With the exception of Chrysobalanea? and Sanguisorbea?, this order is so uniform in its appearance, that 

 Pbsa, the type from which all the other genera are to be considered variations, when justly understood, will 

 be found to contain every form of structure which is essential to the order. Having stated this, it will be at 

 once obvious, that if the other genera have such close affinity to P6sa, they must also bear a great analogy in 

 beauty. And this is, indeed, the fact, ^mygdalus and Prunus among trees, and Potentilla, Geum, and 

 others, among herbaceous genera, rival the rose in their blossoms, and, in many particulars, surpass that most 

 lovely of all flowers in foliage and general appearance. But it is not for charms alone of smell, or blossom, or 

 foliage, that this order has fixed itself so high in the estimation of mankind. It has also the rare merit of 

 comprehending all the most important of the fruits of the temperate regions of the world. Thus the apple and 

 the pear belong to Pyrus, the apricot to ^rmenlaca, the plum to Prunus, the peach and the nectarine to Persica ; 

 Eriobotrya produces the loquat, Mespilus the medlar, and, finally, the quince is borne by the Cydbnia. The 

 medical powers of many plants of this order are not less active than their fruit is excellent. The principal of 

 these is the well-known Prussic acid, which exists in abundance in the leaves and kernels of many genera, 

 especially of Prunus and Amf gdalus : it is the basis of Laurel water, which, when taken in small doses, acts 

 either as a violent purgative or as an emetic ; and, in stronger doses, is said to destroy irritability without 

 exciting inflammation ; these properties, however, although thus dangerous in the distilled water of the laurel 

 and other similar plants, can scarcely be said to exist in any important quantity in the plants in a state of 

 nature. The kernel of the bitter almond, for example, in which the Prussic acid is more abundant than usual, 

 is used for many culinary and other purposes without any bad effect. There are, however, cases in which it 

 is said to be dangerous to eat the fresh leaves or kernel ; as in the C6rasus virginiana, the leaves and fruit of 

 which are reputed in the United States to be poisonous to certain animals. Besides the Prussic acid, there are 

 several other principles which abound in the order. All Drupacea? yield a gum which is nearly allied to gum 

 Arabic, and which affords a strong evidence of the affinity that exists between Rosacese and Legumindsse. 

 A great deal of astringency is found in many species, whence different parts have been occasionally employed 

 as febrifuges, and as remedies for haemorrhage, diarrhoea, and dysentery. The root of the Tormentilla is used 

 for tanning in the Ferro Isles ; and that of the Capollim cherry in Mexico. The bark of C^rasus virginiana 

 is used as a febrifuge in the United States ; Potentilla r^ptans has been praised for the same properties. The 

 root of Geum urbanum has been found, by Milandi and Moretti, to contain one eleventh of its weight 

 of tannin ; it has been used both in America and Europe as a substitute for Jesuit's bark. The leaves of 

 Dryas octopetala in the north of Europe, of .Rubus arcticus in Norway, of Prunus spinbsa and Ct§rasus avium, 

 and of P6sa rubiginbsa, have been manufactured into a sort of substitute for tea. The bark of the root of 

 Gillenia trifoliata is remarkable in having, in addition to the astringency already mentioned, an emetic 

 property, on which account it is employed in North America as Ipecacuanha. It is said, that a similar power 

 exists in other Spiraeas. Cutting, division, and seeds ; by grafts, budding, and inarching. 



It must not be omitted, that the order Rosaceas nearly answers to the Icosandria of Linnaeus.
