Juncus parous sp. nov. 



Stem 3-6 dm. high, laterally flattened and distinctly winged ; 

 leaves equitant, laterally flattened, septate, 2-3 dm. long, 3-5 mm. 

 wide; sheaths with scarious margins that taper upwards ;md 

 without any indication of an auricle ; bracts 1-2 cm. long, green 

 with more or less scarious margins ; heads few, 1—8, often clustered, 

 1 5-20-flowered ; bractlets lanceolate, light brown; petals and 

 sepals lanceolate, sharply acuminate, subequal, light brown or 

 greenish on the back ; stamens usually 6 ; style shorter than the 

 petals ; capsule oblong, acute, shorter than the petals ; seeds 

 apiculate. 



This is still more closely related to J. saximontanus than the 

 former, but is easily distinguished by the light-colored heads and 

 the total lack of auricles. It grows in mountain meadows of Colo- 

 rado and New Mexico.

Juncoides subcapitatum sp. nov. 



Stem 3—4 dm. high, glabrous ; leaf-blades lanceolate, acumi- 

 nate, glabrous, 4-10 cm. long, 5-10 mm. wide; bracts 2.5-3 cm - 

 long, lanceolate, foliaceous ; inflorescence compact, consisting of 

 6-10 heads, conglomerate and forming an irregular head; bract- 

 lets ovate, those subtending the individual flowers about half as 

 long as the sepals; these and the petals subequal, 1.5-2 mm. 

 long, ovate, acuminate, dark brown but lighter on the midrib ; 

 capsule broadly obovoid, obtuse, shorter than the petals ; seeds 

 about 1 mm. long, ellipsoid, obtuse, dark brown, minutely punctate. 



Notwithstanding the capitate inflorescence, the large foliaceous 

 bracts, and the shorter capsule, it is most closely related toy. parvi- 

 florum, which it resembles in leaves and flowers. The type grew 

 near timber-line on a mountain above Silver Plume.

Allium macropetalum sp. nov. 



Bulb obovoid, about 4 cm. long and 2 cm. thick, coated with 

 long loose fibers ; leaves about 2 cm. long, almost equaling the
