NEW SPECIES OF CONVOLVULUS. 327 
the same subterranean growth; the stems only a few inches 
long, shorter than the very long petioles of the tufted leaves: 
leaf-outline more reniform-hastate than in the last, the hoary 
pubescence truly tomentose rather than velvety, the leaves 
remarkably veiny: bracts at base of flower twice as long as 
the calyx, the outer sepals pubescent up and down the mid- 
dle portion only: corolla narrower and longer than in the 
preceding 
Dry foothills of the Coast Range, in open ground at mid- 
dle elevations. Very distinct from C. malacophyllus. 
C. NYCTAGINEUS. Of the size of C. malacophyllus, and with 
the same underground growth, but the plant glabrous: 
leaves larger, of broadly ovate-trigonous outline, abruptly 
acute at apex, and with or without a distinct small hastate 
lobe on either side near the somewhat cuneately tapering 
base: flowers few, all in the axils of the lowest leaves; in- 
volucral bracts very thin, oval, obtuse or almost truncate, 
barely equalling the obtuse and mucronate sepals; corolla 
large, apparently pinkish. 
An Oregonian species, known only in specimens distrib- 
uted in 1882, by Mr. Howell, and under the name C. Cali- 
fornicus ; which last (C. subacaulis, Greene, Man., p. 265) is a 
low almost stemless pubescent plant, with very different 
floral characters. 
C. TOMENTELLUS. Rhizomatous, the slender stems solitary, 
prostrate or reclining, a foot long or less, very leafy with 
small short-petioled foliage, the few flowers from the axils of 
the lowest leaves; the whole plant cinereous with villous- 
tomentose pubescence: the sharply triangular-hastate leaves 
about $ inch long, and as broad, obviously 3-lobed, the diver- 
gent basal lobes well differentiated from, and approaching 
. the size of, the body of the leaf: small cream-colored flowers 
short-peduncled; bracts closely subtending the calyx, oblong
