NEW OR NOTEWORTHY SPECIES. 983 
irregularly toothed or slightly lobed and usually with a row 
of purple spots across the basal part of the lamina: pedicels 
very slender, far exceeding the leaves: calyx-teeth unequal, 
the uppermost of the five much the largest: corolla strongly 
bilabiate, 3—1 inch long, yellow, with purple dots. 
Gravelly margins of mountain streams in Lake County, 
California, August, 1888. Most related to M. laciniatus of 
the Sierra Nevada; the calyx like that of M. nasutus. 
NAVARRETIA LEPTANTHa. Near N. atractyloides and as 
large, but slender and rather diffuse, viscid puberulent and 
heavy-scented : leaves with a lanceolate rachis and spinose- 
subulate very rigid segments in 3—5 pairs: segments of the 
calyx erect, spinose-subulate, entire, 2 twice as large as the 
others: corolla deep purple, salverform, the tube almost fili- 
form and more than a half-inch long. —N. hamata in part, of 
page 159, 
Collected at All Saints Bay, Lower California, by the writer, 
in 1885; also a year later, in the same locality, by C. R. Orcutt. 
Having taken but a single specimen, I placed it under N. 
hamata at the time of writing the earlier article upon 
Navarretia ; but I did so with much reluctance, on account 
of the large corollas with greatly elongated tube. Mr. Orcutt’s 
specimens confirm the plant as a distinct species. 
SERICOGARPUS TOMENTELLUS. Two or three feet high, the 
inflorescence and lower face of leaves tomentulose: leaves 
coriaceous, an inch long or more, oblong or oblong-lanceolate, 
acute, entire, closely sessile by a broad base, spreading or 
deflexed, indistinctly feather-veined : heads paniculate, a half- 
inch high; scales of the hoary-tomentose turbinate involucre 
narrowly oblong, acute : rays none; achenes sparingly villous ; 
pappus dull or tawny. 
Coast Mountains, near Waldo, Oregon, J uly, 1888, Thomas 
Howell. A quite remarkable plant, in which there ia a blending 
of some characteristics of Machcranthera and of Corethro- 
gyne, with those of the genus to which it undoubtedly belongs.
