=Polemonium humile= Roemer & Schultes.

A handsome plant with pinnate leaves and corymbs of pale blue flowers.

=Gentiana calycosa= Grisebach.

An elegant plant with deep blue bell-shaped flowers. Abundant along the rills at 5,000 feet. The species was described from Mount Rainier specimens collected by Tolmie in 1833. Grisebach also described a variety _stricta_, based on very trivial characters.

=PRIMULACEAE.= (Primrose Family.)

=Dodecatheon jeffreyi= Van Houtte.

(_D. crenatum_ Greene.) (_D. viviparum_ Greene.)

This peculiar plant occurs along the Nisqually trail at about 3,000 feet alt.i.tude.

=Allotropa virgata= Torrey & Gray.

This queer plant is abundant in coniferous woods on the north side of the mountain, but it is doubtful whether it comes within our limits.
