VOL. I. ] Flora of Yo Semite. 163 
ous flowers and small bur-like capsules, occurs in deeply shaded 
places at the upper end of the valley. 
Among the conspicuous umbelliferous plants of the region are 
Angelica Breweri, Peucedanum utriculatum and Selinum capitella- 
tum, the latter with its ball-like secondary umbels, near the river 
borders. The Umbelliferee of the region are seldom collected in a 
sufficiently mature state. 
Valeriana capitata may be found at various places, notably above 
Glacier Point, on the heights above the valley. 
The Composite form, as.everywhere with us, a considerable pro- 
portion of the flowering plants. The silvery Antennarias, 4. ar- 
geniea and A. luzulotides, spread their tufts over rocky and barren 
spots on the declivities. Evriophyllum confertiflorum, common on 
our coast, has in the valley a variety—s7ifidum—which brightens 
many a gravelly slope with a blaze of gold. £. nudbigenum, first 
described from plants collected on the slope of Clouds Rest, was 
brought this year by Mrs. Dodd from the Little Yo Semite. Ar- 
nica mollis, with its rather large, rayless and nodding heads, is 
common in niches about the cliffs. 
The purple-flowered Lessingia lepioclada is abundant at the lower 
end of the valley. The showy Madza elegans, either with or with- 
out a brown eye, brightens the early morning with its showy flow- 
ers. MM. Yosemitana, which bears a considerable resemblance to 
the much more abundant Hemizonia Durandi, may be found some 
distance above the Nevada Fall on the way to Clouds Rest. Che- 
nactis Douglasti, with its dissected leaves and brush-like head of 
flesh-colored flowers, is particularly abundant towards the lower 
end of the valley. //udsea heterochroma, tall and branching, with 
large heads of yellow and purple, grows a short distance up the 
valley walls at Indian Cafion and several other places. 
One of the species of ‘‘sneeze-weed,’’ Helenium Bigelovit, 
_ grows in wet places about the valley. Various forms of Senecio 
aureus are found about the heights. .S. dwgens grows on the de- 
clivities and .S. ¢riangu/aris in wet places, both in the valley and on 
the heights. Phalacroseris Bolanderi, described from this region, 
grows in wet meadows near Sentinel Dome; 770x7mon Nuttallit and 
_ Microceris nutans are found at moderate elevations about the valley, 
and Hieracium Breweri, with its long-hairy leaves and yellow flow- 
ers, inhabits little clefts in the valley walls.
