ADDITIONS AND CORRECTIONS 605 



ivnighlsh with short cinerous closely appressed hairs. Leaves 3 fourths of an inch 

 to 2 inches long, and 1 fourth to 2 thirds of an inch wide, varying from lanceolate 

 to cuneate-obovate, mostly rather acute, coarsely serrate above the middle, entire 

 below the middle, and more or less cuneately tapering to a very short petiole, 

 roughish (like the stem and peduncles) with appressed hairs (glabrous, Ell.). 

 Flowers Closely imbricated with bracts, in small roundish-ovoid er conical head*, 

 on solitary axillary peduncles 1 to 3 or 4 inches in length. Bracts roughish (like 

 the leaves) with short appressed hairs, yellowish-green, with membranaceous and 

 purple margins, the lower ones broad-ovate, the others fhomboid-cuneate, abruptly 

 acute, and minutely denticulate nearthe summit. Calyx much smaller than the 

 bracts, membranaceous, obcompressed, deeply and sinuately 2-parted, or perhaps 

 composed of 2 lanceolate acuminate conduplicate sepals, which are ciliate on the 

 keel, or back of the duplicature, at each margin. Corolla bluish or purplish- 

 white, the tube about as long as the bracts, the limb somewhat bi-labiate, the 

 upper lip small, emarginate and mostly reflexed, the lower one 3-lobcd.

 Obs. Collected in Aug. 1836, by Mr. Joseph Rinehart. Authors, generally, 

 describe the calyx as u 5-toothed ;" but I find the description of the faithful and la- 

 mented Elliott to be much more accurate. The Z. lanceolata, of the books, is pro- 

 bably nothing more than a variety of this,— and if so, this is the only known species 

 in the U. States, if not of the genus.

Flant smooth and remarkably glaucous. Root annual, mostly fusiform, and giving 

 out fibres. Stem 12 to 18 inches high, erect, striatc-angled, branching. Leaves 

 peliolate, somewhat biternately dissected, the primary divisions petiolate, tho 

 secondary ones sub-petiolate, deeply 2 or 3-partcd, the subdivisions cuneate, 2 or
