Antennaria racemosa Hooker.
Collected by Allen in the "upper valley of the Nisqually." A much larger and greener plant than the preceding species.
Erigeron salsuginosus (Richardson) Gray.
The common pink aster or "daisy" of the grassy slopes. One of the most conspicuous plants at 4,000 to 6,000 feet altitude, but even ascending to 7,000 feet in a much dwarfed form.
Erigeron acris debilis Gray.
An insignificant white-flowered species, rare at about 7,500 feet altitude.
Erigeron compositus trifidus (Hooker) Gray.
A small pinkish aster, with the leaves cut into linear lobes. Growing in decayed lava at 7,500 feet altitude.
Erigeron speciosus De Candolle.
A handsome species with entire ciliate leaves and rather numerous heads, with deep violet rays. Collected by Allen in the Goat Mountains, No. 222.
Erigeron aureus Greene.
(Aplopappus brandegei Gray.)
A beautiful little aster with bright golden rays, the solitary heads on scapes two or three inches tall. Abundant in the pumice, 7,500-8,000 feet altitude.
Aster ledophyllus Gray.
A tall species with leafy stems, and numerous middle-sized heads with pink-purple rays. The leaves are entire, pubescent on the under side. Not uncommon on the grassy slopes at 5,000 feet altitude.
Aster foliaceus frondeus Gray.
(Aster amplifolius Greene.)
A species with broad half-clasping leaves and deep-violet-colored rays. Professor Greene's type came from Mount Rainier, but his species seems not to differ from the plant earlier described by Dr. Gray.
Oreostemma alpigena (Torrey & Gray) Greene.
(Aster pulchellus D. C. Eaton.)
A low plant with narrow tufted leaves, the scapes bearing one or rarely two large heads. The rays are deep violet. The plant is common in the pumice fields at 7,000-8,000 feet altitude, but, strange to say, also occurs on the borders of small lakes at the foot of Pinnacle Peak at 4,500 feet elevation. In exposed places at high altitudes the leaves are often curiously twisted. It was originally described from the specimen collected on Mount Rainier by Tolmie.
