CELASTRAGEjE. 



Euonymus eurojjceus. 



and angustifolius have from two to five in each series, and they then 

 become horizontal or nearly so, their raphes facing. In one species 

 from Ceylon, which has constituted the genus Glyptopeialum^ because 

 the base of the four petals presents two more or less decided inden- 

 tures, there is only one ascending ovule. In an Eastern Asiatic species, 

 E, alatus^ the ovary becomes more lobed with 

 age ; it has formed a genus Melanocarya ^. In 

 another Indian species, with many-ovuled cells, 

 E. grandiflorus Wall., the petals are fimbriate 

 and more or less prominently crested ; hence, 

 the generic name Lophopetalum,^ But these 

 differences of detail seem to us too unimportant 

 to justify the making of distinct genera, and 

 we shall consider them only as sections of the 

 genus Euonymus. Taken thus, it includes 

 about forty-five species,* arborescent or fru- 

 tescent, sometimes scandescent. They inhabit 

 chiefly the temperate regions of Europe, Asia, 



and North America, and are more rare in the tropical parts and in 

 Oceania. The branches are rounded or oftener tetragonal, leaves 

 opposite, petiolate, entire or serrate, persistent, with 

 two small caducous stipules. The flowers are axillary, 

 in cymes, often compound, generally biparous, often 

 few-flowered and sometimes reduced to a single 

 flower. 



Pachystima^ a small shrub of the western mountains 

 of North America, has almost all the characteristics of 

 Euonymus : leaves opposite, entire or oftener serrate ; 

 flowers 4-merous and 4-androus. But its ovary has 

 only two incomplete and biovulate cells. The ovules 

 are ascending, and the fruit an oblong capsule, dehiscing late.
