Trise VIII. Hemerocallidez. Flowers large, on naked jointed pedicels 
with conspicucus bracts, simply racemose upon a leafy stem from a tunicated bulb 
(or fleshy-fibrous roots) : perianth funnel-form, 6-cleft: stamens on the throat; 
anthers versatile : seeds (in our genus) horizontal, flattened, numerous, black. 
23. HesperocaLlis. Perianth white, cleft to below the middle; 
segments several-nerved. Anthers linear. Capsule ovate-oblong, 
deeply lobed. Raceme few-flowered, the stout pedicels jointed at 
the summit. 
Trine IX. Yuccez. Flowers racemose-paniculate upon a stout leafy or 
leafy-bracteate stem from a stout caudex or thick and often branching rootstock ; 
segments distinct: anthers versatile, sagittate: seeds numerous, in 2 rows in 
each cell, horizontal, flattened, black. Leaves numerous and crowded, linear, 
thick and more or less rigid: pedicels jointed at the summit. . 
24. HresperALor. Perianth narrowly cylindric, reddish; segments 
linear, about 7-nerved. Filaments subulate-filiform, smooth ; 
anthers linear-oblong. Style filiform, deciduous; stigma small, 
capitate. Capsule loculicidal, 3-celled. Caudex very short, 
sending up a slender sparingly bracteate flowering stem: leaves 
linear, deeply channelled, with filiferous margins: flowers fas- 
cicled, erect. 
25. Yucca. Perianth campanulate, white or whitish; segments 
ovate-lanceolate, many-nerved. Filaments clavate, often papil- 
lose; anthers small. Style stout and persistent (or none); the 
emarginate stigmas more or less connate into a stigmatic tube. 
Fruit baccate, or capsular and septicidal or loculicidal, incom- 
pletely 6-celled. Rarely acaulescent, usually with a stout woody 
caudex, often tall and tree-like: leaves linear-lanceolate, spines- 
cent at apex: flowers usually solitary and nodding. 
SERIES II. Floral bracts none or foliaceous. Perianth deciduous ; segments 
distinct, net-veined. Stamens hypogynous, or at the very base; anthers more 
or less extrorse. Styles united at least at base, deciduous. Fruit loculici- 
‘ dally dehiscent or berry-like. Seeds turgid, with thin close brown testa. Flowers 
mostly large and showy, solitary or racemose or pseud-umbellate. Pedicels not 
jointed. Leaves with anastomosing veinlets. 
Exceptions. Perianth persistent in L/oydia and Trillium; segments several- 
nerved in Lloydia, Clintonia, Medeola, and Scoliopus. Anthers usually introrse in 
Trillium. Style persistent in Lloydia ; «stigmas sessile and persistent in Calo- 
chortus, Scoliopus,and Trillium. Capsule mostly septicidal in Calochortus. Seeds 
flat and horizontal in most Liliee ; crustaceous in Clintonia. Leaves with trans- 
verse veinlets in Lloydia (1%), Calochortus, Scoliopus, and most Uvulariee. 
Trise X. Lilieze. Flowers terminal or axillary or subumbellate, upon a 
more or less leafy stem from a bulb or coated corm, campanulate or funnel- 
form; segments usually nearly equal and similar, bearing a nectary or gland: 
capsule many-seeded: seeds horizontal or ascending.
