Yucca? PARVIFLORA (n. sp.): subacaulis ; foliis anguste-linearibus rigidis recurvatis 
margine filamentosis ; pedunculis scapiformibus банк заар. bracteis е basi dilatatis promisse 
acuminatis; pedicellis fasciculatis; sepalis linearibus subconniventibus; stylus filiformibus, 
stigmate integro truncato. Gravelly hills near the mouth of the Pecos; Bigelow. Stony hills 
west of the Nueces, Texas; Wright, (No. 1908). Caudex apparently very short. Leaves 12- 
18 inches long, 4—5 lines wide, conduplicate when dry, very smooth, acute at the tip, but not 
pungent ; the filaments on the margin 1-2 inches long and about as thick as common sewing- 
thread. Scape 8—4 feet long, with distant clasping bracts ; the upper part racemose and some- 
what branching. Pedicels 3-4 together, 6-10 lines long, arising from the axis of a clasping 
bract, erect, a little thickened upward and articulated close to the flower. Perianth white? the 
divisions about three-fourths of an inch long, scarcely 2 lines wide, rather obtuse, ( ‘scarcely ) 
united at the base. Stamens 6, shorter than the perianth ; anthers oblong; bifid at the base. 
Ovary oblong, 3-celled; the cells with numerous horizontal ovules; style a little exserted, 
filiform, triangular and a little enlarged toward the extremity, This differs from all the other 
species of the genus in its elongated filiform style and narrow sepals. The fruit of Mr. Wright's 
specimens in Dr. Gray’s herbarium is unripe. It is subglobose, and about ап inch in diameter. 
As Mr. Wright likens it to a fig, it is doubtless fleshy. 
Yucca PUBERULA, Haw. in Phil. Mag. March 1828, ex Kunth. Enum. 4, p. 272. Y. brevifolia, 
А. Schott, MSS. Valley of the Santa Cruz river, and Sierra del Pajarito, near the monument, 
Sonora, June ; Schott. Stems 6-8 feet high. Leaves mostly іп a terminal crown, about a foot 
long and 5-6 lines wide, concave above, a little rounded underneath, of a thick and firm texture, 
with a few loose threads on the margin, the apex armed with a spine. The persistent retrorsely 
imbricated vestiges of former leaves give the stem a very rough appearance. Scape 2-3 feet 
long, paniculate above, pubescent. Bracts at the base of the branches lanceolate, tapering to 
along point. Flowers apparently white. Sepals broadly elliptical 1} inch long, rather acute. 
Fruit about 23 inches long, and 11 in diameter, pointed with the base of the styles. “This is 
the Sotol of the Sonorians, but not of the Texans along the Rio Grande. It bears large fleshy 
fruits which are edible, and called Datili, probably on account of their shape.’’—Schott. 
Yucca RUPICOLA, Scheele in Linnea, 23, p. 143. Y. tortifolia, Lindh. MSS. Gravelly hills and 
plains, western Texas, New Mexico, and Chihuahua, April-May. (No. 688, 689, and 1,909, 
Wright. No. 109, Fasc. IV, Lindheimer.) Fruit an inch and a half long, dry or nearly so, often 
remarkably constricted near the middle. 
Yucca Baccara (n. sp.): foliis lanceolatis planis crebris margine filamentiferis apice convolutis, 
spina terminali brevi ; floribus campanulatis; fructibus 18 cernuis ovatis baccatis. Раттав, 
Cohahuila; Thurber. High table lands between the Rio Grande and the Gila; Major Emory. 
This is the same species that is noticed inthe Botany of Whipple’s Report as having been found 
at Hurrah Creek, New Mexico, by Dr. Bigelow. According to Dr. Bigelow it is a low species, 
with a subterranean caudex. We have no information as to the length of the scape. The 
flowers appear to form a racemose panicle. They are larger than in any other species of Yucca 
here noticed ; the sepals being 24-3 inches long, tapering to each end and 6-7 lines wide in the 
middie. .The fruit is the size of a large fig, with a sweet edible pulp. Near Monterey, Cali- 
fornia, Dr. Parry collected the leaves of аг yucca resembling those of this species, except in 
being smaller. On the plains of western Texas; near the Limpio, and in the vicinity of Presidio 
del Norte, Dr. Purse found a yucca 10-15 feet high, with leaves almost exactly like those of
