pedunculate, about 1 cm. high, 1.5 to 2 cm. broad, terminating the stem 
and branches and either solitary or in few-headed paniculate-cymes + 
outer involucral bracts few, herbaceous, slightly spreading ; inner bracts 
of the involucre oblong, 6 mm, long, 2 to 2.5 mm. broad, obtuse : ray- 
flowers few, five or six, fertile; rays with a short sparingly pubescent 
tube and a broad-oblong expanded portion, 6 mm. long and nearly as 
broad: disk-flowers about 12; achenes, as well as those of the ray- 
flowers, oblong, strongly obcompressed, destitute of pappus, glabrous. —

: In habit Coreopsis cuneifolia suggests CO. petrophiloides, Rob. & 
Greenm., from which it is amply distinct in the character of the : 
foliage, the pubescent branches, and in the glabrous epappose achenes. 
In the technical characters of the head C. cunetfolia is more nearly si, 
lated to C. mexicana, Hemsl. (Hlectra mexicana, DC.), but is readily 
separated by the cuneate or oblanceolate-cuneate leaves, by the pubescent 
branchlets, ete. 
LEPTOSYNE ARIzZONICA, Gray, var. filiformis, n. var. Glabrous: 
throughout ; leaves 3-5-parted; segments filiform, 8 cm. or less ™ 
length.— Mexico. State of Sinaloa: Sierra de Choix, 80 km. N. E. 
of Choix, 15 October, 1898, Z. A. Goldman, no. 258 (hb. Gr. and 
hb. U. S. Nat. Mus.). Aside from the filiform attenuated leaf-segments 
ho important characters are observed separating the variety from ty pical 
_ representatives of the species. 
LePTosyne prnnata, Rob., var. integrifolia, n. var. Leaves 
simple, undivided, entire or crenulate: pappus evident, coroniform, often 
of several short unequal more or less lacerated scales. — Mexico. State é 
of Durango: near el Salto, 12 July, 1898, E. W. Nelson, no. 4580. — 
Mr. Nelson’s plant at first glance seems very different from the typ& 
specimen of Leptosyne pinnata ; but aside from the characters enumel 
oe = ated, namely, the entirety of the leaves and the fairly well developed 
pappus, there are no further differences. a 
Bivens Lupens, Gray, Proc. Am. Acad. xxi. 390. This spectes 
was founded on Pringle’s no. 293 collected on hills and plains near the 
City of Chihuahua, Mexico, in October of 1885. The printed label acx 
companying this plant in the Gray Herbarium bears the name “ Leptosyn@ 
Arizonicus, Gray.” The unfortunate confusion of names probably : 
Tesulted either in reporting the collection or in printing the labels. The
