§ 4. TiiYiioPHtLLA. Gray. Pale* of the pappus o to 12, truncate and muti- 

 cous (yet in one .species occasionally some are sliort-awned 1 ), somewhat coriaceous, 

 distinct or eupulately connate. — ■ Proc. Am. Acail. xix. 4.'. Thymophylla, Lag.

* Fruticulose plants, with habit and character of the acerose-leaved genuine species of Hijmev,a-

H. si;tif6lium, Gra_v, 1. c. {Thi/mophylla selifolia, Lag. 1. c, on which the long imperfectly- 

 known genus was founded), may possibly reach our limits. It has a canescent involucre, no 

 rays, and normally ^ pajipns of 5 or 6 distinct quadrate paleoe. But in some specimens of 

 I'arry and Palmer's no. .316 occurs an inner alternating .series of longer and narrower aristate 

 paleae, — completely invalidating Laga.^ca's genu,--. 



H. Greggii, Oe.it. a span or two high in dense tufts : branches thickly leafy up to the 

 filiform glabrate peduncles : leaves white-tomentose, short, Heathdike ; lower 3-7-parted, 

 upper entire, setaceous : involucre campanulate, glabrous, naked at base : rays 10 to 12, 

 short, but distinctly exserted, sunietiuies wanting : paleae of the pappus united into an entire 

 truncate cup. — Proc. Am. Acad. xix. 42. Tlii/mophi/lla Grerjyii. Gray, PI. Fendl. 92 (speci-

* * Annual, wholly glabrous, wholly resembling H. polychaetum and its near allies, except the 

 pappus. — LoweU'uij Gray. 



H. auretun, Gkat. a span or two high, erect or diffuse, much branched, bearing numer- 

 ous short-peduncled heads : leaves mostly alternate, pinnately parted into 7 to 9 linear-fili- 

 form pointless divisions : involucre broadly campanulate, 3 lines high : rays about 12, oblong, 

 3 lines long: pappus of 6 or 8 quadrate or oblong and erose-truncate palea;, in length httle 

 exceeding the breadth of the akene, — Proc. Am. Acad. xix. -12. LoaiUia aurea, Gray, PI.

168. TAGETES, Tourn. (A name of the early botanists for the 

 ^'■French" or '■African Marigold" of the gardens, T. patula, and its larger 

 form, T. erecta, L. Fuschius says it was applied by Apideius to the Tansy : 

 some derive the word from Tages, an Etruscan deity.) — Mexican and S. Amer- 

 ican herl)s, mostly annuah, stroug-sreuted, branching; with opposite and some- 

 times alternate leaves, in one species nearly entire, in most pinnately divided, 

 having- copious oil-glands, bearing large and showy or small and comparatively 

 inconspicuous heads of mostly yellow or orange flowers, in cultivation some flame- 

 colored or reddish. — Inst. 4S8, t. 278; L. Gen.; DC. Prodr. v. 642; Gray, 

 Proc. Am. Acad. xix. 42. 



T. LUCID.4, Car., the species with simple and narrow ses.sile leaves, and cymose heads with 



2 or 3 rather showv rays, may yet be found within our Jlexican border. One of our two in- 

 digenous s]iecies has handsome exserted rays, the other has inconspicuous rays and the most 

 slender heads in the genus. 



T. Lemmoni, G-rxy. Xearly glabrous, 2 or 3 feet high from a perennial root, lignescent at 

 base, rather slender, fastigiately branched, bearing numerous cymosely disposed heads on 

 slender short peduncles : leas es'all opposite, 3-7-foliolate ; leaflets lanceolatedinear or some- 

 times lanceolate-oljluijg, with attenuate base, serrulate, not setiferous (an inch or two long), 

 sometimes a minute lower pair: inrolucre turbiuate-campanulate, 4 lines high: rays 6 to 8, 

 nearlv halt-inch long, obovate-oblong : lobes of the disk-coroUa nearly beardless: pappus
