EuPATORiUM Parryi (sp. nov) : glanduloso-hirsutum, ramosum ; foHis alternis nunc cppo- 

 sitis cordatis acutis grosse inciso-crenatis raembranaceis subtriplinerviis veuosiM ; petiole elongato 

 marginato ; corymbis circiter 5-cephalis ; pedunculis gracilibus ; capitulis circiter 20-floris cylin- 

 draceis, squamis inibricatis triseriatis lanceolatis striatis aristato-acuminatis extus pubescenti- 

 bus; acheniis ad angulos hirtellis. — Sierra de Carmel, near the Eio Grande, Chihuahua; 

 October ; Parry. Branches of an herbaceous species, apparently of a diffuse habit, which has 

 the involucre and habit of a BrichelUa (but the achenia are pentangular without intermediate 

 striae,) or of an OocUnium^ but the receptacle is flat. Leaves about an inch in length and 

 breadth, deltoid-cordate, beset with a sparse and short pubescense or glabrate. Petioles 6 to 8 

 lines long, with narrow decurrent margins, hirsute with glandular or viscid hairs, like the 

 stem, peduncles, etc. Peduncles minutely bracteolate. Heads half an inch long. Scales of 

 the involucre green, lucid, appressed, strongly striate, tapering, especially the inner ones, into 

 a slender short awn. Flowers apparently ochroleucous. Achenia 2 linea long, with a con- 

 spicuous basilar callus, slender. Pappus white^ scabrous* 



EuPATORitJM BiGELOVii (sp. uov) : cinereo-pubesccns, ramosum ; foliis oppositis ovato- 

 lanceolatis acutis integerrimis breviter petiolatia a basi rotundata tri-q^uinquenervatis supra 

 glabratis subtus tomentosis ; capitulis ternis quinisve ad apicem ramulosum brevi-pedicellatis 

 20-30-floris ; involucro turbinato cinereo-tomentoso ; squamis pluriseriatim imbricatis striatis, 

 acutis, exterioribus ovatis oblongisve, interioribus lanceolatis seu linearibus purpurascentibus ; 

 acheniis secus angulos scabridis. — On the Gila, Sonora ; Parry. Apparently an upright herba- 

 ceous plant, also with much the aspect of a Brickellia, but with the characters of Eupatorium. 

 Leaves 2 or 3 inches long, thin, the larger an inch or more in width near the base, thence 

 tapering to an acute point. Petioles 3 lines long. Heads half an inch long. Scales of the 



turbinate and tomentose involucre rather loosely imbricated in 5 or 6 series, the exterior 

 successively shorter and broader. Flowers purplish. Pappus tinged with purple or brownish. 

 Achenia a line and a half loncj.*

139, since it has pentagonal achenia and is a true Eupatorium. The species is founded on Berlandier^s Nos. 764 and 2184 

 (Amer. distrib.) JIj specimens have only upper leaves, few of which are much hastate.
