Gccalia atriplicifolia L,, var. texana var. nov. Plant perennial, 
glabrous, glaucous; stem 1 m. high or more, strict, terete, not grooved, branching 
only at the top in the inflorescence; leaves alternate, glaucous on both surfaces, 
digitately 5-veined, the 3 inner veins j>jrominent, acute at both ends, angulately- 
toothed, short-petiolate; cauline leaves up to 10 cm. long and 2.5 cm. broad, 
broadest just above the middle; petioles short, stout, mostly 1 cm. long or less, 
dilated and clasping at the base; basal leaves not present in our material; 
inflorescence of coryiabose clusters, the lowest branch 15 cm. long or more and the 
others progressively shorter, eract-ascending; heads numerous, pedunculate; 
peduncles slender, 1 cm. long or more and up to 2 cm. long; involucres cylindric, 
of one row of 5 bracts; involucral bracts oblong, 10 mm. long, 3 mm..broad, 
scarious-margined, obtusish, thickenad^^t.the base, ecalyculate; receptacle v/ith 
a scale-like appendage in the center^^^e^nish, as bread at the truncate apex as 
at the base, 1 mm. high, 1 mm. broad, 3-ridged on one face, plane on the other 
face, the apex 3-toothed; achenes cylindric, 5 mm. long, .7-.8 mm. broad, slightly

Type specimen, No. 19824, was collected September 13, 1936, in North¬ 
western Hardin County, Texas, about ten miles east and north of Votaw. It is 
closely related to C. atriplicifolia, differing in that the leaves are narrower 
and are not palmately-veined and not angularly-lobed nor incised. Possibly more 
inforraation might indicate the desirabiily of considering this as a distinct 
species, rather than as a geographic variety of C. atriplicifolia, as is here 
done. This plant likely occurs throughout the Big Thicket area of Southwestern 
Texas.
