76 UNITED STATES AND MEXICAN BOUNDARY. 
卫 UPATORIUM SCHIEDEANUM, Schrad.; DC. Prodr. 5, р. 159. (E. multinerve, Benth. E. 
Schiedeanoides, Schultz, Bip.:) var. G@ROSSE-DENTATUM. E. Sonorae, Gray, Pl. Wright, 2, p. T4. 
Mountain ravine near Santa Cruz, Sonora; Wright. Lower Rio Grande, Texas, near Ringgold’s 
Barracks, etc.; Schott. The latter is a more diffuse and loosely flowered form, approaching E. 
paniculatum, Schrad., in the inflorescence, but not in the leaves. The form with dense corymbs 
which comes from southern Mexico, Costa Rica, etc., Dr. Schultz has ascertained to be Lessing’s 
E. pycnocephalum, а name not very appropriate for our forms nor for the specimens of Berlandier., 
The plant of the Rio Grande is said by Mr. Schott to exhale a moschate odor. 
卫 UPATORIUM BERLANDIERI, DC. Prodr. 5, p. 167. E. ageratifolium 8? Mexicanum, DC. 
l. c. p. 173. E. ageratifolium, var. Texense and var. herbaceum, Gray Pl. Lindh. & Pl. 
Wright. Various forms from southern Texas to the mountains near Santa Cruz, Sonora, (the 
nearly herbaceous state.) In Berlandier’s reliquie distributed by me, this occurs under the 
numbers 762 and 2182, (between Victoria and Tula,) and 756, 2176, (between Tula and 
Tampico ;) also from San Carlos, Tamaulipas, 3164. These all belong to one species, and the 
difference in the length of the pappus remarked by De Candolle is inconstant. The name of E. 
Berlandieri had best be retained for the species, at least until it is identified with the Cuban 
species. 
Evpatorium WRIGHTI, Gray, Pl. Wright, 2, p. 87. New Mexico; Wright. 
卫 UPATORIUM SOLIDAGINIFOLIUM, Gray, l. с. New Mexico; Wright, &c. 
EUPATORIUM SEROTINUM, Michx. San Pedro river, western Texas; Bigelow. 
EUPATORIUM CONYZOIDES, Vahl. Symb. З, p. 96. Lower Rio Grande; Schott. Rocky ravines, 
near Santa Rosa; Bigelow. Mr. Trecul gathered this at the mouths of the Mississippi. De 
Candolle’s Mexican stations are from Berlandier’s collections, in which it occurs under numbers 
1384, 2210, 2355, ete. The original colored drawing (in my possession) for the plate in Schrank’s 
Pl. Rar. Hort. Monac., t. 85, represents the flowers as white or whitish.* 
CONOCLINIUM cGLESTINUM, DC. Prodr. 5, р. 185. Rio Grande, near Laredo, Schott. 
CONOCLINIUM BETONICUM, DC. l. в. Lower Rio Grande, Schott. А nearly glabrous form, with 
hastate-oblong and very obtuse leaves. Also.a remarkable and doubtful form, with thin, gla- 
brous, and entire ovate leaves from near the mouth of the Pecos, Perhaps the species, which 
seems to be polymorphous, likewise includes C. Hartwegi, Walp., the Eupatorium Hartwegi, 
Benth. Pl. Hariw. 
— COoNOCLINIUM DISSECTUM, Gray, Pl. Wright, 1, p. 88. From the lower Rio Grande to the 
borders of Sonora; found by all the collectors. It is singular that this does not occur in 
Berlandier’s collection. 
MIKANIA SCANDENS, Linn. Southern Texas, Schott. «е. 
ConETHROGYNE INCANA, Nutż. (excl. syn.) San Diego, California; on hills; Parry. Probably 
this is no more than a state of C. Californica, without chaff on the receptacle, 
CoRETHROGYNE FILAGINIFOLIA, Nutt. ; Torr. & Gray, Fl. 2, p. 98. There is a great deal of 
confusion in the description and synonymy of this and С. tomentella in the Flora of North :

© EvPATORIUM AZUREUM, DC. l. c. p. 168, No. 1380 of Berlandier's colletion, was also gathered by Dr. Gregg at Monterey, 
in better specimens. The heads are 30—40-flowered ; the corolla purplish, according to Gregg; and the leaves are 
broadly deltoid. The species is allied to E. deltoideum, but the leaves are not hastate, the heads are shorter and smaller, 
the involucre more biseriate, its outermost scales broader, and the achenia nearly glabrous.
