wide, narrowed below to short petioles: cymes few-headed, scarcely 
or not at all exceeding the upper leaves: pedicels 3-1 inch in — 
length, pubescent: heads discoid, orange-yellow, 5 lines high, about : 
12-flowered: * bracts of the involucre about 10, the outer oblong or | 
spatulate, obtuse, scarcely half the length of the flowers, the inner ~ 
more or less. acute: corolla hispidulous upon the outer surface: 
achenes black, with broad wings and two nearly erect awns: heads 
of fruit subglobose: the plicate chaff with bright yellow curved tips 
exceeding the achenes. — Dry rocky bluffs of barranca near Guada- 
lajara, September, 1891 (n. 3845). This species differs from V. se” 
rata, Cav., in its shrubby habit, narrower leaves, somewhat smoother 
stem, ete. Berlandier’s no. 1289, collected at Monte San Juan del — 
Rio, November, 1827, is evidently nearly related to Mr. Pringle’s — 
plant, but the specimen is too fragmentary for certain identifica — 
tion; there appear to be slight differences in the achenes, and the — 
heads of Berlandier’s plant do not have the chaff conspicuously _ 
curled in fruit. 
Sprmantues Beccasunea, DC., var. PARVULA. Root a cluster — 
of thickened fibres: stems several, decumbent, 4-6 inches high, 
rooting at the lower joints: leaves ovate, entire, including petiole : 
only 6-10 lines long, half as broad: heads a little smaller and rays — 
shorter than in the typical form: anthers dark, slightly caudate = 
the base. — Wet soil, Flor de Maria, State of Mexico, Au 
1890 (n. 3643). This may perhaps be a distinct species. 
SPILANTHES DISCIFORMIs. Stem prostrate, woody, verrncoses : 
rooting at the joints, and.sending up numerous subsimple, more OF 
less fleshy, glabrous, purplish branches: leaves lance-oblong or lance 
linear, triply-nerved, entire, glabrous, 10-14 lines long, 1}-8 lines 
wide, usually considerably exceeding the internodes, narrowed to — 
blunt point, contracted below to.a short, sometimes ciliated petiole: 
peduncles at the ends of the branches, striate, glabrous, 2 inches — 
long: seales of the involucre ovate (not lanceolate nor oblong)y “ 
acute, subciliate: rays yellow, inconspicuous, scarcely exce ing 
the involucre, the heads at first sight thus appearing discoid: 7 
ceptacle much elevated: disk flowers yellow: anthers entire at the 
base: achenes black, ciliate at the angles, and slightly hispid 02 — 
the faces, exaristate. — Wet meadows, near Guadalajara, May, : 
1890 (n. 3489). A stout, somewhat fleshy species, differing 
S. Beccabunga in its more woody stem, narrower entire leavetr 3 
ae shorter rays, ovate scales, and entire anthers.
