OF ARTS AND SCIENCES. oS 
leaves rarely extend at all above ground, the bracts are never 
elongated, and the filaments are without cusps or teeth, the bases 
united into an adnate disk (except in A. tricoccum). 
2. NorHoscorpum. Flowers greenish or yellowish white. Cap- 
sule oblong-obovate, somewhat lobed, obtuse, with the style ob- 
scurely jointed on the summit; cells several-ovuled. Filaments 
filiform, distinct, adnate at base. Bracts 2. Leaves several. 
Bulb tunicated: not alliaceous. 
Tripe ll. Millez. Bracts several, not spathaceous, distinct: capsule not 
lobed (or slightly so), acute, and beaked by the mostly stout (at length split- 
ting) style: seeds few to several in each cell, angular: perianth-segments more 
or less united or distinct, 1-nerved or rarely closely 2-3-nerved: scape from a 
membranous- or fibrous-coated corm. 
* Perianth parted to the base or nearly so; segments spreading, closely 
2-3-nerved: stamens in one row atthe base; anthers versatile : capsule obovate 
or subglobose, sessile or nearly so; cells several-seeded. 
3. Muitia. Flowers greenish-white. Filaments filiform, naked, 
adnate at base. Pedicels not jointed. Leaves several. 
4, Broomerta. Flowers yellow, on jointed pedicels. Filaments 
elongated, free, surrounded at base by a somewhat cup-shaped 
and winged appendage. Leaf solitary. 
* * Perianth evidently gamophyllous, with the stamens on the throat. 
+ Perianth funnel-form; segments l-nerved (very rarely 2-3-nerved in 
Brodiea): pedicels jointed (except in Androstephium).

5. Bropi#a. Perianth more or less narrowly funnel-form, not con- 
tracted at the throat, nor saccate or but very slightly so at base, 
blue-purple or white or yellow. Stamens 6, in one or two rows 
with winged or naked filaments, or 3 and alternate with as many 
staminodia. Capsule ovate to oblong. 
6. STROPHOLIRION. Flowers rose-colored, the short broadly turbinate 
tube 6-saccate, contracted at the throat, about equalling the 
spreading limb. Stamens 3, alternate with 3 ligulate staminodia ; 
filaments winged ; anthers basifixed. Capsule nearly sessile, ovate, 
acuminate. 
7. Brevoortia. Perianth-tube broad, 6-saccate at base, deep scarlet, 
several times longer than the short erect or reflexed yellowish limb. 
Stamens 3, alternate with 3 broad truncate staminodia; anthers 
basifixed, nearly sessile. Capsule long-stipitate, ovate, acuminate. 
8. ANDROSTEPHIUM. Flowers pale lilac, the cylindrical tube about 
equalling or shorter than the somewhat spreading limb. Sta- 
mens 6,in one row; the filaments united to form an erect tubular
