YUCCA 



with median whitish stripe on the lvs. is var. medio- 

 striata, Planch. Among the numerous varieties and 

 forms into which this, the first-cultivated Yucca, has 

 sported, the following are most worthy: Var. plicata, 

 Carr. Lvs. very glaucous, strongly plicate. G.C. III. 

 T5:304. Rep. Mo. Bot. Gard. 3, pi. 6. Var. recurvifolia, 

 Engelni. ( Y. recurvi- 

 fdlia, Salisb. 1". re- 

 cnrva, Haw. V. pfn- 

 dula, Hort. Has the 

 lvs. less plicate, soon 

 green, gracefully re- 

 curved, occasionally

 marginal threads. Car- 

 olina coast region. Gn.

 p. 433; 1859, p. 488. 

 Variegated forms of 

 this are the following: 

 Var. marginata, Carr. 

 Lvs. yellow-margined; 

 var. variegata, Carr. 

 Lvs. with yellow me- 

 dian band; and var. 

 elegans, Hort. Lvs. 

 with reddish median 

 band. Var. nobilis, Carr. 

 (Y.JSllacdmbei, Bak.). 

 Lvs. glaucous, not pli- 

 cate, less recurved. 

 Var. flexilis, Trel. ( Y. 

 fUxilis, Carr.). Lvs. 

 long, narrow, less than 

 an inch wide, scarcely 

 plicate, glossy green, 

 gracefully recurved, 

 occasionally a little 

 rough on the margin.— 

 Hybrids of Y.gloriosa 

 with both capsular and 

 fleshy - fruited species 

 have been artificially 

 produced in Europe, 

 and are in some European gardens under the names Y. 

 Deleuili, Y. sulcata, Y. Carrierei, Y. Andreana, Y. 

 draectnoides, Y. striatula, Y. Massiliensis, Y. ensi- 

 fera, Y. Imviqata and Y. juncea. R.H. 1886, p. G3; 

 1895, p. 81. For descriptions see R.H. 1893, p. 109. 

 Other hybrids not yet in the trade have more lately 

 been produced by Sprenger, of Naples. 



C. aloifdlia, Linn. Slender simple trunk 10-15 ft. 

 high: lvs. dagger-shaped, 1-2 in. wide, flat, very stiff 

 and pungent, not plicate: panicle compact, close to the 

 lvs.: fls. white, often tinged with green or purple; 

 ovary distinctly stalked. Southeastern U. S. and West 

 Indies. B.M. 1700. — Variegated forms are: Var. margi-
