146 COMPOSITiE. Aster. 



73. A. multiceps (Lindl.) : glandular-pubescent throughout; stem race- 

 mose ; the branches erect, bearing single heads ; leaves oblong-linear, acute, 

 pubescent, slightly scabrous; scales of the involucre linear, subulate, whitish 

 at the base, squarrose. Lindl. in DC. prodr. 5. p. 237. 



Louisiana. — A very distinct species, not closel}' allied to any one known ; 

 perhaps of the Amelli section, if the inner scales of the involucre were mem- 

 branaceous and colored. Liiull. — We know not from whom this species 

 was derived. It is placed at the end of the section which includes A. puni- 

 ceus, prsealtus, &c. 



74. A. suhspicatus (Nees) : stem hairy in lines ; the branches virgate ; the 

 branchlets hirsute, bearing the heads somewhat in s])ikes ; leaves oblong- 

 lanceolate, acute, appressed -serrate, glabrous, with scabrous margins, clasp- 

 ing; scales of the involucre somewhat equal, lax; the exterior spatulate- 

 lanceolate, broader. Nees, Ast. p. 75; DC. prodr. 5. p. 237. 



Mulgrave Promontory, on the North West Coast of America. {Nees.) — 

 Heads of the size and form of those of A. oblicjuus, 3-7 upon each branchlet, 

 nearly sessile (on hirsute pedicels scarcely half a line long) in the axils of 

 the upper leaves, approximate, solitary, or 2 to 3 on the highest branchlets. 

 Involucre as long as the disk, erect, loose ; the scales in several series; the 

 inner linear-lanceolate, mucronate-acute, ciliate ; the bose membranaceo- 

 chartaceous, pale, with a green nerve which is lanceolate-dilated upwards. 

 Rays numerous, lanceolate, purplish ; the disk-flowers turning rose-color : 

 'stigmas short, dimidiate-conic, scabrous.' Aclienia small, obconic, densely 

 canescent-strigulose. Pappus brownish. Nees. — It is placed in the same 

 section with A. Novi-Belgii, &c. 



75. A. tknc^us (Pursh) : stem pyramidate-branched; the branches axil- 

 lary, scarcely longer than the leaves, bearing the heads in racemes; pedun- 

 cles tomentose, naked ; leaves oblong-lanceolate, partly clasping, acuminate, 

 serrate, glabrous ; scales of the involucre lax, somewhat equal, shorter than 

 the disk. Pursh, fi. 2. p. 555 ; DC prodr. 5. p. 237. 



Canada, Herh. Banks. U Oct.-Nov. Flowers above the middle size : 

 rays pale purple. Pursh. — Nothing farther is known respecting this species. 

 The A. blandus, Lodd. hot. cab. t. 959 (perhaps A. puniceus?) is doubtless 

 different from Pursh's plant. 



76. A. hehecladus (DC.) : stem slightly shrubby, slender, hirsute with a 

 close spreading pubescence ; branches loose, leafy, with few branchlets 

 bearing single heads ; leaves sessile, Hnear, entire, mucronate-acute, both 

 sides villose-scabrous ; the u])permost ciliate ; scales of the involucre loosely 

 imbricated, linear, puberulent, acute. DC. prodr. 5. p. 242. 



Texas, in the eastern districts, Berlandier. — Allied to A. scoparius, but 

 with looser hirsute branches, bearing few heads about one-third the size. DC. 



77. A. scoparius (DC) : stem slightly shrubby, erect, much branched, 

 glabrous, scarcely puberulent at the summu ; branches erect, racemose ; leaves 

 sessile, hnear, minutely scabrous, the upper ones ciliate ; branchlets leafy ; 

 scales of the involucre loosely imbricated, Hnear, acute, ciliate. DC. pro'dr. 

 5. !>■ 242. 



Texas, in the eastern districts, Berlandier. — Plant with nearly the habit of 

 Erica scoparia. Leaves 4-5 lines long, half a line wide. Pappus reddish- 

 brown. Achenia puberulent. DC. — This and the preceding are placed in 

 the same section with A. ericoides, A. dumosus, &c. 



78. A. bifrons (Lindl.) : stem scabrous, lax, racemose ; branches race- 

 mose at the summit ; leaves oval-lanceolate, scabrous above, nearly all ser- 

 rate ; heads secund ; scales of the involucre subulate. ^^ Nees in litt. ad 

 Lindl:' ; DC. p>rodr. 5. p. 243. 



North America. — Allied to A. pendulus ; distinguished by the branches
