2. SISYRINCHIUM, L. Blue-eyed Gbass. 



Perianth 6-parted. Capsule membranaceous, subglobose.— Steins simple 

 or branched, usually geniculate and winged, with linear-lanceolate or grass-like 

 radical leaves, and fugacious flowers on slender pedicels, clustered within 

 2 sheathing herbaceous bracts, with a scarious bractlet subtending each 

 pedicel. 



1- S. aneeps, L. Scape broadly winged, and the outer leaf of the very 

 unequal spathe longer than the flowers. — S. Bermudiana, var. aneeps, of 

 Gray's Manual. In the Atlantic States, but extending westward to 'the 

 Wasatch and Uintas (Watson). 



2. S. mueronatum, Michx. Scape slender and narrowly winged : leaves 

 very narrow, those of the spathe sharp-pointed and unequal, one of them 

 usually longer than the flowers. — .V. Bermudiana, var. mueronatum, of Gray's

Order 78. AMARYLLIDACEjE. 



Like lAliacex, but ovary inferior. Differs from Iridacece in having 

 six stamens and leaves not equitant. 



1. HYPOXYS, L. Stah-grass. 



Perianth persistent, spreading; the 3 outer divisions a little herbaceous 

 outside. Pod crowned with the withered or closed perianth. Seeds globular. 

 — Stemless small herbs, with grassy and hairy linear leaves and slender few- 

 flowered scapes, from a solid bulb. 



1. H. juncea, Smith. Sparingly hairy: scapes 1 to 3, filiform, 1 or 

 2-flowered, 4 to 9 inches long : bracts bristle-like, shorter than the villous 

 pedicels : the three exterior divisions of the perianth greenish and hairy with- 

 out : seeds black, minutely fitted. — Colorado (Brandegee). 



Order 79. LJEIACEiE. (Lilt Family.) 



Terrestrial plants, mostly herbaceous, with perfect flowers, a regulai 

 corolla-like 6-cleft or divided perianth, stamens opposite the segments, 

 ovary 3-celled and superior becoming a few or many-seeded 3-celled 

 capsule or berry. — Stems chiefly from tunicated or scaly bulbs, or 

 corms, or rhizomes. — Watson's Revision, Proc. Am. Acad. xiv. 213. 



I. Flowers with scarious bracts, a persistent perianth with segments one to several-nerved, 

 perigynous stamens with introrse anthers, and an undivided and mostly persistent 

 style. 

 * Inflorescence umbellate upon a naked scape from a bulb or corm ; sessile upon a short 



rootstock in Leucocriimm. 



*- Bracts (usually 2) broad and spathaceous : capsule more or less deeply lobed : perianth 



cleft nearly to the base : bulb mostly tunicated.
