196 LEAFLETS. 
Island of Santo Domingo, Wright, Parry & Brummel, 1871’ 
n. 261 as in U. S. Herb. The long narrow foliage of thin tex- 
ture, singularly white beneath, and the very slender scapes 
together give the plant a marked likeness to Primula farinosa. 
C. Erosa. Rather slender rootstock an inch long, ascending 
or horizontal, the fibrous roots neither large nor fleshy: leaves 
3 or 4 inches long, very thin, dark green and glabrous above, 
beneath pale with a thin but close persistent tomentum, lyrate 
lobes small, in two pairs, body of blade oval, acutish, lightly 
and coarsely crenate-lobed and the whole margin sharply erose- 
dentate: scapes several, a foot high, slender, naked ; involucre 
an inch high. of subulate-linear thin bracts: achenes small, 
slender, the slender stipe of the pappus of twice their length ; 
pappus firm and soft. 
Costa Rica, June, 1892, Conduz, n. 447 as in U. S. Herb. 
C. MICRODONTA. Large, with well developed ascending, 
rootstock : leaves 3 to 9 inches long, with broadly oblanceolate 
blade tapering to a winged petiole nearly as long, margin of all 
minutely and not at all retrorsely denticulate, upper face darker 
green or even purplish, glabrous in maturity but arachnoid- 
tomentose when young, lower face densely silvery-tomentose: scape 
not slender, 16 to20 inches high, naked, flocculent: involucre large 
its outer bracts subulate-filiform, inner narrowly-linear : achenes 
minutely hispidulous on the ribs and as minutely scaberulous 
between them ; pappus-stipe slender-filiform, 4 or 5 times the 
length of the achenes. 
Yungas, Bolivia, 1894, Miguel Bang, n. 2095 as in U. S., 
Herb., named integrifolia on the label; but Cassini’s Zeria integ- 
rifolia is of southwestern South America, and extremely differ” 
ent from this. 
C. MasuscuLA. Rootstock stout, an inch long or more: 
leaves commonly 8 or 10 inches, lyrate by several pairs of deep 
and angular small basal lobes below the very large terminal one, 
this oval to ovate-lanceolate, subcordate, lightly but distinctly 
crenate-lobed, each lobe with 2 or 3 sharp retrorse teeth, texture 
of the whole very thin, glabrous above, hoary beneath with a
