GREENMAN. — CENTRAL AMERICAN SPERMATOPHYTES. 47 



rous throughout : stem 8 to dm. high from a ligneous base, striate, 

 purplish: leaves bipinuately parted, 2 to 8 cm. long, 1.5 to 6.5 cm. 

 broad ; segments linear-lanceolate, acute, subequally serrate-dentate, often 

 setigerous, bearing a single row of glands on either iiaif 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 subcarapanulate, 10 to 12 mm. 

 high, G to 8 mm. in diameter, 8-dentate; teeth obtuse, slightly pubes- 

 cent : ray-flovvers 8 ; pappus of 1 to 5 narrow une(pial paleaceous awns 

 not exceeding the involucre; tube about 5 mm. in length, pubescent; 

 rays subobovate to oblong-cuneate, 1.2 to 1.5 cm. 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. — T. 

 peduncularis, Benth., PI. Hartw. 17 (1839), not Lag. — Mexico. State 

 of Jalisco: in pine woods, Bolafios. 1837, Hartweg^ no. 118 (hb. Gr.) ; 

 Sierra Madre, west of Bolanos, L6 September, 1897, Dr. J. N. Rose, 

 no. 3722 (hb. Gr., and hb. U. S. Nat. Mus,). Hartweg's number above 

 cited was referred doubtfully by Mr. Bentham to Tugetes peduncniaris, 

 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. peduncniaris, 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 cm. 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 cm. long upwardly thickened peduncles : involucre slightly fusi- 

 form, 1.0 to 1.7 cm. high : ray-flowers 5 ; tube 8 to 9 mm. long, incon- 

 spicuously pubcrulent ; 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
