 T. micrantlia, CAV. Slender, diffusely much branched, Anise-scented, a span to a foot 

 lii'i-h from an annual root, with loosely paniculate sleuder-peduncled heads: leaves linear- 

 nlfform, 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 : akeues slender, glabrate, longer than the pappus of 2 oval or truncate tliiu palerc and 

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

169. PECTIS, L. (LTeKreo), 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 paleac 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 squamellag, or obsolete : base of the leaves 

 copiously setiferous. Gray, Proc. Am. Acad. xix. 44. Pectis Pectidopsis & 

 Eitpectis, Gray, PL Wright, i. 83. Pectidopsis, Pectis (excl. spec.), and part of 

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



* Pappus paleaceous, conspicuous: the palere (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 G, broad or broadish : 

 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 : palese of the pappus ovate- 

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

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 : palese 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: paleaj of the pappus ovate or ovate-lanceolate, 

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

 head. Less, in Linnsea, 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 b:ise, witli or without a short chaffy crown of con- 

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

 sbort-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. 



H 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 akeue : no squamellaj or crown. Prodr. v. 99 ; Gray, Bot. Mex. Bound. 73. S. Texas,
