New Species from the Western United States 



By p. a. Rydberg 



Juncus Suksdorfii 



Stem about 3 dm. high, strict, light green, 2—3 mm. in diame- 

 ter ; leaves terete or slightly flattened, distinctly septate ; the basal 

 ones short ; stem leaves, except the upper ones, often 3 dm. lon^ 

 all with a conspicuous, scarious sheath ; heads in a contracted pan- 

 icle, brown and shining, 5-8-flowered ; bracts ovate, cuspidate- 

 acuminate ; perianth segments subequal, about 4 mm. long, nar- 

 rowly lanceolate, acute or acuminate ; stamens 6 ; anthers longer 

 than the filaments ; style long-exserted ; capsule dark brown and 

 shining, oblong, acuminate, 3 -angled. 



Dr. Watson has labeled \.h.\s Junciis Ncvadeiisis van, to which it 

 may be nearest related if the structure of the flower is taken in 

 consideration. It is different in habit, however, being much stouter, 

 having more numerous and larger heads, and longer leaves.

Allium Neo-Mexicanum 



Bulb oblong, membranaceous, crowning a more or less persis- 

 tent rhizome ; coat membranaceous ; scape slender, terete ; leaves 

 narrow, 1-3 mm. wide, apparently almost flat, slightly keeled ; 

 umbel 8— 20-flowered, nodding ; involucre very small ; perianth- 

 segments oblong-ovate, acute, nearly white, without a distinct mid- 

 vein ; stamens and style exserted ; capsule 6-crested. 



This resembles most A. ccrnuuni, but differs in the fewer flow- 

 ered umbel, the narrower perianth-segments, and in the thinner 

 and narrower leaves, which are only slightly keeled.
