west in the other ranges, also Mt. Ibapah in the Deep Creek Moun- 
tains, Jeff Davis Peak and the Schell Creek Mountains in east- 
ern Nevada at high elevations, and probably in the East 
Humboldt Mountains; rare in Nevada and the Sierras of Cali- 
fornia, also northward to the Arctic regions. Much esteemed in 
cultivation where it is bluer. 
A. chrysantha, Gray. A. leptocera var. flava Gray Pl. Wright 
A. chrysantha, Gray Proc. A. A. S., 8, 621. Flowers 
Bide yellow throughout, one to two inches wide, spurs much 
longer than the sepals and very slender; sepals lanceolate, less 
than an inch long; petals as above. 
Lower elevations 6000 to 8000 feet altitude in Colorado, and 
higher altitudes southward to 10,500 feet in Arizona. Rocky 
Mountains of Colorado from Colorado Springs south through New 
Mexico and Arizona. Not yet known in Utah. This appears 
to hybridize with cerulea, the flowers being yellow or tinged 
with blue and spurs shorter. Should it become necessary to 
recognize the varietal name, this will become A. flava (Gray). 
A. longissima, Gray. Flowers yellow, spurs filiform, four 
inches long, and of about the same width throughout, petals 
nearly equaling the lanceolate sepals, elongated-spatulate. May 
be a form of the above. 
Northern Mexico, Palmer. 
++++ Spurs short and thick, six lines long or less, somewhat 
hooked at the end, not longer than the small sepals, 
nectary large, flowers small, not even an inch wide 
and often very small, nodding br ascending, yellow, 
but often tinged with red or blue. 
A. flavescens, Watson King’s Rep. 5, 10. Sepals lanceolate 
to oval, six to eight lines long; petal-limb somewhat dilated, 
about equaling the spur and nearly as long as the stamens, four 
lines wide, anthers elliptical-oblong, when the flowers are very 
small all the parts are small in proportion, except the stamens, 
which remain the same. All but the leaves often pubescent. 
Six thousand to nine thousand feet altitude along streams in 
very wet, exposed, and boggy places, rarely at high elevations, 
most abundant at low elevations, cafions of the Wasatch from
