SBAC^NA (female dragon; the dried juice supposed 

 to resemble dragon's blood). ZdlicLeecr. A genus of 

 tropical plants of which but few are in cultivation. They 

 are all woody, often arborescent, with sword-shaped or 

 broad lvs., mostly crowded at the summit of the stem: 

 fls. clustered in panicles or heads, greenish white or yel- 

 lowish ; perianth salver-form or companulate ; lobes 

 spreading; stamens 6: fr. a 3-ceUed berry. Differs from 

 Cordyline in having larger fls., and solitary instead of 

 many ovules in each cell of the ovary. All ornamental 

 stove plants, frequently with variegated lvs. See Baker, 

 Journ. Linn. Soc, vol. 14, for a monograph of the genus. 

 Draecena Draco, of the Canaries, is the Dragon Tree. It 

 reaches a height of 30-60 ft., branching when of great 

 age. The Dragon Tree of Teneriffe, famous for centuries, 

 is 70 ft. high, and one of the oldest of known trees.

 aie : alba-ma rginat a, argenteo-striata, DeSmetiana, 

 EUsahethim, Frederica, Mendersoni, imperator, Sal-
