CLASS 10. DECANDRIA. 



(Containing Plants with Ten Stamens.) 



A numerous class, containing many important foreign plants, 

 but none of English growth of any value, except for ornament, 

 but to this end many of them are greatly conducive. Several 

 of those described are handsome ; others less common are worth 

 attention. We have in woods the leafless singular plant, called 

 Bird's-nest also the Winter- Green, the Marsh Andromeda, 

 the Strawberry-tree and the Bear Berry, the Golden Saxifrage, 

 the Soap-wort, some of the fragrant tribe of the Pinks, the 

 Wall Penny- wort, so common in North Wales, and some others. 

 Among the interesting useful and ornamental plants of Decan- 

 dria may be mentioned the Cassia, Logwood, Lignum Vitas, 

 Fraxinella, Quassia, Kalmia, Ledum, Rhododendron, Andro- 

 meda, Arbutus, Hydrangea, Saxifrages, Soap-wort, Campions, 

 Stone-crops, Oxalis, Rose Campion, and numerous others.
