Ipomma saarrrara, 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, Michx. 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.

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.

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,

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, (1, c.,) but it seems 
to approach the nearest to N. plumbaginifolia. >
