NATURAL HISTORY OF PLANTS. 



belong to the same family as the RuUacem. 3. D. Hookee, however, 

 has kept them separate in the great and comprehensive work on the 

 family of the Rubiacem ^ given some years since. It there comprises 

 340 genera distributed in twenty-five tribes, classified in three series 

 according as the ovules are sohtary, geminate or indefinite in number. 

 We have reduced the number of tribes or series to fifteen, comprising 

 203 genera ^ and about 4500 species r 



' Gen. u. (1873) 7, 1226, Ord. 84. 



' Omitting doubtful genera, imperfectly 

 kno'wii, the numter of which is oonsiderahle.

' with reflexed caudate summit and tubular style 

 {Apocynea ?).
