like F. Carolinensis, and likewise destitute of a crown. It is, perhaps, F. verticillata, Hook. 
Fl. Bor.-Am., but not of Walter. It has a nearly naked panicle, and lunate solitary glandular

Ipomma SAGITTATA, Desf.? I. sagittifolia, Hook. & Arn. Bot. Beech. p. 151. Hills near 
Punta de los Reyes, California; April 17. This is probably the plant of Hooker and Arnott, 
but not Convolvulus sagittifolius, Miche. The leaves are broader, and the auricles are deeply 
emarginate, or even 2-lobed at the summit. The one-flowered peduncles are longer than the 
leaves, and furnished with two small alternate lanceolate bracts a short distance below the 
flower. Corolla nearly as large as in Calystegia sepium, whitish, with pale purple stripes. 
CONVOLVULUS ARVENSIS, Linn.; Choisy in DC. Prodr. 9, p. 406; var. viLLosus, Choisy l. c. 
Hill sides, Sonora, California; May 9. Stems prostrate, branching from the root. Leaves vary- 
ing from ovate to narrowly lanceolate, strongly hastate or sagittate. Peduncles longer than 
the leaves, with a pair of opposite lanceolate mostly sagittate bracts a little below the flower. 
CoNVOLVULUS (n. sp.?): canescenti-tomentosus; caule prostrato e, basi ramoso; foliis lato- 
cordatis brevissime acuminatis, auriculis angulari-bilobis; pedunculis unifloris axillaribus- 
Hill-sides, Downieville, Yuba river, California; May 22. Our specimens have only young 
flower buds, so that the genus cannot certainly be ascertained. The plant has never come 
under our observation before.

NICOTIANA PLUMBAGINIFOLIA, Dunal in DC. Prodr. 13, pars. 1, p. 569. Var? ۲: 
annua; caule glanduloso-pubescente subsimplici; foliis oblongo-lanceolatis acutiusculis glabri- 
usculis, inferioribus in petiolem angustatis, superioribus sessilibus basi angustatis; panicula 
terminali laxiuscula ; calyce glanduloso-pubescente, laciniis lanceolato-linearibus inequalibus, 
corolla hypocraterimorpha, tubo elongato calyce 2-3-plo longiore, limbi laciniis lato-ovatis 
obtusiusculis. Knight's Ferry, Stanislaus river; May. We are unwilling to propose this as 
a new species, since there are so many others in the same genus that are very imperfectly 
known. Our plant does not agree with any Nicotiana described by Dunal, (l. c.,) but it seems 
to approach the nearest to N. plumbaginifolia. ; pot. i.
