Mimulus lewisii Pursh.
Abundant along rills, 4,000 to 5,000 feet altitude. Easily known by its opposite dentate leaves, viscid pubescence and rose-purple corollas. The original specimens were collected in Idaho by the Lewis and Clark expedition.
Mimulus breweri (Greene) Rydberg.
(Eunanus breweri Greene.)
A minute species with pale purple flowers, abundant on dry cliffs near "Camp of the Clouds."
Mimulus alpinus (Gray) Piper.
(M. luteus alpinus Gray.)
(M. scouleri caespitosus Greene.)
A dwarf plant with matted stolons, the bright yellow flowers painting the cliffs wherever there is dripping water. The Mount Rainier plants match closely the original types collected by Dr. Parry in Wyoming, so that Professor Greene's name is clearly a synonym of the earlier one of Gray.
Veronica alpina Linnaeus.
A small plant two or three inches high, with several pairs of small, ovate, pubescent leaves, and a terminal raceme of small blue flowers. Common at 4,500 to 5,500 feet altitude.
Veronica cusickii Gray.
A very similar plant to the above, but with larger blue flowers and smooth leaves. Abundant just above "Camp of the Clouds."
Veronica allenii Greenman.
Much like the preceding species, but with smaller white flowers. A new species discovered by Allen "near Paradise River at 5,400 feet elevation."
Castilleja miniata Douglas.
This vivid scarlet "Painted Cup" or "Indian Pink" is easily known by its entire leaves. Not infrequent at 5,000 to 6,000 feet; also occurring at lower altitudes down to sea-level.
Castilleja angustifolia hispida (Bentham) Fernald.
Very similar to the last, but the flower spikes shorter and the leaves cut-lobed. Bear Prairie, Allen.
Castilleja rupicola Piper.
Like the last, but smaller, the leaves usually purplish and deeply cut, the flowers intensely scarlet and with very long beaks. On the cliffs on both sides of Sluiskin Falls, whence the original specimens were obtained.
