Vagnera sessilifolia (Baker) Greene.
Common in moist woods up to 3,000 feet altitude.
Streptopus curvipes Vail.
Common in moist woods at 3,000 feet. Distinguished from the Eastern S. roseus by its small size, simple stems, and creeping rootstocks.
Lilium columbianum Hanson.
The wild tiger lily occurs on dry slopes near Longmire Springs and in Paradise Park, at 5,000 feet elevation.
Fritillaria lanceolata Pursh.
Goat Mountains, Allen, No. 235.
Erythronium montanum Watson.
The white-flowered adder's tongue, so abundant in Paradise Park, up to 5,500 feet altitude.
Erythronium parviflorum (Watson) Goodding.
Much like the preceding, but the flowers yellow. Frequent along rills at 5,500 feet.
Clintonia uniflora (Schultes) Kunth.
Abundant in the coniferous forests at 2,000 to 4,000 feet altitude. Easily recognized by its tuft of two to four radical leaves, which are oblong in form, and its delicate scapes, three or four inches high, bearing a single white flower. The berry is blue.
Trillium ovatum Pursh.
The wake-robin is plentiful at 3,000 feet altitude.
Tofieldia intermedia Rydberg.
This species has been confused with both T. glutinosa and T. occidentalis. From the former it differs principally in its seed characters, otherwise being so similar that there are no distinguishing characters in the flowering specimens. All the Cascade Mountain specimens apparently belong to T. intermedia, because no plant with the seed character of T. glutinosa has as yet been found in that range of mountains.
