296 NOTES ON THE GENUS YUCCA. 
but slender and weak point, and numerous thin deciduous threads. Scape 4-6 feet high, stout, greenish bronze, 
almost covered with large foliaceous bracts, the lower 9~12, upper 4-6 inches long, tapering upwards ; panicle con- 
tracted, scarcely half as long as the flowerless part of the scape, rough, uneven, or somewhat pubescent. Flowers white 
with greenish, about 3 inches wide; pistil 16 lines, stamens half as long, elongated stigmas at last divaricate at tip. 
Capsule 14-2 inches long with a short cusp, rarely constricted. Seeds 8 min. wide. The rarest of the South Carolina 
forms, and not seen from anywhere else ; flowers later than the others, in the second half of June. 
Var. ? levigata is well characterized by its very long (30-40 inches, 10-15 lines wide), deep green,smooth, [54] 
thickish, very sharp pointed leaves, only 25-50 in number ; lower third attenuated into a narrow stalk, lea 
therefore soon decumbent; epidermis cells 3 times as long as wide. Scape 8-10 feet high, smooth, purple below with 
lance-shaped bracts 6-9 inches long ; panicle half as long as peduncular portion, contracted, with comparatively few, 
sometimes slightly pubescent branches. Flowers often in pairs, smaller than in last, 23-3 inches wide, white with 
e tinge, of a strong almost disagreeable odor, which was not noticed in other varieties ; eee divided to the 
base, deeply bilobed. Capsules 14-2 inches long ; short pointed ; seeds 83-9 mm. wide. This is the most common 
species between Charleston and Hilton Head, on the sandy coast, but is also found: on the clayey soil up the rivers ; it 
probably extends down the coast to Florida, as I have seen a specimen from Tampa Bay, — flowers about 2 weeks 
after the first and as long before the last form. A transition form between this and the regular Y. filamentosa is culti- 
vated in the Missouri Botanical Garden, with shorter, weaker-pointed leaves, lanciform bracts, and constricted capsules.

Califo ornia, on dry rocky hills, rare north of San Francisco, abundant from Monterey to San Diego, eastward to 
the Cajon Pass and into Northwestern Arizona ; flowers in April. — Trunk none or short, sometimes prostrate between 
rocks, stoloniferous ; leaves 10-20 inches long, 4-6 lines wide, concave only near the stout point ; scape 4-12 feet high, 
together with the lower part of the panicle itself, beset with bracts 6-9 inches long, consisting of a broad whitish hase 
terminating in a short rigid leaf. Flowers greenish white, spreading 2 to 4 inches ; segments 14-2} inches long, 5-12 
lines wide, outer much narrower than inner ones ; anthers 1-14 lines across ; pistil 4-8 lines long ; style proper slender, 
as long as or much shorter than the ovary ; trilo hood-like stigma 3 times as thick as style and longer than thick. 
Capsule less than 1 to nearly 2 inches long, ae rough ; secondary rege goke incomplete at both ends, divided 
and often rent by the opening of the caps sale seeds 64-8 or 9 mm. in diameter, with a very narrow margin. — Most 
of the specimens and numerous notes have been communicated by Prof. W. HL Brewer of the California State 
Survey.
