TRILLIACEAE 275 
2. NOLINA Michx. 
Coarse herbs, with woody caudices. Leaves crowded on the caudex : blades rigid, 
narrow, elongated, curved, entire or serrulate, keeled. Flowering stems often widely 
branching. Flowers polygamo-dioecious, in open panicles. Perianth white, withering- 
persistent : sepals and petals distinct, I-nerved. Stamens 6, reduced to staminodia in the 
pistillate flowers : filaments thickish, shorter than the perianth. Ovary 3-celled, abortive 
in staminate flowers : style obsolete or very short during anthesis. Ovules 2 in each cavity, 
erect. Capsule dry, 3-winged, tardily and irregularly opening. Seeds often solitary, 
thick. 
Capsules fully as long as broad, not notched at the ends, or barely so at the apex. 1. N. Georgiana. 
Capsules manifestly broader than long, notched at the ends. 
Capsules 10 mm. broad: perianth about 10 mm. broad : Floridian species. 2. N. Brittoniana. 
Capsules 5 mm. broad: perianth 4-5 mm. broad : Texano-New Mexican species. 3. N. Lindheimeriana, 
1. Nolina Georgiàna Michx.  Flowering stem scape-like, 5-15 dm. tall: leaves 
numerous ; blades linear, rigid, 2-7 dm. long, widely spreading, those of the flowering 
stem much reduced, nearly erect: panicle more or less elongated, rather loosely flowered : 
perianth 4-5 mm. broad : sepals and petals oblong to oblong-lanceolate : capsules suborbic- 
ular or obovoid-orbicular, 6-8 mm. long, 3-winged, barely notched at the apex. 
In dry pine lands, South Carolina, Georgia and Florida. Spring. 
2. Nolina Brittoniàna Nash. Flowering stem 10-20 dm. tall: leaves 40-70, form- 
ing a dense mat about the base of the plant ; blades linear, strap-like, recurved and pros- 
trate, 1-2 m. long, scabrous-margined, attenuate to a slender apex: panicle oblong or ovoid 
in outline: perianth nearly 10 mm. broad : sepals and petals elliptic or elliptic-obovate, 
glandular at the apex : capsules broader than high, 10 mm. broad, on recurved pedicels, 
notched at the base and the apex. 
In dry pine lands, Florida. Spring. 
3. Nolina Lindheimeriàna (Scheele) S. Wats. Flowering stem 10-18 dm. tall, often 
proliferously branched : leaves numerous, narrowly linear, 3-9 dm. or 15 dm. long, thin- 
nish, serrulate, more or less strongly concave: perianth 4-5 mm. broad’: sepals and petals 
oblong-lanceolate, obtusish : capsules 5 mm. broad, much broader than long, notched at 
both ends. 
In stony places, Texas and New Mexico. Spring. 
3. DASYLIRION Zucc. 
Coarse herbs, with woody caudices. Leaves numerous, crowded on the caudex : blades 
narrow and elongated, rigid, spiny-margined. Flowering stems narrowly branched above. 
Flowers dioecious, in close narrow panicles. Perianth white, withering-persistent : sepals 
and petals distinct. Stamens 6, reduced to staminodia in pistillate flowers: filaments 
thickish, longer than the sepals and petals. Ovary l-celled : stigmas 3. Ovules 3, erect. 
Fruit dry-leathery, 3-winged, indehiscent or nearly so. Seed solitary. 
1. Dasylirion Texànum Scheele. Caudex 1-4 dm. long, densely leafy: flowerin 
stem 20-35 dm. tall: leaves spreading; blades linear, 5-12 cm. long, attenuate, arme 
with hooked spines and denticulate between them: panicle narrow, 5-9: dm. long, con- 
spicnously bracted : bracts ovate or ovate-lanceolate, acuminate, membranous, often sur- 
passing the branches of the panicle during anthesis: perianth 2 mm. long ; sepals ovate, 
pe toothed ; petals narrower, more nearly entire: capsules oval or ellptic, 6-7 mm. 
ong. 
Pin stony soil or on prairies, Texas. Spring and summer. 
FAMILY 7. TRILLIÀCEAE Lindl. TRILLIUM FAMILY. 
Perennial caulescent or scapose herbs, with rootstocks, and rather fleshy tis- 
sues. Leaves in a whorl about the middle of the stem, or basal and wanting on 
the mature plant. Bracts in a whorl subtending the inflorescénce at the top of 
the peduncle or scape, usually leaf-like. Flowers perfect, solitary, or in terminal 
umbel-like clusters. Perianth of 3 distinct sepals and 3 petals. Androecium of 
6 short stamens. Anthers 2-celled. Gynoecium of 3 united carpels. Ovary 
3-celled. Stigmas 3. Ovules several in each cavity. Fruit a 3-celled, 3-lobed 
or 3-angled berry.
