the flowers are on axillary peduncles ; leaves ovate, obtuse. 

 (Soil No. 11.) 



Euphorbia, (spurge,) a genus of plants disseminated over 

 every quarter of the globe ; a few are beautiful, many gro- 

 tesque, and several the most worthless weeds on the earth. 

 There are about two hundred species, and from all of them, 

 when probed, a thick milky fluid exudes. Those of the 

 tropics are the most curious, and very similar in appear- 

 ance to Cactus, but easily detected by the above perfora- 

 tion. There is a magnificent species in our collections, 

 which was lately introduced from Mexico (see Poinset- 

 tia.) E. splendens flowers freely from December to May, 

 and is of easy culture. E.fiilgens,same asjaquiniifldra, 

 is a plant of a slender willow-looking habit, but produces a 

 profusion of flowers from the axil of each leaf, which ren- 

 ders it very showy. The flowers of the whole genus are 

 apetalous, and the beauty of those described is in a brilliant 

 scarlet bractea, which is very persistent. They must have 

 plenty of pot-room. (Soil No. 9.) 



Erythrinas, (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. corallodendrum blooms magnificently 

 in the West Indies, but in our collections has never flow- 

 ered. 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. 

 speciosa is a splendid flowerer, leaves large, ternated, and 

 prickly beneath; stem prickly. E. pubescens 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. herbdcea, 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 grow- 

 ing, if well supplied with water, it would flower from July 

 to September. About the first of November lift the roots
