BOTANICAL EXCURSION TO ANTELOPE VALLEY. 155 
plant gathered, and of which we had seen specimens on the 
way, was Oollinsia Davidsoni, Parish. It seems to be 
abundant all along the foothills from Lancaster. The type 
specimens from the latter place possessed a smooth calyx, 
while some of those here, and near Manzana, were more or 
less hirsute, nevertheless, it proves to be a good species. 
The beautifully colored Astragalus Purshi, Dougl., was 
abundant, growing with Senecio multilobatus, T. & G.; the 
latter, common enough on the coast hills at an altitude of 
four thousand feet, I have not found further east on this 
range, although it extends inland on the northern mountains 
as far as Tehachapai. A few plants, the only ones seen, of 
Balsamorrhiza deltoidea, Nutt., were noticed among the scrub 
oak, and Ribes leptanthum, Gray, Phacelia ciliata, Benth., 
Streptanthus acutirostris, and Galiwm Andrewsii, Gray, 
were all in flower. Ina sheltered nook my first specimen of 
Bromus carinatus, Hook., was gathered, and on the margin 
of the marsh, near the station, appeared Microseris montana, 
Greene, and a variety of Vicia Americana with hirsute 
leaves. 
Tn the afternoon we climbed the steep slopes of the hills 
on the northern side of the pass, which, on account of the 
trespassing sheep, were nearly devoid of underbrush but 
copiously covered with Lupinus formosus, var. Bridgesi, 
Greene, L. Chamissonis, Esch., var. longifolius, Wats., L. mi- 
cranthus, Dougl., Layia heterotricha, H. & A. Gilia 
tenuiflora, Benth., and, more sparingly, G. inconspicua, 
Dougl., var. sinuata, Gray. In the shade of some live oaks 
Ellisia membranacea, Benth., was abundant. On the rocky 
ground grew Streptanthus heterophyllus, Nutt., Gnothera 
gaureflora, T. & G., and a few plants of Astragalus 
Antiselli, Gray. : 
On the next day we took the stage back to Manzana, col- 
lecting on the way Madia elegans, Don, Troximon hetero- 
phyllum, Greene, Malacothrix Coulteri, Gray, and Mirabilis 
multiflora, Gray, var. pubescens, Wats., the last not yet in 
flower. For the next three days we made Manzana our 
headquarters in order to explore the hilly district adjoining.
