A. mollis Greene |. c. 20. Krynitzkia mollis Gray. Copiously soft- 
villous, even to the calyx: stems rather stout, spreading or ascending, at 
length a foot or more long: leaves linear-lingulate, 2-3 inches long hy 3-4 
lines broad, obtuse: racemes at length elongated, bractless: limb of the 
corolla 3-4 lines broad: nutlets trigonous-ovate, slightly obcompressed, 
hardly at all carinate on the back, coarsely rugose-areolate, attached bv a 
quarter or a third of their length to an oblong-pyramidal gynobase, the 
eee ee Borders of alkaline ponds, southeastern Oregon to

Small dichotomously branched annuals with narrow leaves and 
small tlowers sessile in the forks or in the axils of leaves or 
bracts. The root giving a deep purple stain. Calyx early cir- 
cumscissile, the 5-cleft upper portion falling away, leaving the 
membranaceous base persistent around the fruit. Pedicels very 
short, persistent. Corolla with naked and open throat, the tube 
not surpassing the calyx. Anthers mucronate, included. Fruit 
of 4 rather distinctly margined nutlets. : 
P. cireumscissus Torrey l.c. Krynitzkia circumscissa Gray Hispid- 
canescent throughout: stem 1-4 inches high, densely branched from the 
base: leaves linear or the lowest spatulate, 3-6 lines long, crowded on the 
apper part of the branches: calyx hispid, its linear lobes foliaceous, about 
a line long: limb of the white corolla about a line broad: nutlets oblong- 
ovate, not carinate, smooth or minutely tuberculate, attached for nearly 
their whole length to the pyramidal-subulate pynebase, the ventral groove 
narrow and divaricately forked at the base. On dry sandy plains, eastern 
Oregon to Brit. Columbia, California and Arizona,

Hirsute-canescent small annual herbs with chiefly radical 
leaves in rosulate tufts and small white flowers on persistent ped- 
icels in dense leafy-bracted geminate racemes: the root giving a 
deep purple stain. Calyx 5-parted to the base, in fruit campanu- 
ulate, persistent: the segments nerveless and not bristly-hispid. 
Style enlarged in fruit and persistent. Nutlets neither margined 
nor carinate, erect, attached for their whole length to a slender 
columnar gynobase by a groove that does not fork nor enlarge at 
base, smooth or papillose-scabrous. : | 
E. micrantha Greene 1. c.  Krynitzkia micrantha Gray. Hirsute- 
canescent: stem slender, 2-5 inches high, at length diffusely branched, the 
numerous racemous branches repeatedly dichotomous and copiously leafy- 
bracted: leaves linear, 2-4 lines long: racemes mostly geminate with a 
flower in the fork, 4-6 lines long, densely flowered: corolla barely a line 
high, and its lobes 14-24 of a line long, obscurely appendaged in the throat: 
style becoming thicker than the gynobase, or even pyramidal; nutlets 
oblong-ovate, acute or acuminate, smooth and shining or dull and punc- 
ticulate. Dry plains, southeastern Oregon to California, Utah and Arizona-
