ance, and it is easily cultivated in soil No. 1. It should 

 have frequent repottings when growing. 



Ruellia. There are a few species, very pretty free-flow- 

 ering plants, of easy culture. R. formosa, flowers long, 

 of a tine scarlet colour ; plant half shrubby. R.fulgida has 

 bright scarlet flowers on axillary long stalked fascicles. R. 

 persicifolia, with unequal leaves and light blue flowers, is 

 now called R. anisophylla. (Soil No. 10.) 



Russeliajuncea, a slender plant of an upright habit, pro- 

 ducing, when well-grown, a profusion of scarlet tubular 

 flowers, about one inch long each: it is of the easiest cul- 

 ture in soil No. 19. 



Sagus, Sago-palm. We are of opinion that the true 

 palm from which the sago of the shops is produced, has 

 not been introduced into our collections. It is very rare 

 in the most extensive collections of Europe, but it is not so 

 fine a plant as the one we have under the Sago, which is 

 placed in the natural orcfer of Cycadese; and Sagus is in 

 that of Palmse. The finest of this genus is S. vinifera 

 and S. Rumphii. They grow to a great height ; even in 

 artificial cultivation they may be seen from ten to twenty- 

 five feet. We have not introduced them here for their 

 beauty, but to prevent error. (Soil No. 12.) 



Soldndra, a genus of four species, remarkable for the 

 extraordinary size of their flowers, and are considered 

 beautiful. S. grandiflora and viridiflora are the best 

 two. The plants will bloom well if they are restricted in 

 pot room, and are only introduced as being worthy of cul- 

 tivation. If they are repotted once in two or three years, 

 it is sufficient, except where the plants are small and want 

 encouragement. (Soil No. 13.) 



Strelitzia, a splendid genus of noble-looking plants, all 

 of which do perfectly well in the green-house, except S. 

 augusta, the flowers of which are pure white ; the leaves 

 are very large, being nearly six feet long and eighteen 

 inches wide, and assume the appearance of the Banana 

 tree: it requires great space for its roots. (Soil No. 12.) 



Stephanotus florabimdus, a new and splendid evergreen 

 climber, with dark green thick leaves like a luxuriant wax- 

 plant, producing large bunches of pure white fragrant 

 flowers ; of easy culture in soil No. 13. 



Swietenia, (Mahogany tree,) the wood of which is cel-
