In my account of the plants collected in California and Oregon by the United States Exploring Expedition, I have made this plant the type of a new , genus, ( Piptocalyz,) allied to Eritrichium, from which it differs in its naked corolla and deciduous calyx.

Annual; about a foot high. Radical leaves spatulate; the cau-line ones broadly linear, 1- 1J inch long; either entire or furnished on each side at the base ( sometimes only on one side) with a spreading, narrow, acute lobe, so that the leaves appear somewhat halberd- form. Racemes short, terminating the branches. Lobes of the calyx about three and a- half lines long. Corolla widely campanulate, almost rotate, about five lines long; the lobes short and rounded. Appendages ten, narrow, connivant in pairs between the bases of the filaments. Stames nearly equal, a little shorter than the corolla. Style somewhat exserted; 2- lobed at the | summit. Ovary with 15- 20 ovules attached to each placenta. This species resembles J8. phacelioides, Benth., but differs in the nearly sessile narrower leaves, the larger and broadly campanulate corolla, many- ovuled placentae, & c.
