GREENMAN, — CENTRAL AMERICAN SPERMATOPHYTES. 47 
rous throughout: stem 8 to 9 dm. high from a ligneous base, striate, 
purplish: leaves bipinnately parted, 2 to 8 cm. long, 1.5 to 6.5 em. 
broad ; segments linear-lanceolate, acute, subequally serrate-dentate, often 
setigerous, bearing a single row of glands on either half of the blade at 
the base of the teeth: heads about 1.5 cm. high, including the rays 2.5 
to 3.5 cm. in diameter, terminating the stem and branches on long slender 
0.5 to 1 dm. long peduncles: involucre subcampanulate, 10 to 12 mm. 
high, 6 to 8 mm. in diameter, 8-dentate; teeth obtuse, slightly pubes- 
cent: ray-flowers 8; pappus of 1 to 5 narrow unequal paleaceous awns 
not exceeding the involucre; tube about 5 mm. in length, pubescent ; 
rays subobovate to oblong-cuneate, 1.2 to 1.5 em. long, 7 to 11 mm. 
broad, emarginate, deep orange-yellow: disk-flowers 35 to 45; pappus 
much-reduced or quite obsolete ; corollas deeply 5-toothed with the tube 
pubescent below, glabrous above, and the teeth pubescent on the in- 
side especially along the margins: achenes 6 mm. long, glabrous. — 7. 
peduncularis, Benth., Pl. Hartw. 17 (1839), not Lag. — Mexico. State 
of Jalisco: in pine woods, Bolafios, 1837, Hartweg, no. 118 (hb. Gr.) ; 
Sierra Madre, west of Bolafios, 16 September, 1897, Dr. J. WV. Rose, . 
no. 8722 (hb. Gr., and hb. U. S. Nat. Mus.). Hartweg’s number above 
cited was referred doubtfully by Mr. Bentham to Tagetes peduncularis, 
Lag.; but the excellent specimens secured by Dr. Rose, which are iden- 
tical with the Hartweg plant in the Gray Herbarium, show very clearly 
that the two species have but a superficial resemblance. The single row 
of submarginal leaf-glands, the 8-dentate involucre, the numerous flowers, 
and finally the usually epappiferous character of the disk-flowers render 
T. Hartwegii an easily recognizable species, readily distinguished from 
T. peduncularis, Lag., with which it has been confused. 
: Tagetes jaliscensis, n. sp. An erect glabrous annual 3 to 4.5 dm. 
in height : stem simple and terete below, branched and striate or angu- 
late-striate above, green or somewhat purplish: leaves opposite below, 
alternate above, 3 to 10 em. long, 1.5 to 4 cm. broad, deeply pinnatisect 
with 9 to 15 narrowly-lanceolate acute subincised-dentate segments and 
with 4 to 8 smaller setiferous segments at the base; the punctate glands 
more or less scattered in the leaf-lamina: heads corymbosely disposed on 
2 to 4 em. long upwardly thickened peduncles: involucre slightly fusi- 
form, 1.5 to 1.7 em. high: ray-flowers 5; tube 8 to 9 mm. long, incon- 
spicuonsly puberulent; rays cuneate-oblong, 5 to 6 mm. long, and nearly 
or quite as broad, emarginate, deep orange: disk-flowers about 12; cor- 
ollas tubular, rather deeply 5-lobed; lobes pubescent and, as well as the 
upper portion of the tube, colored like the rays: pappus of both ray- and
