BOTANY. 147 
Downieville, California. Colonel Frémont found it on Antelope Creek, one of the tributaries of 
the Upper Sacramento , and it is No. 2004 of Hartweg's California collection. If the character 
given above prove constant, this fine lily must be considered a distinct species from L. Canadense. 
YUCCA ALOIFOLIA, Linn. Spec. p. 457; Kunth, Enum. 4, p. 270? Near a mountain arroyo, 
Williams’ River. **Plant 15 feet high." The specimens are with leaves only. Also found at 
Cajon Pass, Sierra Nevada, in March, with ripe capsules of the preceding season. The same . 
plant, or one very much resembling it, was found by Mr. Wright in New Mexico, and is his 
No. 1909. The flowers are very large and white. S 
Yucca Draconis, Linn. l. c.; Kunth, Le Var. ARBORESCENS: foliis lineari-lanceolatis rigidis, 
margine serrulato-scabris. Sandy and gravelly plains west of the Colorado, California. Dr. 
Bigelow states that this species attains the height of 30 feet, with a diameter of 18 or 24 inches. 
He found “ whole forests" of this tree on the Mohave creek. The leaves are flat, about 34 
inches long, and from } to 4 an inch wide, thick, convex below, flat or concave above, pointed 
with a strong spike, the broad flat base about half as long as the upper rigid and narrower 
portion. For want of more complete specimens we cannot be certain of the species, 
Yucca ANGUSTIFOLIA, Pursh, Fl. 1, p. 227; Nutt. Gen. 1, p. 218. Plains of Northern New 
Mexico. Leaves only: these are 12-15 inches long, and scarcely more than one-fourth of an 
inch wide, tapering upward, and ending in a strong sharp spine, thick and rigid, filamentous 
on the margin, along which is a narrow white line. 
Dr. Bigelow collected in New Mexico (near Hurrah creek) specimens of a Yucca which seems 
to be undescribed. The leaves are a foot or more in length, and nearly an inch wide, very 
thick, entire, abruptly pointed with a short blunt spine, and furnished on the margin (especially 
towards the base and summit) with coarse tortuous fibres, tapering a little towards the base, 
and then dilated into a short sheathing base, which is of a brownish-red color. Flowers not 
seen. Fruit racemose, drooping, oval, as large as a hen's egg, pointed with the thick per- 
sistent style. Itis of a soft fleshy consistence, and has a sweet taste. Endocarp thin and 
almost membranaceous, 3-celled, each cell partially divided into two others, Seeds piled hori- 
zontally in the cells, somewhat semi-circular, with thick edges, flat, black, wrinkled. Embryo 
straight, cylindrical, nearly the length of the seed; the albumen fleshy and somewhat indurated, 
a transverse section (parallel with the flat surfaces) appearing ruminated. The fleshy fruit, on 
account of the large quantity of grape sugar it contains, can be dried without decomposition, so 
as to have about the same consistence as a dry fig. 
Still another species was found in rocky places near Pecan creek, a tributary of the Cana- 
dian. The leaves are a foot long, and three-fourths of an inch wide, flat and rather thin; the 
margin thin, sparingly furnished with very fine threads. No flowers were obtained. The fruit 
is in an elongated raceme. "The pods are about two inches long, and more than an inch in 
diameter, erect and pedicellate; the mesocarp thin and somewhat fleshy, when dry a little 
papillose; cells divided by an accessory septum into 2 locelli. Seeds flat, smooth, and thin, 
black ; the embryo two-thirds the length of the albumen. We need more complete specimens 
in order to determine whether the species is described. 
Camassta ESCULENTA, Lindl. Bot. Mag. t. 1486; Kunth, Enum. 4, p. 341. Phalangium Qua- 
mash, Pursh, Fl. 1, p. 226. Marshes, Punta de los Reyes, California; April 17. The Scilla 
esculenta, Gawl. in Bot. Mag. t. 1574, (Phalangium esculentum, Nutt.) is certainly a congener 
of this plant, and not a Scilla. In our specimens of the C. esculenta, Lindl., we do not find 
the five upper sepals ascending, and the lowest one deflexed ; but it is difficult to decide on such 
characters in dried specimens. In other respects the Northwest Coast species is so near the 
eastern one that they can be distinguished only by the considerably larger flowers, usually 
broader leaves, and more rfumerous ovules of the former. We find from 16-to 18 ovules in each 
cell of the ovary of C. esculenta, while in the other, which may be called C. Fraseri, the cells 
are only 8-ovuled. The genus Scilla has the sepals one-nerved, somewhat campanulate-con-
