HO MISSOURI BOTANICAL GARDEN. 



cave, shagreen-roughened, narrowly brown-bordered, coarsely flliferous. 

 Flowers very large for the genus, oblong-campanulate, the lanceolate 

 segments about 75 mm. long: style slender, elongated, gradually taper- 

 ing; stigmatic lobes short. Fruit very large (as much as 200 mm. long), 

 mostly conical-ovoid, with adnate calyx-disk and filament bases : seeds 

 7 X 9 to 10 mm - Plates 68-69. 85, f. 4.

This, the first discovered of the western fleshy-fruited 

 Yuccas, differs from the species which have been confounded 

 with it in its prostrate caudex, the crowns of which rarely 

 rise much above the earth, its very large pendent flowers, 

 and its decidedly conical large fruit with the base of the 

 perianth adnate as a conspicuous disk, and the bases of the 

 filaments forming fleshy papillae, as in Y. aloifolia. A 

 note by Dr. Palmer* on the uses made of Y. baccata by 

 the Indians, and many of the published references under 

 this name, may refer to the next species, while the Yucca 

 baccata of the Pacific coast is what is here called Y. 

 Mohavensis.

Arborescent, subsimple, becoming 3 to 5 m. high. Leaves yellowish- 

 green, .5 to 1 m. long, 40 to 50mm. wide, usually rough, concave, coarsely 

 flliferous. Panicle glabrous or occasionally pubescent, the bracts at first 

 often brownish. Flowers mostly more globose and smaller (the perianth 

 segments usually about 40 mm. long). Fruit oblong, not usually as 

 large as in Y. baccata: seeds 5 to 6 X 6 to 8 mm. Plates 70. 71 85
