Among the most valuable flowering plants are those furnished by the order Rubiaceae, of which the well known Bouvardia may be taken as a type. There are other genera closely allied, which are also very beautiful, such as Pavetta, Rondoletia, Rogiera, and Ixora, of which we give an illustration here. Ixoras are particularly showy, and in places where specimen plants are cared for, always find a favor. Like Bouvardia they require some heat to bloom well in winter. There are a great number of species scattered chiefly over the Islands of the Indian Ocean, and new ones are being continually discovered or introduced for the first time to cultivation. The species here illustrated, I. splendida, is one of these recent introductions for which the floral world is indebted to the enterprise of Mr. Wm. Bull, Chelsea, near London.
