SCROPHULARIACEAE. (Figwort Family.)
Chelone nemorosa Douglas.
A handsome plant with opposite serrate leaves and corymbs of purple-red flowers somewhat like those of the foxglove. Dry cliffs and slopes at 5,000 feet altitude. Also reported by Gorman as occurring at Longmire Springs.
Pentstemon confertus Douglas.
A species with entire leaves and dense clusters of small pale yellow flowers. In its typical form the species is one to two feet tall, but on Mount Rainier, where it occurs at from 7,000 to 8,000 feet elevation, it is reduced to two to four inches high, but otherwise not differing from the type.
Pentstemon procerus Douglas.
Like the above, but blue flowered. It occurs at 8,000 feet and on Rainier is scarcely two inches tall, while at lower altitudes it is frequently as many feet high. This dwarf Alpine form has been described by Professor Greene as a new species under the name of Pentstemon pulchellus. It is an interesting fact that Tolmie long ago collected on Mount Rainier a dwarf species which Hooker named Pentstemon tolmiei. But alas, the specimens are in fruit, and it is past finding out now whether his plant was the yellow-flowered or the blue-flowered form. Most likely, however, it was the latter, as that is far more frequent than the yellow-flowered form.
Pentstemon diffusus Douglas.
A handsome species with serrate leaves and blue-purple flowers. Mount Rainier, Piper 2068. Goat Mountains, Allen 129.
Pentstemon ovatus Douglas.
Much like the preceding plant, differing essentially in the anthers. Collected by Allen "mountains near the upper valley of the Nisqually," and by the writer on the slopes of Mount Rainier.
Pentstemon menziesii Hooker.
A dwarf prostrate plant with thickish evergreen toothed leaves and dull purple flowers, abundant on the rocks at 8,000 feet elevation. A variety with the leaves entire instead of denticulate, P. davidsonii Greene, also occurs on the mountain.
Pentstemon rupicola (Piper) Howell.
Much like the preceding, but with glaucous leaves and rose-colored larger flowers. The writer found it originally on the perpendicular cliffs, at the limit of trees above "Camp of the Clouds."
Collinsia tenella (Pursh) Piper.
Collected by Flett on an old moraine along the Carbon Glacier.
