way, the borders of alkali flats are decorated with masses of 
Allocarya mollis. Farther down, spread the long slender vines 
of Astragalus Lemmoni, and beyond it, the robust, large-podded 
Astragalus Webbert, named at my request in honor of Dr. D. G. 
Webber, who attended me faithfully and aided me greatly there- 
after in long excursions. 
Near the latter, and carpeting the valley with soft white 
mats two to three feet wide, reposes Astragalus Pulstferae, ded- 
icated at my request to a flower lover of the next county—Mrs. 
Ames—by her maiden name of Pulsifer. <A little farther, hid- 
ing under the sage bushes near Beckworth Pass, stands erect the 
fourth member of this interesting genus, Astragalus Casez, 
named at my request in honor of Professor E. L. Case, the 
teacher of the Sierraville school, and my assistant during many 
a weary climb. The fifteenth new species from this compara- 
tively small valley became J/vesza Webberz, peering out of the 
sage brush on the Doctor’s ranch. 
Some of these plants were found extending over large spaces 
of Sierra valley, and a few reach other regions. Perhaps the fol- 
lowing strictly descriptive statements may prove useful: 
TRIFOLIUM LEMMONI Wats. Accidentally located in Bot. 
“Cal. on “Lassen’s peak.” Its real home is in Sierra valley along 
the cobble-stone borders of the valley and in stream beds. Often 
in cracks of rocks. 
CASTILLEJA LEMMONI Gray. Borders of Sierra vallev and 
ascending up in the forest to sub-alpine stations, forming small 
tufts. 
ANTENNARIA MICROCEPHALA Gray. Extremely local in 
meadows of Sierra valley, and earlier detected in Washoe valley, 
Nevada. 
EPILOBIUM BREVISTYLUM Barbey. Along the high, dry 
banks of streams in Sierra valley.
