 leaves. Linn. 14, Or. 2, Nat. Or. Prptedceos. 

 A genus of splendid evergreen shrubs, with 

 handsome foliage, and heads of yellow flowers. 

 L. argtnteum, or the Silver-tre6 grows to the 

 "height of fifteen or twenty feet, with beautiful 

 silky leaves ; it is on that account admirably 

 adapted for ornamenting conservatories. They 

 grow best in loam and peat, with a small por- 

 tion of sand, provided the pots are carefully 

 drained, and not overwatered. Cuttings of 

 the ripened wood will root readily planted in 

 sand, under a glass. Synonyme : 1, Protea
