OCTANDRIA. 
Class VIII. 
Class VIII. — OCTANDRIA. 8 Stamens. 
This is a class, which, with reference to the plants which compose it, is of much consequence to tlie botaiust 
and 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 gar- 
dener 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, CEnotheras, 
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 at- 
tested by the splendid collections of Lee of Hammersmith, RoUison of Tooting, and last, but not least, of Lod- 
diges of Hackney, v/here the precision of science is combined with the allurements of form and coloring.
