 near Camden, N. J. Sept.-Oct. 



P. 248, after Juncus tenuis, insert: 



11a. Juncus interior Wiegand. Inland Rush. Plants 5-10 dm. tall, 

 light green. Leaves basal; blades about one-third the length of the scape. 

 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 Ariz. 

 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. 



11b. Juncus Dudleyi 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., Conn., 

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

 yellow-brown cartilaginous margins of the leaf-sheaths. 



P. 248, after Juncus Vaseyi, insert: 



13a. Juncus Oronensis Fernald. Orono Rush. Perennial, tufted, 

 similar to /. Vaseyi, but the inflorescence elongated and much shorter 

 than the filiform lower bract, which is sometimes 9 cm. long; branches 

 of the inflorescence nearly erect, the flowers secund; perianth 4-5 mm. 

 long; stamens 6, half as long as the perianth, the anthers as long as 

 the filaments; capsule oblong, triquetrous, shorter than the perianth; 

 seeds larger than those of /. Vaseyi, about 15-ribbed, 1 mm. long, 

 short-tailed. In swamps, Me. 



P. 252, before Juncus megace*phalus, insert: 



34a. Juncus validus Coville. Sturdy Rush. Stout, 1 m. high 01 

 less, the compressed stem 1-3-lcavcd. Leaves 1-2 dm. long, 2-4 mm. 

 wide, compressed, the septa complete; inflorescence 3.5 dm. long or less, 

 its branches stiff, spreading; heads several or numerous, globose, 12- 

 15 mm. in diameter; perianth 4-5 mm. long, its parts subulate, about 

 twice as long as the 3 stamens; capsule subulate, often falcate, i-celled, 

 exceeding the perianth, beakless, dehiscenl to the base; seeds broadly 

 oval, reticulate in about 20 longitudinal rows. In sandy soil, Mo. to 

 Miss, and Texas. 



P. 254, after Juncoides campestre, add: 



8. Juncoides bulbdsum (Wood) Small. Bulpous Wood-rush. Base 

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

 what webby on the leaf-margins and at the tops of the sheaths; stems 1-4 

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

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

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