NATURAL mSTOBY OF PLANTS. 



pericarp of no great thickness, surrounded by the persistent calyx, 

 which becomes fleshy. Within, imbedded in a soft pulp, are 

 numerous seeds, whose integuments are covered with hairs at the 

 margin, and contain a small embryo near the apex of the fleshy 

 albumen. D. sjjcciosa is a fine tree with alternate, oval-acute 

 dentate, penninerved leaves, the secondary nerves oblique, pro- 

 jecting, parallel. The flowers are solitary terminal. 



As a separate genus near Dillenia was formerly placed Colbertia,^ 

 which only differs from it in two unimportant points. The flowers, 

 smaller than those of B. speciosa, either solitary or in bunches, have 

 yellow, instead of white petals. The seeds, either imbedded in a 

 soft pulp or surrounded by a thin pericarp, have no hairs on the

surface. The number of cells in the ovary may be reduced to five, 

 as in the species hence named B. peiitagyna^ The ovules horizontal, 

 or more or less ascending, are arranged in two or more rows in 

 each cell. Thus limited,-^ the genus Dillenia includes eight or ten 

 species which grow in India, and the neighbouring portions of the 

 Indian archipelago." 



The genus Wormict' is also very near Dillenia, from which it has
