its bitter-almond flavour. See specimens of this fam- 

 ily in Engl. Bot. t. 1383, 706, 841, 842. The Myr- 

 tle tribe (133) is another natural order, comprehended 

 chiefly under Icosandria Monogynia, abounding in a 

 fragrant and wholesome aromatic oil. These are plen- 

 tiful in New Holland. See TV. of Linn. Soc. v. 3.

 aromaticus, the Clove, should on every account be 

 removed hither, 



ti. Pentagynia. In this order it is most convenient to 

 include such plants as have from two to five styles, 

 and occasionally, from accidental luxuriance only, 

 one or two more. An example of it is the very natu- 

 ral family of the Pojnacea, as Pyrus, the Apple, Pear, 

 &c. Engl. Bot. t. 179, 350, 337 ; and Mespilus, t, 

 1523, Exot. Bot. t. 18, 85. In this famih some 

 species of the same genus have five, others three, two, 

 or only one style, and a corresponding number of 

 seeds. Spircca, nearly allied to it, stands here, most 

 of its species having five styles, though some have a 

 much greater number ; see Engl. Bot. t. 284, 960. 

 Mesemhryanthemum, a vast and brilliant exotic genus, 

 of a succulent habit, abounding in alkaline salt, and a 

 few genera naturally allied to it, make up the rest of 

 the order. 



3. Polygynia. An entirely natural order of genuine 

 Rosaceous flowers, except possibly Calycanthus.
