low bracteced variety ; but we are not aware of its being for 

 sale in this country. When the plant is grown in pots during 

 summer, it must be repotted every month to encourage its 

 rapid growth. (Soil No. 18.) 



Rhdpis, a genus of palms that will grow very freely with 

 heat and room at the roots. R. flabdllfdrmis is an erect 

 growing palm, with a spreading head. It is a native of China.

Rondeletia specidsa is a new and rare plant, in every re- 

 spect equal, if not superior, to Ixbra edecinea ; its large 

 corymbs of orange-red flowers have a very striking appear- 

 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 flowering 

 plants, of easy culture. R. formbsa, flowers long, of a fine 

 scarlet colour; plant half shrubby. R. fulgida has bright 

 scarlet flowers on axillary long-stalked fascicles. R. persi- 

 cifoUa, with unequal leaves and light blue flowers, is now 

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



Russelia jtincea, 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 culture 

 in soil No. 19. 



S&gus, 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 order of Cycadece; and Sagus is in that of Palmce. 

 The finest of this genus is S. vinifera and S. Riimphii. 

 They grow to a great height; even in artificial cultivation 

 they may be seen from ten to twenty-five feet. We have not 

 ; ntroduced them here for their beauty, but to prevent error.

Soldndra, a genus of four species, remarkable for the ex- 

 traordinary size of their flowers, and are considered beautiful. 

 S. grandtflbra and S. viridiflbra are the best two. The 

 plants will bloom well if they are restricted in pot-room, and 

 are only introduced as being worthy of cultivation. If they 

 are repotted once in two or three years, it is sufficient, except 

 where the p'ants are small and want encouragement. (Soil 

 No. 13.)
