3. NEMASTYLIS Nutt. 
Stems round, from coated bulbs, with few plicate leaves, few 
fugacious flowers from 2-bracted spathes, spreading perianth with 
similar segments, filaments more or less united into a tube, the slender 
2-parted style-branches of the short style exserted between the 
anthers, minute terminal stigmas, oblong or ovate truneate pod 
(dehiscent at summit), and globose or angled seeds. 
1, N. coelestina (Bart.) Nutt. Stems 4 to6dm., high, from asmall roundish bulb: 
radical leaves elongated, few, the upper stem-leaves bract-like: perianth bright 
blue, terminal, mostly solitary; segments oblong-obovate: pod obtusely 3-angled: 
seeds angular, brown. (/ria cwlestina Bart.) —Extending into eastern Texas from the 
Gulf States, 
2. N. acuta (Bart.) Herb. Stems 1.5 to 8 dm, long, bearing 2 or 3 long-peduneled 
clusters, bracteate at the fork by a large linear leaf, and sometimes with one below 
it: radical leaves 2 or 3, linear, plicate, 1.5 to3 dm. long: spathe 2 or 3-flowered, 
2.5 to 3 em, long, outer valve shorter: perianth bright blue; segments ovate- 
cuneate, subequal, 2.5 em, long: filaments very short; anthers 6 to 8mm, long, 
curling up: style-branches half as long as the anthers: pod turbinate. (Iria acuta 
Bart. N. geminiflora Nutt.)—From Arkansas through eastern and southern Texas. 
4. 5ISYRINCHIUM L. (BLvur-b yep Grass.) 
Low slender perennials, with fibrous roots, mostly branching 2-edged 
or winged stems, grassy or lanceolate leaves, fugacious flowers (on 
slender pedicels) clustered within 2 sheathing herbaceous bracts, a 
bractlet subtending each pedicel, 6-parted perianth with spreading 
divisions nearly alike, stamens monadelphous to the top, and a mem- 
branaceous subglobose pod. 
1. S. angustifolium Mill. Scape (1 to 8 dm. high) winged or wingless, simple: 
spathe solitary and terminal, its outer bract more or less elongated: flowers delicate 
blue, changing to purplish (rarely white): divisions of the perianth more or less 
notched, bristle-pointed and ciliate: mature seed globose, large (1mm. broad), faintly 
pitted or nearly smooth, (S. mucronatum Michx. 8. Bermudiana, var. mucronatum 
Gray.)—Western Texas, common along the Rio Grande. Var. GENICULATUM Herb. (S. 
geniculatum Herb.), from the San Antonio through central Texas, has slender stems 
narrowly winged low down and often bearing 1 or 2 leaves below the fork, and 
smaller tlowers, pods, and seeds. 
2, S, anceps Cav. Scape (1.5 to 4.5 em. high) usually branching and bearing 2 
or more peduncled spathes: seeds more ovate, much smaller, deeply pitted. (8. Ber- 
mudiana, var, anceps Gray.)—From San Antonio to central and eastern Texas. 
3. S. bellum Watson. Stem(1.5to6 dm. high) with 1 to 3 nodes: leaves 2 tod mm. 
wide, shorter than the stem: peduncles 1 to 4 (usually 2) at each node, 5 to 10 em, 
long, equaling the bract: spathes of 2 nearly equal bracts (1.5 to 2.5 em. long), 
scabrous on the keel, 4 to 7-flowered: flowers somewhat pubescent (as also the 
ovary), light purple, the segments 3-toothed or mucronate, shortly ciliate: anthers 
very small: stigmas scarcely exserted: pod depressed-globose or obovoid (4 to Gmm, 
broad); seeds obscurely pitted.—Reported from Gillespie County. 
4. S. Thurowi Coult. & Fisher. Low (4 to 7 em, high), cespitose, procumbent: 
stems rather broadly winged, with a solitary pedunele at each node: leaves short, 
seareely 2mm. broad: perianth 4 or 5 mm. long, yellow: outer bract of the 2 to 
4-flowered spathes a little longer than the very slender pedicels: pod oblong or pear- 
shaped (4 to 5mm. long), prominently transversely wrinkled between the seeds: 
seeds 10 to Tt in each cell, depressed-globose, very small (seareely 0.5 mm, broad), 
black, deeply punctate.—Near Hockley (Tharow),
