G-aillardia Winkleri sp. nov. 
Galllardla Yflhkleri sp* nov. Plant annual; stem usually branched above 
the base, but sometimes branched at the base or even simple, slender, 1-3 mm. in 
diameter, 30-60 cm, high, striate, canescently pubescent; branches spreading, 
teiminating in a solitsJiw, leaves oblong to elliptic, more or less acute 
at the apex and^truncate base, sessile, entire to sinuate or remotely sharp- 
serrate, the lower leaves up to 5 cm, long and 2 cm, broad, mostly saliently dentate, 
the upper leaves mostly about half that size and entire or subentire, both surfaces 
canescently pubescent; peduncles 8-20 cm, long; involucral bracts 6-9 mm. long, ovate 
to ovate-lanceolate, acute, both surfaces finely pubescent with appressed hairs; 
fimbrillae of receptacle short, conie, the receptacle short-wooly; ray-flowers 
neutral; ligules pure white, 15-20 mm, long, flabellifona, the blade up to 12 mm. 
long, 3-lobed, the lobes fully half the length of the blade and broadly spatulate, 
each lobe 3-veined with the lateral veins removed from the margin, and arching above 
to coalesce with the middle vein and there projecting as an apiculation, the blade 
itself 7-veined, the veins prominent, shortly pubescent and glandular-dotted on lower 
surface; disk yellowish-green, 1,5-2 cm, broad; disk-corollas 8-9 mm. long, or about 
2 mm, longer if the spreading lobes are straightened out, the tube about 1 mm, long, 
the lobes subulate from a broad base and about 3 mm, long, the upper two-thirds being 
strictly spreading; achenes 2 mm, long, short hirsute, the hairs not extending above 
the apex of the achene; squamellae 8, lanceolate, attenuate into an awn which is 
fully as long as the body of the scale, the scale with the awn fully equalling the 
corolla. 
This species, the only white gaillardia in North America, was ^llected 
‘Jctober 6, 1934, and again September 15, 1936, both times in the same’localit^. in 
southern Hardin County, fexas* On both occasions we were accompanied by our friend. 
l^iukler, a botanist and landscape gardener of -oeaumont, and also by two 
ladies especially interested in nature study work of women’s clubs, Mrs. Bruce Heid 
of Port Arthur and h4»s, J, L. Hooks of Beaumont, ¥/hen the opinion was expressed 
that this was a new and distinct species of Gaillardia the iadies requested that it 
be named in honor of Mr, Winkler, and I take pleasure in acting acooMiingly, 
This species is closely related to G, chrysantha Bmall, but we have 
seen that species only from considerably farther west and south, and we have not seen 
it in either of the two years we have collected plants in -^ast J-exas, This species 
G» chrysantha especially in the color of the ray-flowers and of the 
disk, and in other particulars such as in all its leases being sessile, its disk 
being larger, its |iigules and the disk-corollas being longer, and in its involucral 
bracts and achenes being shorter. It is possibly the most attractive species of 
Gaillardia in the State, 
Type specimen, No. 20067, collected September 15, 1936, about five 
miles south of Silsbee in Hardin County, ^exas, is deposited in the Gray Herbarium.
