will scent the air for a considerable distance, leaves green 

 and lanceolate. D. 3Iargindfa is rare, yet it is to be seen 

 in a few of our collections. D. stricta is now Charhcoddia^ 

 stricfa, flowers blush, and in loose panicles. D. Draco is ad- 

 mired, and the most conspicuous of the genus. (Soil No. 11.) 



Erdntliemums, about ten species. E. j^ulchellum and E. 

 hicolor are the finest of the genus ; the former is in our col- 

 lections. Plenty of heat is indispensable to make it flower 

 in perfection; therefore it should have the warmest part of 

 the house, and it will produce flowers of a fine blue color 

 from December to April. The flowers of the latter are 

 white and dark purple, with a few brown spots in the white : 

 blooms from April to August. Drain the pots well, and 

 give the plants little sun during summer. (Soil No. 11.) 



EiKjenias, about thirty species, esteemed for their hand- 

 some evergreen foliage. This genus once contained a few 

 celebrated species, which have been divided. (See Jcum- 

 hbsa?) The Allspice tree, known as Mjjrtus Eimenta, is 

 now E. Pimenta ; the leaves are ovate, lanceolate, and, when 

 broken, have an agreeable scent. There are several varie- 

 ties, all of the same spicy fragrance. The plant is in very 

 few of our collections. E. J'rdyrans is sweet-scented ; the 

 flowers are on axillary peuduncles ', leaves ovate, obtuse. 

 (Soil No. 11.) 



Eiiphdrhia (spurge), a genus of plants disseminated over 

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

 tesque, and several of 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 appearance 

 to Cactus, but easily detected by the above perforation. 

 There is a magnificent species in our collections, which was 

 lately introduced from Mexico — (see Poinsettia). E. sjjlen- 

 dens flowers freely from December to May, and is of easy 

 culture. E, fulyens, same as jaquiniifldra, is a plant of a 

 slender willow looking habit, but produces a profusion of 

 flowers from the axil of each leaf, which renders it very 

 showy. The flowers of the whole genus are apetalous, and 

 the beauty of those described is in a brilliant scarlet bractca,
