

 cultivated at temples. Prof. Crepin has identified flowers from 

 ancient Egyptian tombs with this Bose, wbich must therefore have 

 some special value. 



Rosa sempervirens, Linne. 



From South-Europe through Southern Asia to Japan. Hardy 

 still at Christiania. One of the best rose-bushes for covering walls, 

 fences and similar structures. The flowers of this species also can 

 be utilised for rose-oil. 



Rosa setigrera, Michaux. 



North-Eastern America, where it is the only climbing rose-bush. 

 It deserves introduction on account of its extremely rapid growth 

 10 to 20 feet in a season. Its flowers however are nearly 

 inodorous. Other original species of roses are worthy of our 

 attention, Sir Joseph Hooker admitting about thirty, all from the 

 northern hemisphere. But on the snow-clad unascended mountains 

 of New Guinea and Africa south of the equator, perhaps new roses 

 may yet be discovered, as they have been traced southward to 

 Abyssinia already. 



Rosa spinosissima, Linne. 



Europe, North- Africa, Middle and Northern Asia. The Burnet- 

 Bose. Adapted for holding coast-sands ; unapproachable to pasture- 

 animals, and not spreading into culture-land or pastures like the 

 sweetbriar, B. rubiginosa, L. 



Rosmarinus officinalis, Linne. 



The Bosemary. Countries around the Mediterranean Sea, 

 extending to Switzerland. This well-known bush is mentioned 

 here as a medicinal plant. One of our best plants for large garden- 

 edgings. The oil, distilled from its foliage, enters into certain com- 

 positions of perfumery ; one cwt. of fresh herb yields about 24 

 ounces of oil [Piesse]. The flowers are much sought by bees. 

 Vilmorin states, that the seeds will keep for about four years ; but 

 the propagation from cuttings is easy also. Branches of this shrub 

 will keep off moths from wearing-apparel packed away. 



Rottboellia ophiuroides, Bentham. 



Tropical East- Australia. A tall perennial grass, praised by 

 Mr. Walter Hill for fodder. Hardy in regions free of frost. 



Royenia Pseudebenus, E. Meyer. 



South- Africa. Only a small tree, but its wood jet-black, hard 

 and durable ; in Capeland and Caffraria called ebony. B. pubescens
