Douglasia. Named by Dr. Lindley, some 

 , years ago, in compliment to Mr. Douglas, 

 whose zeal in collecting seeds and plants, and 

 whose untimely end have richly earned for him 

 a niche in the long gallery of departed science. 

 Linn. 5, Or. 1, Nat. Or. Primulaceoe. This 

 is a very beautiful, but scarce, little plant, 

 growing pretty freely in peat and sand, and 

 ripening its seed in small quantity. Mr. 

 Douglas transmitted the seed, from which this 

 interesting plant was raised, from the Eocky 

 Mountains, where he first found it among the 

 snow, and afterwards from California,

Draba, De Candolle. From drabe, acrid, biting ; 

 taste of the leaves. Linn. 15, Nat. Or. Bras- 

 sicacece. Some of the species of this genus are 

 very pretty, being well adapted for ornament- 

 ing rock-wovk, or growing in pots, among 

 other alpine plants. A mixture of loam and 

 peat suits them best, and they increase with 

 facility, either by dividing at the roots, or by 

 seeds. Synonymes: 1, D. aizoldes ; 2, D. in-

DracAna, Linn. From drakaina, a female 

 dragon ; the inspissated juice becomes a pow- 

 der, like the dragon's-blood. Linn. 6, Or. 1, 

 Nat. Or. Lili&cece. Very ornamental trees, 

 well worthy of being cultivated iu every col- 

 lection of stove plants. They thrive well in a 

 light, loamy soil ; large cuttings root freely by 

 being stuck in the tan, provided there be a 

 strong heat. In Java, the root of D. ternii- 

 nalis is considered a valuable medicine in dy- 

 senteric affections. The substance called Gum 

 Dragon, formerly used in medicine, is the 

 juice of D. Drhco. . Synonymes : 1, spiedta,
