Grotons. — About twenty-eight species, few of them de- 
serving cultivation ; but the genus is celebrated for its 
beautiful G. pictus, leaves oblong-lanceolate, variegated with 
yellow, and stained with red, flowers small green, or axillary 
spikes. C. variegatus, variety latifblia, is finer than the 
original variegatus ; the nerves in the leaves are yellow, and 
the leaves lanceolate, entire, and smooth. To make them 
grow freely, give them the warmest part of the hot-house, 
and drain the pots well. (Soil No. 13.) 
Cycas, four species, generally called Sago palm, as an 
English name. The plant from which Sago is extracted, 
belongs to another genus, (see Sdgns.) C. revoluta is a 
well-known palm, and will keep perfectly well in the green- 
house. We have seen a beautiful specimen of it which is 
kept every winter in the cellar; but those that are kept so 
cool in winter only grow every alternate year, while those 
that are kept in the hot-house grow every year, which shows 
that heat is their element. C. circindlis is a large-growing 
species; the fronds are much longer, but not so close and 
thick. C. glaiica is a fine species : the foliage is slightly 
glaucous. They require plenty of pot-room, are much in- 
fested with the small white scaly insect, and ought to be 
frequently examined and carefully washed as prescribed in 
January. (Soil No. 12.) 
Gyprftpidivm insigne is a very beautiful nepal species of 
this curious Ladies' Slipper plant. The flowers have a waxy 
appearance, and very much in the shape of an Indian shoe ; 
the colours are green and purple ; it likes a moist, half- 
shaded situation. (Soil No. 16.) 
Gyrtocercas reflexus, or Soya coriacea, a new dwarf wax- 
plant of magnificent appearance, either for foliage or bloom, 
which it produces in great profusion from the axils of almost 
every leaf; it is a native of Manilla; it grows freely in Soil 
No. 18. 
Dracaenas, Dragon-tree, about twelve species of Asiatic 
plants varied in character. D. Ferrea is plentiful in our 
collections, and will keep in the green-house ; but the foliage 
is not so well retained as when kept in the hot-house; the 
leaves are lanceolate, acute, of a dark crimson colour. D. 
termindlis, striped-leaved; D. fragrans, when in bloom,
