ErytJu-inas (Coral tree), a genus containing about thirty 
species of leguminose, scarlet-flowering plants. Several 
species are greatly esteemed for their beauty and profusion 
of flowers, which, in well-established plants, are produced 
in long spikes. E. coraUodendrum blooms magnificently 
in the "West Indies, but in our collections has never flowered. 
Perhaps if it were kept dry during its dormant season, which 
is from November to January, and when growing greatly 
encouraged, it might produce flowers. E. specibsa is a splen- 
did flower, leaves large, ternated, and prickly beneath ; 
stem prickly. E. pufasc&ns is valued for its large, peculiar 
brown pubescent leaves. E. princeps is quite a new species, 
and is represented as being the finest of all the Erythrinas, 
and exhibits its rich crimson flowers in great profusion ; to 
make them grow well and bloom freely, they require plenty 
of pot-room-; indeed, while in a growing state, they should 
be repotted every month. In regard to E. herhdcea, which 
is a native of the Carolinas, and frequently treated as a hot- 
house plant, it is our opinion that it would be more perfectly 
grown if planted about the first of the month in the garden ; 
and, when growing, if well supplied with water, it would 
flower from July to September. About the first of Novem- 
ber lift the roots and preserve them in half dry earth. E. 
laurifblia and E. cristagdlli are likewise often treated as 
hot-house plants, and in such situations they cast prema- 
turely their first flowers by the confined state of the air. 
They will keep in perfect preservation during winter in a 
dry cellar, half covered with earth, or entirely covered with 
half dry earth ; consequently, the best and easiest method 
of treatment is to plant them in the garden about the first 
of May, and, when growing, if the ground becomes dry, 
give them frequent waterings. They will flower profusely 
three or four times in the course of the summer. 
We freely recommend the last species to all our patrons, 
confident that it will give ample satisfaction, both in profu- 
sion of flower and beauty of colour. The soil they are to be 
planted into should be rich and well pulverized ; or, if they 
are kept in pots, they must be enlarged three or four times, 
when they are in a growing state, to make them flower per- 
fectly; otherwise they will be diminutive. (Soil No. 13.)
