Class VIII
- OCTANDRIA. 8 STAMENS.
THIS is a class, which, with reference to the plants which compose it, is of much consequence to the botanist and gardener. To the former it is recommended by the singular Melastomaceous plants which it contains, the gardener. To the former it is recommended by the singular Melastomaceous plants which it contains, the curious Michauxia , and the Jeffersonia, remarkable for its capsule, which opens like a snuff-box. To the gardener it possesses irresistible attraction, not only in the delightful Tetrathecas, Boronias, and Correas of New Holland, in the Dimocarpus of China, celebrated for its truly excellent fruit, and in the Fuchsias, Enotheras, Combretums, and Vacciniums, some of which form the pride of our hardy gardens; but also in the magnificent tribe of Heaths, which are certainly the most beautiful of plants under cultivation. This is abundantly attested by the splendid collections of Lee of Hammersmith, Rollison of Tooting, and last, but not least, of Loddiges of Hackney, where the precision of science is combined with the allurements of form and coloring.
