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

 China. (Soil No. 12.) 



RondeUtia speciosa is a new and rare plant, in every re- 

 spect equal, if not superior, to Ixdra cdcrinea ; its large 

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

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

 Lave frequent repottings when growing. 



RueUia. There are a few species, very prettj^ flowering 

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

 scarlet color; plant half shrubby. R. fuhjida has bright 

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

 cifbliaj with unequal leaves and light blue flowers, is now 

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



Russelia juncea, 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. 



SaguSj 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 Cycadese] and Sagus is in that of Palmse. 

 The finest of this genus is S. vinifera and S. Rumpliii, 

 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.) 



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

 traordinary size of their flowers, and are considered beautiful. 

 S. grandiflbra and S. viridiflbva 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 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. au- 

 giista, 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 )
