ARTABOTRYS 



ARTEMISIA 



399 



wedge-shaped, with a very broad truncate or flattened 

 connective above the two pollen-sacs; ovaries few, about 

 3-5, broadly ovoid, subcompressed, terminating in a 

 email stigma and containing 2 basal ovules; fruiting 

 carpels 2 or 3, oblong, obtuse, slightly contracted at the 

 base, sessile; seed usually solitary. All Malayan prov- 

 inces at low elevations, common; distribution from 

 Sylhet to Burma; also occurring 

 in the Philippines. The natives 

 use this plant to form hedges and 

 fences, interweaving the long sar- 

 mentose branches, which form an 

 effective barrier against, cattle and 

 buffalo. Often planted near 

 houses on account of the 

 exquisite fragrance of its fls. 

 Suitable for forming in- 

 closures in Fla., Porto Rico, 

 Hawaii, and S. Calif.

ARTEMISIA (Artemisia, 

 wife of Mausolus). Com- 

 posite. WORMWOOD. A 

 large genus of aromatic 

 and bitter herbs and small 

 shrubs, mostly in the 

 northern hemisphere, 

 and most abundant 

 in arid regions. 



Leaves alternate, 

 often dissected : heads 

 small and mostly in- 

 conspicuous, numer- 

 ous, and generally 

 nodding, with yellow 

 or whitish florets, 

 wholly discoid, the 

 involucre im- 

 bricated in 

 several rows. 



In the West, 

 y*-' many of the 

 species, parti- 

 cularly A. tri- 

 denlata, are 

 known as sage brush. Grown for their medicinal prop- 

 erties or for foliage effects. The drug product of the 

 artemisias is large. A. Absinthium is the chief source 

 of absinthe; A. Barrelieri, Bess., of Spain, is said to be 

 used in the preparation of Algerian absinthe; A. Cina, 

 Berger, of the Orient, is the source of santonica. The 

 garden kinds are perennials and thrive in the most 

 ordinary conditions, even in poor and dry soil. Propa- 

 gation IB mostly by division. 



385. Artemisia Stellfriana, one of the 

 Dusty Millers. 



A. Heads with two kinds of florets (heterogamous). 



B. Disk-fls. with both stamens and pistils, but the ovary 



abortive (not producing seed); style usually entire. 



1. Dracunculus, Linn. TARRAGON. ESTRAGON. Herb; 

 green and glabrous, with erect, branched sts. 2 ft. 

 high: radical Ivs. 3-parted at the top; st.-lvs. linear 

 or lanceolate^ entire or small-toothed: panicle spread- 

 ing, with whitish green, nearly globular fl.-heads. Eu. 

 R.H. 1896, p. 285. Tarragon Ivs. are used for seasoning, 

 but the plant is little grown in this country. The Ivs. 

 may be dried in the fall, or roots may be forced in a 

 coolhouse in the winter. Prop, by division; rarely pro- 

 duces seed. See Tarragon. 



2. canadensis, Michx. Herb, 2 ft. or less high, glabrous 

 or very nearly so: Ivs. usually 2-pinnate, with filiform, 

 plane lobes: fls. in a long, narrow panicle, with numer- 

 ous small greenish heads. Wild on banks and plains in 

 the northern part of the country. 



3. filifolia, Torr. Shrubby, canescent, 3 ft. or less 

 high, very leafy, the branches rigid: lys. 3-parted into 

 linear filiform segms., scarcely rein, wide: panicle long 

 and leafy. Plains, W. Plant has a purplish, mist-like 

 aspect when in fr. 



BB. Disk-fls. perfect and fertile; style 8-deft. 



c. Receptacle hairy. 

 D. Racemes not 1 -sided. 



4. frigida, Willd. Herb, 8-12 in., with a woody base, 

 silvery canescent: Ivs. much cut into linear lobes: 

 heads small and globular, with pale involucre, in nu- 

 merous racemes. Plains and mts. W. Intro. 1883. 

 Good for borders. Known in Colo, as "mountain 

 fringe," and used medicinally. 



5. sericea, Web. Sub-shrub or more usually a creep- 

 ing woody perennial with finely divided silky foliage: 

 If .-segms. distinctly stalked: fl.-heads in solitary or 

 paniculately branching racemes, yellowish white. Sum- 

 mer. Siberia. 



6. argentea, L'Her. Shrubby, erect, 1-2 ft.: Ivs. 

 white-silky, 2-pinnate, the lobes linear or lanceolate: 

 heads globular, tomentose, nodding, in racemose pani- 

 cles. Madeira. Useful for rockwork. 



7. Absinthium, Linn. WORMWOOD. ABSINTHIUM. 

 Almost shrubby, 2-4 ft. high, spreading and branchy, 

 white-silky: Ivs. 2-3-parted into oblong, obtuse lobes: 

 heads small and numerous, in leafy panicles. Worm- 

 wood is native to Eu., but it occasionally escapes from 

 gardens. It is a common garden herb, being used in 

 domestic medicine, especially as a vermifuge. Worm- 

 wood tea is an odorous memory with every person 

 who was reared in the country. See Absinthe and 

 Wormwood. 



DD. Racemes 1-sided. 



8. arborescens, Linn. Shrubby, 1-2 ft., the sts. erect 

 and angled: foliage finely dissected, silvery white, the 

 upper Ivs. almost sessile, the lower petiolate: fls. in 

 somewhat 1-sided racemes, bright yellow. Medit. re- 

 gion. Hardy only as far north 



as Washington, D. C. 



cc. Receptacle not hairy. 



D. Lvs. white or silvery 

 throughout. 



9. Stelleriana, Bess. (A. en- 

 dovicidna, Hort.). OLD WOMAN. 

 DUSTY MILLER. BEACH 

 WORMWOOD. Fig. 385. Herb, 

 2 ft., from a woody creeping 

 base, densely white tomentose: 

 Ivs. pinnatifid, with obtuse 

 lobes: heads large and many- 

 fld., in a racemose-glomerate 

 infl. N. E. Asia and on the 

 Atlantic coast from Mass, to 

 Del. Attractive from its 

 whiteness. Useful for borders. 



10. Purshiana, Bess. (A. 

 gnaphalddes, Nutt. not Hort.). 

 Sta. and Ivs. white-woolly on 

 both sides, differing from A. 

 ludoviciana in which the Ivs. 

 are usually glabrate above 

 when old: Ivs. acute or acumi- 

 nate, overtopped by the spi- 



cate-paniculate infl. of white 386. Artemisia pontica. 

 fls. Missouri R. to the Pacific. (XK)
