 paler yellow. 



10. cuspidata, Bieb. Cespitose: Ivs. linear-acute: 

 scape villous or woolly, the fruiting raceme short; 

 petals yellow, twice exceeding the calyx; anthers equal- 

 ing the petals: fr. lanceolate and somewhat turgid, 

 setulose. Asia Minor. Aspect of D. aizoides, but 

 scape shorter and pod somewhat inflated. 



11. olympica, Sibth. (D. bruniaefdlia, Stev.). Densely 

 and broadly cespitose, about 4 in. high: Ivs. narrowly

offered abroad, is described as "very close, compact tufts, white 

 fls." D. tfrna, Linn. WHITLOW-GRASS. A winter annual, widely 

 naturalized from Eu., with white fls., bifid petals, oblong-obovate 

 to oblanceolate rosulate Ivs., slender scapes 2-6 in., and glabrous

DRACflJNA (female dragon; the dried juice supposed 

 to resemble dragon's blood). Liliaceae. DRACENA. 

 Ornamental hothouse or stove plants, frequently with 

 variegated leaves. 



Often arborescent, with sword-shaped or broad Ivs. 

 mostly crowded at the summit of the st. : fls. clustered 

 in panicles or heads, greenish -white or yellowish; 

 perianth salver-form or campanulate; lobes 6, spread- 

 ing; stamens 6: fr. a 3-celled berry. Differs from Cordy- 

 line in having larger fls., and solitary instead of many 

 ovules in each cell of the ovary. About 40 tropical 

 woody plants, a few being in cult. See Baker, Journ. 

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



Dracsena Draco, of the Canaries, is the dragon tree. 

 It reaches a height of 30 to 60 feet, branching when of 

 great age. The dragon tree of Teneriffe, famous for 

 centuries, was 70 feet high, and one of the oldest of 

 known trees. See Cordyline for other names not found 

 in this article; also for culture. 



The following key to the cultivated species of both 

 Dracsna and Cordyline is based upon the Ivs.
