faintly pitted or almost smooth.

31. Sisyrinchium Atlanticum Bicknell. Plants tufted, pale and glaucous, 2-6 dm. 
tall. Leaves commonly much shorter than the scapes, firm; blades like the scapes mostly 
1 mm. wide or less and smooth-edged : scapes wiry and narrowly firm-margined : nodes 1 
or 2 bearing narrow bracteal leaves and usually two slender peduncles : spathes often pur- 
plish, 10-16 mm. long, the subequal bracts thin, the outer one acute, the inner mostly 
scarious-obtuse, longer than the interior scales : perianth violet-blue, 8-10 mm. long: cap- 
sules oblong to subglobose, dark, thick-walled, 2-4 mm. high, on erect little exserted pedi- 
cels : seeds numerous, 0.5-1 mm. in diameter, finely wrinkled-pitted to nearly smooth. 
In salt marshes or in sandy soil, mostly near the coast, Maine to Florida. 
32. Sisyrinchium fléxile Dicknell. Plantstall and very slender, becoming 5 dm. tall or 
more, pale green but scarcely glaucous. Leaves long, the longer ones equalling the scapes, 
stiff, becoming flexuous ; blades about 1.5 mm. wide, closely few-striate, very smooth, the 
tips finally hardened: scapes flexuous, subterete and narrowly firm-margined : nodes 1 or 
2, bearing narrow bracteal leaves and nearly terete peduncles 3-7 cm. long, mostly in pairs: 
spathes 1.5 cm. long or more, narrow, subterete at the base, the stiff, subequal bracts closely 
striate, their tips acute or narrowly scarious-obtuse : capsules brown, rather thick-walled, 
broadly oblong, 4-6 mm. high on erect somewhat exserted pedicels: seeds numerous, 0.5-1 
mm. in diameter, alveolate. 
Along the coast, Mississippi. Spring. 
33. Sisyrinchium violàceum Bicknell. Plants light green, drying yellowish and 
brownish, the roots rather thick. Leaves erect or firmly ascending, mostly 4 the height of 
the scapes or less ; blades 1-2.5 mm. wide, strongly nerved: scapes 1.5-2.0 dm. high or 
finally 3.5 dm. high, 1-2 mm. wide, stiff, narrowly firm-margined, the edges smooth : 
peduncles terminal, 2-3, unequal, 4-8 cm. long, the bracteal leaf short and stiffly erect: 
spathes 1.5-3.0 cm. long, the bracts subequal, firmly nerved and finely puncticulate, acute 
or the inner one obtuse : flowers pale violet, rather large, on pedicels subequal with the 
bracts : perianth 1-1.5 em. long: staminal column 5 mm. high or more: capsules dark, 
thick-walled, ovoid-subglobose, 2-3 mm. high: seeds few, 1 mm. in diameter or more, ru- 
gulose-pitted. 
In woods, Walton County, Florida. Summer. 
34. Sisyrinchium nànum Bicknell. Plants low and stiff, 1.2 dm. tall or more, pale 
and glaucous, not fibrose at the base. Leaves sometimes equalling the scapes; blades 1-2 
mm. wide, close-striate: scapes stiff. with firm narrow margins, the edges smooth: 
peduncles one or more, short: spathes about 1.5 cm. long, the bracts closely striate, the 
outer bract acute, sometimes shorter than the scarious-obtuse inner one : flowers on slightly 
exserted pedicels : perianth bright violet-blue, about 10 mm. long : staminal column 4 mm. 
high or less. 
Along the coast, Mississippi. Late spring and early summer. 
35. Sisyrinchium Tràcyi Bicknell. Plantsslightly glaucescent, discoloring somewhat 
when dry, rather stout, stiff, 3.5-7 dm. high. Leaves j the height of the plant or more ; 
blades 1-3 mm. wide, close-striate: scapes rigid, often curved, narrowly firm-margined, 
like the leaves very smooth and as wide: inflorescence stiff and often contracted, from 2 
nodes, the lower one often bearing 1 or 2 short branches: peduncles mostly in clusters of 
3’s—4’s, slender, stiff, approximate, the upper 3-5 cm. long: lower bracteal leaf elongated : 
bracts of the spathe strongly close-striate, subequal, 15-22 mm. long, the outer one often 
abruptly short-acuminate, the inner mostly scarious-obtuse: flowers on scarcely exserted 
pedicels: perianth violet-blue, 10-12 mm. long, with long-aristulate sepals and petals: 
staminal column 5-6 cm. high. 
Insandy soil, southern Mississippi. Spring. 
. 36. Sisyrinchium scoparium Bicknell. Plants pale and glaucous, in close tufts 
1.5-5 dm. high. Leaves very slender, equalling the shorter scapes ; blades 1-1.75 mm. 
wide, the edges mostly smooth : scapes narrowly wing-margined: inflorescence sometimes 
scant but often appearing dense from the numerous clustered scapes, mostly arising from 2 
nodes each bearing a short bracteal leaf and 2-3 somewhat diverging usually short pedun- 
cles: spathes 1.2-1.8 cm. long, the subequal bracts striate-nerved, acuminate : perianth 
violet-blue, 8-10 mm. long: staminal column about 4 mm. high: capsules clustered on 
pedicels about equal with the bracts, dark, thick-walled, remaining slightly puberulent at 
maturity, 2-5 mm. high: seeds 1 mm. in diameter, finely pitted. 
On or near the coast, Mississippi. Spring.
