160 BOTANY. 
gated, naked, and terminated by a single head 14-2” in diameter ; involucre 
with scales in about four series, all distinctly nerved, the outer ovate, obtuse, 
the inner lanceolate, acute; ligules persistent (fading away into a pale 
sulphur color), 2—3-toothed at the apex ; achenium (ray) 3-angled, rounded, 
and papillose on the outer side; disk-flowers narrowly tubular; achenia 
4-angled; chaff hardly as long as the flower—Chiricahua Agency, Southern 
Arizona (536). My specimens are apparently much larger-flowered than 
those of Mr. Wright, on which the species was founded. betes came, 
however, from near his locality. 
GYMNOLOMIA * MULTIFLORA, Benth. & Hook. (Heliomeris multiflora, 
Nutt.)—A very variable plant. Nevada, Arizona, Utah, Colorado (779,

Ruppeckia LacintaTa, L.—(171 of Loew.) — de Cristo Pass, 
Colorado. 
RupDBECKIA COLUMNARIS, Pursh, var. PULCHERRIMA. (Lepachys columnaris, 
T. & G., 4. pulcherrima, Don.)—Erect, simple, or branching from the base, 
strigose-pubescent ; earliest leaves lanceolate and entire; stem-leaves pin- 
nately parted, with linear divisions, petioled ; upper ones similar, but sessile ; 
disk columnar, 9-15” long and 4” wide; ray-flowers dark purple, reflexed, 6” 
long and 4” wide.—Zuni Village (159), and also collected by Dr. Oscar 
Loew in White Mountains of Arizona. 
Var. Tacetes. (Lepachys columnaris, var. Tagetes, Gray, Pl. Wright. 1, 
p- 106.)—Similar to the above except in having small yellow or brown rays 
and a shorter disk. Arkansas Valley, Colorado (24, Loew); Valley of the 
Rio Grande, above Albuquerque (85). 
RupBeckiA uirta, L. (apparently)—Trout Creek, Colorado (549, 550). 
RUDBECKIA OCCIDENTALIS, Nutt.—Utah. 
BALSAMORHIZA SAGITTATA, Nutt—Northern Nevada and Utah. 
* GYMNOLOMIA, H. B. et K.—Heads heterogmpous, radiate; rays ps i BOUSERE; disk-flowers per- 
fect, fertile. Involucre hemispherical or broadly campanulate; bracts in 2-3 series 
@ little shorter, interior thinner, all narrow, or rarely with the exterior or interior enlarged. Receptacle 
convex or conical; chaff concave and embracing the disk-flowers. Ray-flowers ligulate, rat tie 
entire or dentate. Disk-flowers regular; tube short or with a somewhat dilated base. Anthers entire 
at base or with two small auricles. Styles of the disk-flowers obtuse or sometimes eet by 
a short, acute appendage. Achenia of the ray-flowers narrow, empty; of disk-flowers sub-compressed, 
4-angled, obtuse at apex (in our species destitute of pappus) — Erect, branching herbs.—BenTH. & 
Hook, .
