or somewhat nodding, the lateral pedicels mostly short : calyx inflated, 

 ovate-oblong, 6 lines long, with broad acutish teeth : petals purplish, 

 8 lines long, the broad blade cleft to the middle (the rounded segments 

 entire, crenate, or bifid) and with a short narrow lobe on each side ; 

 appendages quadrate or ovate, thin and crenate ; claw broadly auricled, 

 very narrowly attenuated below : stipe of capsule a line long or 

 more. — Northw^estern Wyoming, collected by Dr. C. C. Parry on the 

 expedition of Capt. W. A. Jones to the Yellowstone in 1873. 



11. L. ELATA. Tall and slender, finely pubescent, slightly glan- 

 dular above, 1^ feet high or more: leaves narrowly oblanceolate, 2 to 

 4 inches long, acute or acuminate : flowers nodding or erect, on slender 

 pedicels : calyx inflated, ovate-oblong, 6 or 7 lines long, with triangular 

 acutish teeth: petals purplish, 9 to 12 lines long, the blade cleft to the 

 middle, with a narrow shorter lobe on each side ; appendages broad, 

 toothed ; claw not auricled, attenuate to a t'ery narrow base : stipe 

 of capsule nearly 2 lines long. — Collected in the Rocky Mountains of 

 British America by Bourgeau in 1858, and distributed as Silene 

 Sconleri. 



Lavatera insularis. a stout perennial, probably woody at base, 

 finely stellate-pubescent : leaves with a narrow sinus, 3 to 6 inches 

 broad, 7-lobed to the middle ; the lobes rounded and obtuse, coarsely 

 crenate : flowers solitary in the axils, on stout deflexed and curved 

 pedicels nearly an inch long and with one or two small bractlets or 

 naked : involucre of three nearly distinct oblong-spatulate acutish 

 bracts, 6 lines long : calyx 5-cIeft to the middle with broadly ovate 

 acute lobes, becoming an inch long in fruit : petals spatulate and un- 

 guiculate, emarginate, naked at base, apparently purplish yellow with 

 the claw dai-ker, 1^ inches long: styles not exserted : fruit half an 

 inch broad, slightly pubescent, about 10-carpelled, the sides of the 

 carpels smooth. — Received from D. Cleveland, Esq., of San Diego, and 

 collected on the Coronados Islands, 20 miles distant from that town. 

 Like the following, it differs from the two previously known California 

 species in the nearly distinct bracts of the involucre. 



Lavatera venosa. Similar in habit to the last, glabrous or 

 nearly so : leaves 3 to 4 inches broad, 7-cleft to the middle with tri- 

 ammlar acutish lobes: flowers two or three in the axils, on slender' 

 ascending naked pedicels 1 to H inches long: involucre of 3 nearly 

 distinct oblong-ovate acutish bracts, equalling the calyx, 3 or 4 (be- 

 coming 7) lines long: petals 15 lines long, cuneate-obcordate, deep 

 purple with darker veins, villous on each side at base: styles long- 

 exserted: fruit 5 lines broad, glabrous, about 10-carpelled: sides of the
