298 IXIACEAE 
curved : spathes 14-19 mm. long, sometimes slightly purplish: bracts firm-herbaceous, 
conspicuously hyaline-margined, nearly equal, somewhat keeled, acuminate : interior scales 
exserted at maturity : flowers 8-12 together: perianth violet-blue, 12 mm. long or more : 
capsules 4-6 mm. high, on spreading or recurved pedicels : seeds rugulose, becoming fully 
1 mm. in diameter. 
In dry sandy soil, peninsular Florida. Early spring. 
14. Sisyrinchium fuscatum Bicknell. Plants thinly tufted, rather stiff, 15-50 cm. 
high, more or less fibrose at base, dull green and glaucescent, drying dark. Leaves firmly 
erect, becoming flexuous, long and slender; blades 0.5-2.5 mm. wide, close striate, the 
edges smooth or roughened : scapes straight and slender, longer than the leaves, 0.75-2 
mm. wide, narrowly winged: bracteal leaf narrow, erect, shorter than the peduncles: pe- 
duncles 2, approximate, subterete, short and erect, 2-6 cm. long: spathes narrow, 1.5-1.8 
em. long, the subequal bracts firmly herbaceous, striate, cuspidate-acuminate: interior 
scales much shorter than the bracts: flowers blue, on erect exserted pedicels : perianth 
about 10 mm. long, the narrow sepals and petals prominently veined : capsules 2.5-4 mm. 
high, broadly subglobose, drying dark. 
In sandy soil, western Florida to Mississippi. Spring. 
15. Sisyrinchium incrustatum Bicknell. Plants thinly tufted, 2.5-5 dm. tall, 
coarsely fibrose at the base, dull green and glaucescent, drying dark. Leaveserect ; blades 
1.5-3.5 mm. wide, aculeate-tipped, rather thin but firm, striate, harshly rugulose-sca- 
brous to densely incrustate-roughened with pale papillae, the edges ciliolate-serrulate : 
scapes often sinuously curved, 1.5-3 mm. wide, roughened like the leaves; nodes 1-2, the 
lower one bearing an often much elongated bracteal leaf and 2-3 peduncles, the upper one 
terminating an outcurved prolongation of the scape 4-9 cm. long, with a shorter bracteal 
leaf and peduncle: spathes 1.5-2.5 cm. long, the nearly equal bracts acute to slenderly at- 
tenuate : interior scales shorter than the bracts: perianth violet-blue, about 8 mm. long: 
capsules subglobose, dark, 3-4 mm. in diameter, on slightly exserted nearly erect pedicels : 
seeds finely pitted, 1-1.5 mm. in diameter. 
In moist sandy soil or open grassy woods, North Carolina. Summer. 
16. Sisyrinchium rüfipes Bicknell. Plants thinly tufted, often very slender, 1.5-3 
dm. tall, with rufous or brown fibers at the base, rather bright green and glaucescent, 
partly turning a dull brownish green. Leaves becoming flexuous ; blades 1-2.5 mm. wide, 
often granular-scabrous between the close nerves, the margins finely sharp-serrulate : scapes 
about as tall as the leaves, slender and often flexuous, about 1 mm. wide, narrowly mar- 
gined, the edges closely ciliolate-serrulate, bearing an erect slender bracteal leaf subtend- 
ing a cluster of 2-3 short-peduncled or merely stipitate spathes and sometimes also a short 
branch : spathes about 12 mm. long, the bracts somewhat divergent: flowers 2-5, on hair- 
like flexuous pedicels: perianth blue, about 8 mm. long: anthers relatively large: cap- 
sules about 3 mm. high. 
On sand hills, North Carolina to Georgia. Early spring. 
17. Sisyrinchium fibrdsum Bicknell. Plants loosely tufted, 2-3 dm. tall, fibrous- 
coated at the base, pale and glaucescent, often yellowish green. Leaves firm ; blades some- 
what striate-nerved, mostly 2-3 mm. wide, or some of them even 5 mm. wide, the edges 
usually serrulate : scapes longer than the leaves, 2-3 mm. wide, broadly winged, the edges 
mostly serrulate or even ciliolate; nodes 1-2, each furnished with a foliaceous bracteal leaf 
which subtends 2 or 3 more or less diverging peduncles: peduncles 4-8 em. long: spathes 
15-20 mm. long, the bracts nearly equal, varying from herbaceous attenuate to scarious-obtuse 
and mucronulate : interior scales about 4 the length of the bracts: flowers on delicate loosely 
erect slightly exserted pedicels: perianth pale violet-blue, 8-10 mm. long: staminal column 
4-5 mm. high: capsules pale and thick-walled, broadly ovoid, 3-4 mm. high: seeds rugu- 
lose, 1 mm. in diameter. [S. Carolinianum Bicknell, not Klatt. ] 
In woods or fields, North Carolina to Florida and Mississippi. Spring. 
18. Sisyrinchium tértum Bicknell. Plants thinly tufted, 1.5-3 dm. tall, pale and 
glaucous, coarsely fibrous at the base. Leaves erect, the longer ones nearly equalling the 
scapes; blades firm, 1.5-3 mm. wide, finally close-striate, faintly vermiculate-rugulose be- 
tween the nerves, the edges smooth or obscurely roughened : scapes usually one to four 
times spirally twisted, as wide as the leaf-blades, wing-flattened, usually with but one node: 
bracteal leaf short, broad-based, equalling the 2 peduncles or shorter: spathes 10-16 mm. 
long, usually abruptly broader and thicker than the peduncles, becoming 3 mm. wide, 
the bracts nearly equal, rather thin and membranous: interior scales shorter than the bracts : 
flowers on loosely erect finally exserted pedicels: perianth pale blue, 8-10 mm. long: 
staminal column short, 2-4 mm. high. 
In sandy soil, Florida and Mississippi. Early spring.
