This important order yields us our most beautiful flower, the Rose, of which there are a great many varieties, among which the Dog-rose—that beautiful ornament to our hedges—deserves to hold a conspicuous place, also the Sweetbriar or Eglantine. The rose is used in Turkey and Persia for obtaining that most valuable and delicious perfume, "Otto of Roses." It is made by distilling a portion of water from several quantities of fresh roses, until it becomes saturated with the volatile oil. This water is then exposed to the open air, and, in the cool night time, drops of the otto collect on the top, from which it is carefully gathered, and the same water again distilled from a fresh quantity of roses. Besides the Rose tribe, this order contains some of our most valued fruits. The Apple, Pear, and Strawberry belong to it, also the Almond.

This is the tuber of the "Solanum tuberosum." The following account of the introduction of the Potato into England is from the "Penny Cyclopædia":—

"Queen Elizabeth, in 1584, granted a patent 'for planting and discovering in new countries, not possessed by Christians,' and, under this sanction, some ships, principally equipped by Sir Walter Raleigh, sailed with him to America. Thomas Harriott (afterwards known as a mathematician) who accompanied the adventurous squadron, transmitted to England the description of a plant, called Openawk by the natives of that part of America, which the courtier-like gallantry of Raleigh had named 'Virginia.' Harriott described the Openawk as having the roots round, and 'hanging together as if fixed on ropes, and good for food either boiled or roasted.' Girarde in his Herbal a few years subsequently, distinguished the plant by a plate, and not only confirmed the assertion that it was an indigenous production of Virginia, whence he himself had obtained it, but supplied some curious details of its qualities, and of the various modes in which it might be dressed for the table. But the Potatoe had been known in Spain and Portugal at an earlier period, and it is from the latter country that we most directly derive the name by which we know it. This is easily shown; although the natives of South America called the plant by the name 'Openawk,' those of the South, more particularly the inhabitants of the mountains of Quito, called it 'Papas,' which the Spaniards corrupted into 'Battata,' this again their neighbours in Portugal softened into 'Ba-ta-ta' (da terra), to which 'potato' is a very close approximation."
