ments white, with red mid-vein, lanceolate, acuminate, 6 to 8 mm. long: ovary not 
crested.—Western and southern Texas. 
7. A. stellatum Fraser. Scape 1.5 to 2.5 dm. high, slender, bearing an erect 
umbel: outer bulb-coats reddish, with very close linear reticulations: perianth- 
segments broad, acute, mostly rose-color: stamens and style exserted: ovary con- 
spicuously 6-crested.—Northwestern Texas and northward. 
== = Seapes low. 
8. A. bisceptrum Watson. Scapes frequently in pairs: bulbs light-colored, with 
indistinet reticulations: perianth-segments (mostly rose-color), oblong-lanceolate, 
acuminate, slightly exceeding the stamens: alternate filaments with a broad deltoid 
adnate base: crests of ovary narrow, central.—On mountain streams, from the Trin- 
ity to East Humboldt mountains. 
9, A. Palmeri Watson. Habit of the last: bulb coats with a distinct somewhat 
quadrilateral reticulation: scape always solitary: perianth-segments (rose-color) 
6 to 10 mm. long, ovate-lanceolate, acuminate: filaments and crests nearly as in the 
last.—In the Chisos mountains. 
++ ++ Leaf solitary. 
10. A. Nevadense Watson. Scape 2.5 to 7 em. high, almost equaling the nar- 
rowly linear or filiform flat leaf: bulb coats light-colored, with close much distorted 
reticulation: spathe-valves acuminate; pedicels 12 mm. long; perianth white or 
pinkish, with lanceolate segments little exceeding the stamens and style.—Dry 
ridges and foothills, from the Trinity to East Humboldt mountains, 
3. NOTHOSCORDUM Kunth. 
Bulb tunicated, not alliaceous, the ovary-cells several-seeded; oth- 
erwise like Alliwm. 
1. N. striatum (Jacq.) Kunth. Scape 3dm. highor less: bulbsmall, often bulbif- 
erous at base: leaves narrowly linear: flowers few, on slender pedicels: the segments 
narrowly oblong (8 to 12 mm. long): ovules 4 to 7 in each cell. (Allium striatum 
Jacq.)— Moist places, throughout the State. 
4. ANDROSTEPHIUM Torr. 
Seape and linear leaves from a membranaceous or fibrous-coated corm, 
with pale-lilac umbellate flowers, unjointed pedicels, funnelform peri- 
anth (the tube equaling the spreading limb or shorter), united bifid 
filaments upon its throat, sessile beaked subglobose pod, and few to 
several large seeds in each cell. 
1. A. violaceum Torr. ScapeSto 15¢m. high: tlowers 16 to 24 mm. long or more, 
usually exceeding the stout pedicels, the tube nearly as long as the limb; crown 
scarcely shorter than the limb, the lobes exceeding the anthers.—From the Colorado, 
through central Texas to the Trinity. 
5. MILLA Cav. 
Scape from a small membranaceous-coated corm, with the white sal- 
verform perianth greenish outside and with stout green mid-veins and 
narrowly turbinate tube, nearly sessile naked stamens with basifixed 
anthers, and an oblong ovate sessile pod. 
1. M. biflora Cav. Leaves subterete, very rough: scape (5 to 30 cm. high), 
smooth, bearing 1 to 5 nearly equal elongated pedicels (7 to 15 em. long): perianth 
(3 to 5 em. long) with the broadly oblong-lanceolate segments (inner narrower) 
about twice longer than the tube.—E] Paso County.
