 PoiNCIANA, De Candolle. In honour of M. de 

 Poinci, once governor of the Antilles, and a 

 patron of botany. Linn. 10, Or. 1, Nat. 

 Or. Fabaccce. This genus, the Barbadoes 

 Flower-fence, is truly elegant and ornamental. 

 P. pulchlrrima is a spiny plant, growing about 

 twelve feet high, the bruised leaves of which 

 emit an odour resembling Savin. They re- 

 quire a good rich soil, and a strong heat to 

 make them flower well iu our stoves ; cuttings 

 will strike readily in sand. They sometimes 

 produce seed, from which they may also be 

 increased. See Coulteria.

 This is a very elegant genus of plants, all well 

 worthy of being cultivated for ornamenting 

 the pillars or back of the stove. They grow 

 best in a mixture of sandy loam and peat, and
