142 BOTANY. 
this species, I can recognize var. hispida, Gray, which is best marked, with 
its leaves lanceolate and acute, or spatulate, oblong and obtuse, from 3-1’ 
long; plant hispid, with short, stiffish, and more or less dense hairs. (555, 
464, from Colorado, 792 from Arizona, and an unnumbered one collected by 
Loew in New Mexico; var. foliosa, Watson, more leafy, with leaves obovate- 
spatulate, 1’ long, and more or less canescent, running into C. canescens, T. 
& G. (791, 182, from Arizona, and 552 from Colorado). Canescent form 
(724) from Southern Arizona is well marked.) 
Var. Rurrerr.—Stem erect, densely leafy; leaves 1-14’ long, lanceolate, 
acute, densely covered with long, white, silky hairs; leaves gradually reduced 
to bracts under the involucre; ray-flowers 3’ long, 1-14” wide-—Sanoita 
Valley, Arizona (662). This may be reduced to C. villosa var. canescens, 
which is apparently its nearest ally, yet it is quite different from any speci- 
mens of the latter that I have in my collection. 
Aptopappus* Macronema, Gray (Proc. Amer. Acad. 6, p. 542).—Twin 
Lakes, Colorado, 9-10,000 feet altitude (451). 
‘‘APLOPAPPUS CERVINUS, Watson (Amer. Naturalist, 7, p. 301).—Low 
(6 inches high), suffruticose, resinous-scabrous, the short herbaceous stems 
leafy to the top; leaves oblong-lanceolate, 4-6” long, shortly cuspidate, 
attenuate to the base, entire, sub-scabrous, 3-nerved; heads 3-4’ long, in 
corymbs of 3-5, terminating the branches; outer involucral scales. linear, 
acuminate, with setaceous, spreading tips, the inner chartaceous, acutish, 
with scarious, lacerated margins, erect, nearly equalling the pappus; rays 
few, narrow, and but little exceeding the disk; style exserted; achenia 
linear, pubescent—Nearest to A. suffruticosus, Gray, Antelope Cation.” 
Utah.—Warsoy, J. c—Puare VI. 1. Branch, natural size 2. Inner invo- 
lucral scale. 3. Outer involucral scale. 4. Disk-flower. 5. Style and 
stigma. 6. Anther. All except the branch enlarged. 
Aptopappus Fremonti, Gray (Jour. Bost. Nat. Hist. Soc. v. 5).— 
Glabrous, 1° high; corymbosely branched above, with the leafy branches 
* APLOPAPPUS, Cass.—Heads several- to many-flowered, heterogamous with fertile rays, or homo 
gamous and destitute of rays. Involucre imbricated, in 2-several rows; scales with mostly acute and 
often somewhat spreading tips. Receptacle flat or nearly so, foveolate or alveolate. Appendages of the 
style usually elongated-subulate. Achenia variable in shape. Pappus simple, of copious, unequal, rigid, 
capillary bristles, which are more or less rough.—Herbs or under-shrubs, with yellow flowers, and 
pappus tawny or reddish, not often white.—(After Gray, Fl. Cal. vol. 1, p. 310.)
