100 PITTONIA. 
flowers small, of a deep rather greenish yellow ; petals acute, 
the blade elliptical, the claw short and ligulate, the 5 inner 
ones about three-fourths as long as the 5 outer; style exserted 
beyond the numerous stamens: capsule thick-walled, not 
striate: seeds oval, flattened, yet irregularly angular on the 
face, encircled by a narrow thin margin. 
In wet strongly alkaline soil near Cafion City, Colorado, 
7 Sept., 1896. A very peculiar species, in view of the green- 
ish hue of the flowers, and the scarcely definable character 
of the seeds. 
COLEOSANTHUS SCABER. Allied to C. microphyllus, but 
neither villous nor viscid, merely scabrous-puberulent and 
slightly glandular: slender woody branches leafy below, 
racemose from below the middle: leaves broadly ovate, 
coarsely toothed, deflexed on the very short petioles, the 
largest $ inch long, those of the monocephalous (or rarely . 
tricephalous) peduncles greatly reduced ; bracts of the invo- 
luere obtuse or acutish; flowers about 10 or 12 to the head: 
&chenes serrulate-scabrous on the angles. 
Mountains near Grand Junction, Colorado, 27 August, 
1896. In addition to my own specimens I have seen one 
rather poor one in the herbarium of the Smithsonian Insti- 
tution, this from the Mesa Verde, in southeastern Colorado, 
collected by Miss Eastwood. It was referred to C. mier a 
phyllus. I also suspect, from the account given of “ B. mt 
crophylla” in the Synoptical Flora, that Dr. Gray had the 
present plant, and that his attempted description of N uttall’s 
Oregonian species is modified and extended to cover this 
entirely too dissimilar one. 
SOLIDAGO TRINERVATA. Stemsdecumbent and ascending, | 
from branching and widely spreading horizontal rootstocks: —— 
herbage cinereous-scabrous: leaves widely spreading on the 
stems, linear-lanceolate, entire, very acute, many of them 
distinetly triple-nerved, mostly 2 or 3 inches long: panicle P
