IXIACEAE 299 
19. Sisyrinchium Floridanum Bicknell. Plants tufted, 2.5-5 dm. tall, densely fibril- 
lose at the base, dull green and glaucescent. Leaves numerous, often equalling the scapes, 
becoming flexuous, thickish ; blades usually 2-3 mm. wide, attenuate to the slender nearly 
terete apex, smooth-edged : scapes narrowly firm margined, 2-3 mm. wide, smooth-edged : 
bracteal leaf shorter than the 2 or 3 usually erect very slender peduncles one of which is 
sometimes topped by 3 shorter peduncles: spathes green or slightly purplish, 15-20 mm. 
long, the bracts nearly equal, mostly attenuate and acute : interior scales about equalling 
the bracts or slightly exserted : flowers on slender exserted pedicels: perianth pale blue, 
about 10 mm. long: capsules pale, subglobose, 3-4 mm. high. 
In sand, peninsular Florida. Late winter and early spring. 
20. Sisyrinchium Nashii Bicknell. Resembling ©. Floridanum, but much more 
slender and delicate, and smaller throughout, flowering in midsummer instead of late 
winter and early spring. Leaves few ; blades 0.5-2 mm. wide, less closely and strongly 
striate than in the next preceding species, and frequently denticulate, especially toward the 
scarcely terete apex: scapes few, about twice as tall as the leaves, mostly 1 mm. wide or 
less, like the leaves sometimes obscurely roughened with minute papillae, the very narrow 
margins usually: minutely denticulate: braeteal leaf almost setaceously slender, much 
shorter than the almost filiform peduncles: spathes narrow, 13-15 mm. long, the bracts 
mostly thinner and less sharply pointed than in S. Floridanum, the inner one frequently 
surpassing the outer and scarious obtuse at the apex: perianth smaller than that of S. 
Floridanwm : capsules 2-3 mm. in diameter, on slenderly exserted pedicels 17-22 mm. long : 
seeds finely rugulose-pitted. 
In dry sandy soil, low pine land, peninsular Florida. Summer. 
21. Sisyrinchium solstitiàle Bicknell. Plants thinly tufted, chaffy and slightly 
fibrillose at the base, 2-4.6 dm. tall or taller, pale green or glaucescent, becoming brownish 
green when dry. Leaves erect; blades very straight, becoming 4 mm. wide, narrowed to 
the stiff acicular apex, striate-nerved and minutely rugulose, minutely serrulate, becoming 
smooth : scapes about twice as tall as the leaves, once or twice spirally twisted, becoming 
3 mm. wide, the firm wings hyaline-margined and obscurely serrulate, becoming smooth : 
inflorescence elongated, with 3 rather remote nodes each with a foliaceous bract and 2 
peduncles or the lower one with a slender branch: spathes dull green, 20-25 mm. long, 
the bracts stiff, nearly equal, the outer one narrowly acuminate : interior scales finally 
equalling the bracts : perianth blue, about 12 mm. long : flowers on slightly exserted pedicels. 
In high pine lands, peninsular Florida. Summer. 
22. Sisyrinchium recurvàtum Bicknell. Plants dull green, turning brownish when 
dry, 1.5-2.5 dm. high. Leaves about $ the height of the tufts ; blades 1.5-2.5 mm. wide, 
erect but rather thin, not closely nerved, the edges smooth or nearly so: scapes wing- 
margined, sometimes obscurely serrulate, the single node supporting a short erect bracteal 
leaf and 2-3 peduncles 5-11 cm. long: spathes 17-20 mm. long, the inner bract mostly 
longer than the very acute outer one and apiculate from a scarious-obtuse apex : interior 
scales equalling the bracts or nearly so : flowers blue-purple, about 10 mm. long : capsules 
on much exserted and recurved pedicels, subglobose or obovoid, dark brown, 2.5-4 mm. 
high : seeds 1 mm. in diameter or less, close-pitted. 
In sand, Longboat Key, Florida. Early spring. 
23. Sisyrinchtum graminoides Bicknell. Plants often not tufted, 1.5-6 dm. high, 
rather bright green, turning dark when dry. Leaves thin and grass-like, 3-1 the height 
of the scape ; blades 1.5-6 mm. wide, the edges like those of the scape minutely serrulate : 
scapes thin, wing-flattened, as broad as the leaf-blades, mostly forking into two peduncles 
5-20 em. long, subtended by a conspicuous bracteal leaf: spathes green, flat, the subequal or 
unequal bracts acute or acuminate, 15-20 mm. long, the interior scales much shorter : peri- 
anth blue, 10 mm. long : capsules thin-walled, subglobose, 3-6 mm. high, on slender spread- 
ing pedicels : seeds numerous, about 1 mm. in diameter, globose, pitted. 
BEST ays places and low meadows, Newfoundland to Minnesota, Florida and Texas. Spring and 
. 24. Sisyrinchium membranaceum Bicknell. Plants loosely erect or assurgent, in 
thin tufts, 20-25 cm. high, scarcely glaucescent, drying brownish green. Leaves half the 
height of the stem or more; blades 1.5-3.5 mm. wide, thin and membranous, promi- 
nently few-nerved, mostly serrulate-roughened, cuspidate-acute : scapes similar to the leaves, 
broadly thin-winged, mostly with 1 node bearing a short bracteal leaf 2-6 cm. long and 
two slender peduncles 4-10 em. long : bracts of the spathe subequal, cuspidate-acute, thin 
and delicately veined, mostly about 1.5 em. long : interior scales often equalling the bracts : 
perianth violet-blue : sepals and petals rather firm and membranous, 10-12 mm. long: 
ii pid ms subglobose, 3.5 mm. high, on slenderly exserted pedicels : seeds only 2-3 in 
i avity. 
In sand, Jackson County, Florida. Spring.
