300 IXIACEAE 
25. Sisyrinchium tenéllum Bicknell. Plants loosely tufted, 1.5-3 dm. tall, dull 
green, drying dark. Leaves usually openly erect ; blades soft, very thin, 1-3 mm. or even 
4 mm. wide, distinctly few-nerved, mostly smooth-edged : scapes as long as the leaves or 
longer, weakly erect, 1—3.5 mm. wide, mostly with broad thin wings, usually with a single 
node: bracteal leaf erect, usually long and narrow, mostly surpassing the 2 slender pedun- 
cles: peduncles 3-12 cm. long: spathes green, narrow, often deflected, the bracts membra- 
nous, weakly or obscurely few-nerved, slenderly attenuate and very acute, the outer one 
usually somewhat prolonged, 12-25 mm. long: interior scales 3 the length of the spathes 
or less: flowers 3-5: perianth violet-blue, 5-8 mm. long: capsules 1.5-3 mm. high, on 
capillary exserted pedicels : seeds 2-3 in each cavity, rough, 0.75 mm. in diameter. 
In moist soil, Georgia and Alabama. Late spring. 
26. Sisyrinchium dichétomum Bicknell. Plants yellowish green and glaucescent, 
not drying dark, in thin tufts 3-4 dm. high. Leaves half the height of the plant or more, 
blades 2-6 mm. wide, thin but firm, openly nerved, the edges serrulate to smooth : scapes 
broadly thin-winged, more or less dichotomously branched mostly above the middle, from 
2-4 successive nodes: bracteal leaves prominent: lower peduncles sometimes over 10 cm. 
long, the uppermost only 3-5 cm. long, often curved : spathes green, small and narrow, the 
inner bract 8-15 mm. long, the outer one mostly surpassing it, both thin and slender- 
tipped: perianth very small, white, about 5 mm. long: staminal column 2-3 mm. high : 
capsules pale, thin-walled, subglobose, about 3 mm. high, on slender flexuously exserted 
pedicels : seeds only 1-2 in each cavity, large, 1.5-2 mm. in diameter, becoming smooth or 
nearly so. 
In woods, Rutherford County, North Carolina. Spring. 
27. Sisyrinchium flagéllum Bicknell. Plants very slender and flexuous, 1-3.2 dm. 
high, slightly glaucescent, drying dark. Leaves as long as the scapes or shorter ; blades 
narrow and flexuous, 0.5-3 mm. wide, few-striate, smooth-edged : scapes 0.75-1.5 mm. 
mm. wide, narrowly margined, smooth-edged, often flexuous and geniculate at the nodes: 
nodes 1-2, when two remote, supporting narrow bracteal leaves and 1-3 very slender 
peduncles 5-12 cm. long: spathes often deflected, 1.5-2 cm. long, the bracts subequal or 
the inner one longer, and often scarious-margined to the apex, the outer one narrowly 
acuminate: interior scales much shorter than the bracts: capsules on erect slightly ex- 
serted pedicels, subglobose, dark, about 4 mm. high : seeds globose, finely alveolate, about 
1 mm. in diameter. 
In sand, southern and western peninsular Florida. Alsoin Cuba. Late winter and early spring. 
28. Sisyrinchium Miamiénse Bicknell. Plants dull green and glaucescent, drying 
dark, 2 dm. tall or more. Leaves about $ the height of the plant; blades 1-1.5 mm. 
wide, striate-nerved, serrulate : scapes of the width of the leaves, wing-margined, den- 
ticulate-serrulate, bearing 2-3 erect peduncles at the top and sometimes an ascending 
branch lower down: peduncles 3-7 cm. long: spathes 1.3-1.5 em. long, the outer bracts 
stiflly acute, slightly longer than the scarious-obtuse inner one: perianth blue, medium- 
sized : capsules on exserted pedicels, dark, obovoid, 3-5 mm. high: seeds subglobose, 
1-1.25 mm. in diameter, faintly rugulose-pitted. 
In sand, eastern peninsular Florida. Early spring. 
29. Sisyrinchium longifdlium Bicknell. Plants tall and slender, in thin erect tufts 
5-8 dm. high, yellowish green and glaucescent. Roots thickened and clustered : leaves very 
long, about equalling the scapes, erect, becoming flexuous; blades 1.5-2.5 mm. wide, thick- 
ish, closely striate-nerved, mostly smooth-edged, attenuate to the subterete apex, 1.5-2.5 
mm. wide: scapes narrowly firm-margined, with 1 or 2 nodes high up, each supporting a 
short stiff bracteal leaf and a cluster of 3-5 slender, unequal peduncles 5-10 cm. long: 
spathes narrow, 18-22 mm. long, the bracts subequal, stiffly attenuate, very acute : interior 
scales crowded, sometimes exceeding the bracts: pedicels slightly exserted: perianth very 
(pe blue, 12 mm. long, or more: capsules light brown, thin-walled, subglobose, 5-6 mm. 
uigh, the valves developing lateral nerves. 
Insand, Manatee, Florida. Spring. 
30. Sisyrinchium corymbósum Bicknell. Plants 3-7.5 dm. tall, in scant tufts, pale 
dull green and glaucescent, the roots coarse and woody. Leaves stiff and thickish, 3—4 
dm. long ; blades striate-nerved, 1.5-3 mm. wide, mostly smooth-edged : scapes 1.5-4 mm. 
wide, firmly wing-margined, stiffly long-branched above into an erectly subcorymbose 
several times compound inflorescence or the inflorescence scant and little branched in weak 
plants : bracteal leaves often purplish, the upper ones reduced : branches and slender pe- 
duneles 7-14 em. long: spathes small, 12-15 mm. long, the subequal bracts thin and mem- 
branous, delicately close-nerved, acute or subulate : interior scales much shorter than the 
bracts : flowers numerous on exserted pedicels: perianth blue, 8-12 mm. long: capsules
