1-1.25 mm. wide, sometimes involute; scapes grooved; inflorescence 3-10 

 cm. long, many-flowered, the branches ascending; flowers scattered, rather 

 distant; perianth straw-colored, 3-4 mm. long; sepals and petals nearly 

 equal, lanceolate-subulate, slenderly acute or acuminate, appressed or 

 erect; stamens 6, one-half as long as the perianth; anthers much shorter 

 than the filaments; capsule oblong or rarely ovoid-oblong, about as long 

 as the perianth, obtuse or barely apiculate; seeds oblong, 0.35-0.50 mm. 

 long. In dry woods or on prairies, 111. to Wyo., Tenn., Miss, and Ark. 

 Spring and early summer. Differs from /. secundus in the longer bracts 

 of the inflorescence, the larger perianth, the flowers scarcely or not at all 

 secund. 



nb. Juncus Dudley! Wiegand. DUDLEY'S RUSH. Plants 3-10 dm. tall, 

 pale green. Leaves basal; blades about one-half the length of the scape, or 

 less, very narrowly linear, flat, frequently somewhat involute; scapes 

 tufted, often relatively stout, but wiry, striate-grooved; inflorescence 2-5 

 cm. high, or rarely slightly larger, usually rather congested, considerably 

 exceeded by its bract, few-flowered; perianth green or pale straw-colored, 

 4-5 mm. long; sepals and petals firm, nearly equal, lanceolate-subulate, 

 acute, more or less spreading, scarious-margined; anthers slightly shorter 

 than the filaments; capsules ovoid-oval, shorter than the perianth, some- 

 what apiculate; seeds oblong, 0.37-0.45 mm. long, apiculate at each end. 

 In damp soil and open places, Me. to Ont., Saskatchewan, Wash., Penn., 

 Tenn. and Mex. Spring and summer. Differs from /. tenuis by the yel-

8. Juncoides bulbosum (Wood) Small. BULBOUS WOOD-RUSH. Base 

 of the plant accompanied by bulblets. Foliage almost glabrous or some-

 dm. tall; inflorescence umbel-like, the peduncles very unequal at maturity; 

 sepals and petals ovate-lanceolate or lanceolate, 2-2.5 mm. long, brown- 

 ish, acuminate, neither manifestly soft nor hyaline at the apex; capsule 

 broadly obovoid, or globose-obovoid, often nearly as thick as long, sur- 

 passing the sepals or sometimes about equalling them. [Lusula campestris 

 var. bulbosa Wood.] In woods, thickets and open sandy places, Va. to 

 Kans., Ga. and Tex. Spring. 



P. 263, after Allium vineale, add: 



6a. Allium carinatum L. KEELED GARLIC. Similar to A. vineale. Bulb 

 ovoid, its coats membranous; stem terete, leafy to about the middle, 2.5 

 dm. tall or less; leaves linear, channeled below, flat toward the apex, 2-3 

 mm. wide, prominently 3-5-nerved; bracts of the umbel 2, narrowly linear, 

 one much longer than the other; umbel erect, bearing either bulbs or cap- 

 sules; pedicels filiform, 2-4 cm. long, filaments simple, not toothed.

 species or more, natives of Europe and Asia. 



i. Tulipa sylvestris L. WILD TULIP. Bulb ovoid, 2.5 cm. long or 

 less; stem about 3 dm. high, with 1-3 linear-lanceolate acuminate leaves; 

 flower yellow, 7-9 cm. broad; inner perianth-segments rather broader 

 than the outer, acute; filaments pubescent at the base, In meadows, Bucks
