growing palin, with a spreading head. It is a native of 
China. (Soil No. 12.) 
RondeUtia specidsa is a new and rare plant, in every re- 
spect equal, if not superior, to Ixbra cdccinea ; 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. formosa, flowers long, of a fine 
scarlet colour; plant half shrubby. R. fulgida has bright 
searlet flowers on axillary long-stalked fascicles. R. persi- 
cifolia, with unequal leaves and light blue flowers, is now 
called R. anisopliylla. (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. 
Sdgtis, 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 Palmse. 
The finest of this genus is *$'. 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 
introduced them here for their beauty, but to prevent error. 
(Soil No. 12.) 
Soldndra, a genus of four species, remarkable for the ex- 
traordinary size of their flowers, and are considered beautiful. 
S. grandlflbra and S. virid flora 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. augiis- 
ta, 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.)
