170 BOTANY. 
TaGETES* micRanTHA, Cav.—Annual, smooth, 2-6’ high; stem simple 
or nearly so; leaves opposite, entire and filiform or pinnately parted, and 
the divisions filiform; flowers terminal; scales of the involucre in a single 
series somewhat united at base, abruptly truncate and sometimes bristle- 
tipped; rays white, 1-3 in a head, 1-2’ long, entire or slightly denticulate ; 
disk-flowers about 5; pappus of two rough awns nearly as long as the 
distinctly striate linear achenia, and of 2-3 scales half as long as the awns, 
which they sometimes enclose.—Sanoita Valley, Southern Arizona, on 
rocky hillsides (616). 
Prctist FILIPES, Gray.—Annual, much branched; leaves smooth, 
narrowly linear, 12-18’ long, less than 1’ wide, with numerous glands, 
2-3 bristles on either side at base; peduncles capillary, more than an inch 
long; involucre of five lanceolate scales, with more or less scarious margins, 
frequently gland-bearing; rays exserted half their length, not more’ in 
number than the disk-flowers (5); disk-flowers half as long as the rays; 
achenia linear, hairy ; pappus usually of two stiffish awns, which are some- 
what thickened at base and slightly scabrous above, or occasionally reduced 
to one awn and a crown of minute scales. An exceedingly variable species, 
which Bentham and Hooker, in Gen. Plant., have assigned to the older P. 
Laliscana, Hook. & Arn. I can see no warrant for this, if the description 
in Bot. Beechey be correct. It should, however, be stated that the plant 
appears there to have been described from imperfect material, and more 
ETES, Linn.—Heads heterogamous, radiate ; ray- and disk-flowers both fertile, or heads some- 
times homogamous, the rays being absent. Involucre cylindrical, the bracts 1-seried and more or less 
united, rarely a single small exterior bract.is present. Receptacle flat, often small, naked or somewhat 
alveolate-fimbrillate. Ray-corolla ligulate; disk-flowers perfect ‘and bsiasepsig ‘regular, tubnlar, ~ limb 
often enlarged, 5-cleft. Anthers at base obtuse,entire. Style-1 truncate, 
penicillate or short appendicnlate. Kehoata linear, attenuate at base, compressed or angled, hasty 
striate, with a (notewhat] conspicuous callosity at base. Pappus variable [in our species, micrantha, of 
2awns and 2-3 shorter scales ].—Erect, branching or diffuse glabrous herbs, with the leaves and involucre 
having distinct, strongly scented glands.—BEnTH. & Hook. 
t PE , Linn.—Heads heterogamous, radiate; ray-flowers in a single series and fertile, as the 
disk-flowers sins Involucre cylindrical or campanulate, the free, equal bracts ina single series. Recep- 
tacle small, naked. Rays with a small or narrow blade, spreading, entire or 3-toothed; disk-flowers 
perfect, the ampliate ab short, equally or unequally 5-cleft. Anthers obtuse, sub-entire at the base. 
Styles of the disk flowers elongated, slender, somewhat hairy, with very short, obtuse branches. 
Achenia linear, somewhat angled, delicately striate. Pappus of few or many bristles, oftener smaller, 
fewer or simply reduced to scales in the ray than in the disk, or sometimes consisting entirely of small 
scales resembling a crown, or with these and the bristles intermixed.—Herbs, the leaves and involucral 
scales of which often abound in strong-scented glands. Flowers yellow [in P. imberbis purple ].—BENTH 
OOK.
