 T. micrantha, Cat. Slender, diffusely much branched, Anise-scented, a span to a foot 

 high from an annual root, with loosely paniculate slender-peduncled heads : leaves linear- 

 filiform, 3-5-parted, or some of the lowest undivided, not serrate : involucre fusiform, about 

 half-inch long, few-flowered ; rays 1 to 3, the oval pale yellow or white ligules only a line 

 long : akenes slender, glabrate, longer than the pappus of 2 oval or truncate thin paleae and 

 2 longer awns. — Ic. iv. 31, t. 352 ; DC. Prodr. v. 646 ; Gray, PI. Wright, ii. 93. — Dry ground,

169. PfiCTIS, L. (ITeKTeci), to comb, the leaves of most species of the 

 genus pectinately setiferous. It is an ancient Latin name of some plant, appro- 

 priated to this genus by Linnaeus.) — Herbs, all American, mostly low and spread- 

 ing, usually glabrous, heavy-scented ; with narrow opposite leaves conspicuously 

 dotted with round oil-glands ; and with mediocre or small heads of yellow flowers, 

 occasionally turning purplish, slender rigid bristles fringing at least the base of 

 the leaves, or rarely quite wanting. 



§ 1. Eupectis. Pappus of a few paleae or slender awns with or without a 

 dilated or chaffy base, or in some (and occasionally in all) of the akenes reduced 

 to a paleaceous crown, or to a few squamellas, or obsolete : base of the leaves 

 copiously setiferous. — Gray, Proc. Am. Acad. xix. 44. Pedis § Pectidopsis & 

 Eupectis, Gray, PL Wright, i. 83. Pectidopsis, Pedis (excl. spec), and part of 

 Lorentea, DC. Prodr. v. 98-101. 



* Pappus paleaceous, conspicuous: the paleae (in ours 4 or 5 or 6 in the disk, 2 or 3 in the ray) 

 mostly prolonged into awns or subulate points : bracts of involucre 4 to 6, broad or broadisb : 

 ours annuals. 



P. prostrata, Cav. Procumbent or prostate : leaves oblanceolate or spatulate-linear (sel- 

 dom inch long) : heads sessile or nearly so : disk-flowers 5 or 6 : palesB of the pappus ovate- 

 lanceolate or narrower, thin, often unequal, short-awned. — Ic. t. 324; DC. Prodr. v. 100;

 (Mex., W. Ind.?) 



P. ciliaris, L. Erect or diffuse, sometimes a foot high : leaves linear-oblanceolate or nar- 

 rower, commonly inch long : heads nearly sessile : disk-flowers 4 to 8 : paleae of the pappus 

 lanceolate-subulate tapering into a slender awn, more rigid and equal than in the preceding.

P. linif 61ia, Less. Erect, diffusely branched, slender, a span to a foot high : leaves narrowly 

 linear, inch long : heads on minutely bracteate filiform (commonly inch long) peduncles : 

 involucre (2 lines long) of narrower bracts : palese of the pappus ovate or ovate-lanceolate, 

 abruptly long-awned, or some nearly awnless. Varies with peduncles not longer than the 

 head. — Less, in Linnaea, vi. 709 (excl. syn.) ; DC. 1. c. 99 (excl. syn.) ; Griseb. F. Brit. W.

# # Pappus pauciaristate ; viz. of 1 to 5 or 6 upwardly scabrous (usually slender and setiform 

 but rigid) awns, at most dilated only at very base, with or without a short chaffy crown of con- 

 nate or separate squamellse, sometimes reduced to this, the awns being absent: bracts of the 

 short-cylindraceous rather many-flowered involucre linear, at length with involute margins 

 partly surrounding outer akenes: low and much branched annuals, with slender narrow-linear 

 leaves, bearing a few bristles next the base. 



-K- Heads subsessile or short-peduncled, more or less fastigiate or cymose at the end of the branches : 

 bracts of the involucre about 8. 



P. tenella, DC. A span or more high : pappus of 3 to 6 slender awns, not much shorter than 

 the akene : no squamella? or crown. — Prodr. v. 99 ; Gray, Bot. Mex. Bound. 73. — S. Texas, 

 Berlandier, Thurber, Havard. (Adj. Mex.) 



P. angustifolia, Torr. A span or two high, lemon-scented : pappus a crown of 4 or 5 

 mostly connate squamellae, and not rarely one or sometimes two slender usually short awns
