puberulent beneath, the margins more conspicuously woolly- 
eiliolate: scapes 2 feet high or more, often with a bract at 
some distance below the head: involucre an inch high and 
nearly as broad, of 40 or 50 closely imbricated bracts, the 
outer half of them foliaceous, ovate, with acute spreading 
tips, the inner lanceolate to linear-lanceolate, membranaceous, 
erect: ligules large and showy : akenes 2 lines long, tapering 
into the filiform stipe of the pappus which is a half-inch in 
length. 
Meadow lands of the southern part of Humboldt County, 
California, 1887, Mr. C. C. Marshall. The largest known

leafy involucral bracts. 
PHACELIA RUGULOSA, Lemmon in herb. Annual, 6 inches 
high, puberulent and very viscid: leaves mainly radical, 2

segments as broad as long: racemes terminal, slender, elon- 
gated, on sparingly leafy peduncles: corolla minute, bluish : 
stamens not exserted : fruiting calyx 2 lines long, the segments

the elliptical transversely rugulose capsule : seeds about 30, 
oblong, + line long, encircled by deep and closely connected 
foveolations, and intermediate sharp ridges. 
Lower California, May, 1888, Mr. Lemmon. A species 
which seems to break down the division between the Micro- 
genetes and other sections of Phacelia. 
PHACELIA LEUCANTHA, Lemmon in herb. Annual, viscid- 
pubescent, near the last but taller, a foot or two high, the 
racemes panicled: leaves lanceolate, pinnatifid, the linear-

racemes ternate, rather dense: corolla-limb rotate, nearly an 
inch broad, clear white, the short throat and tube yellow; 
stamens very short: calyx 3—4 lines long, the linear-spatulate
