LiTHOSpERMUM ? CIRCUMSCISSUM, Hook. and Arn., Bot. Beech. 

 Voy., suppl. p. 370. — On Green River. 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, {Piptocalyx,) allied to Eritrichium, from which it diifers in 

 its naked corolla and deciduous calyx.

EuTOCA HETEROPHYLLA, Torr. (n. sp.) — Erecta, scabro-pubescens; 

 foliis oblongo-linearibus subsessilibus, integris vel ad basin utrinque 

 unilobatis, lobis oblongis v. linearibus; floribus brevi-pedicellatis ; 

 lobis calycinis spathulata linearibus obtusiusculis ; corolla patenti- 

 campanulata calyce sesquilongiore ; placentis multiovulatis. — Val- 

 ley of the Salt Lake, on the eastern side. 



Annual ; about a foot high. Radical leaves spatulate ; the cau- 

 line ones broadly linear, 1-1 J 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 E. phacelioides, Benth., but differs in the 

 nearly sessile narrower leaves, the larger and broadly campanulate 

 corolla, many-ovuled placentae, &c.
