ANSELLIA 



ANTHEMIS 



299 



ANSELLIA (in honor of John Ansell, African 

 explort'r). Urchidacea>. Epiphytic hothouse orchids 

 with tall, thickened leafy stems. 



Klowers in panicles, showy; sepals and petals similar, 

 spreading; lip erect, sessile at the end of the column- 

 foot; lateral lobes broad, parallel, erect; middle lobe 

 round-ovate, spreading ; pollinia 2. — A genus of 4 closely 

 related species, perhaps all forms of 1 species. 



africana, Lindl. Sts. up to 2 ft. tall, leafy above: Ivs. 

 4-8 in. long, about 5-nerved, elongated -lanceolate: 

 panicle many-fid.; fls. 2 in. across, with brown-purple 

 spots on a light yellow-green background; sepals nar- 

 row-oblong; petals about twice as broad as sepals; 

 lateral lobes of lip oblong, the middle lobe ovate. 

 Fernando Po. B.M. 4965. 



gigantea, Reichb. (Cymbidium Sdndersonii, Harv.). 

 Differs from the above in the smaller fls. with narrower 

 segms. which are spotted on the lower part only.

ANS6NIA: Amsonia. 



ANTENNARIA (pappus Ukened to antennse). Com- 

 pdbilx. Everlasting. Cat's-Ear. Ladies' Tobacco. 

 Pussy's Toes. P'ield herbs, sometimes offered by 

 dealers in native plants. 



Small, white-woolly perennial plants, with spatulate 

 or obovate root-lvs., and mostly leafless scapes, bearing 

 small gray or white heads which remain stiff and dry: 

 fls. dioecious, the staminate forms rare in cult., all 

 tubular, — None is showy. They are interesting for rock- 

 work and the edges of borders, and for this purpose 

 have been sparingly intro. in the last few years. They 

 are perfectly hardy, and thrive in poor soil. The fls. 

 are often cut before fully mature and dried (and often 

 dyed) as everlastings. About 20 species grow wild. 

 Prop, mostly by division of the mats; also by seeds. 

 Allied to Anaphalis and Gnaphalium, both of which 

 are leafy stemmed plants quite distinct from the pros- 

 trate, stemless antennarias, which send up only a 

 bracted scape, except in A.racemosa. See Everlastings. 



A. Pappus of sterile fls. not thickened at the tip, minutely 

 roughened. 

 dimSrpha, Torr. & Gray. Tufted, with spatulate Ivs. 

 and a sparsely Ivd. fl.-st. an inch or less high, from a 

 stout, much-branched rootstaUc. Neb. west to Calif. 



AA. Pappus of sterile fls. thickened at the top. 



B. Not spreading by stolons. 



Gejeri, Gray. Stout, thick-woolly, from a woody 



base: fls.-st. 3 in. or more high, very leafy to the top: 



pistillate heads narrow: involucre with rose-purple or 



ivory-white tips to the inner scales. Cahf. and Ore. 



BB. Spreading by stolons. 

 c. Heads solitary or in a cymose cluster. 



dioica, Linn. (.4. cdndida, Hort.). Basal Ivs. IH in. 

 or less long, 1-nerved or only indistinctly 3-nerved: St. 

 2-12 in.: involucral bracts all hght green or Ught brown, 

 with white or pinkish tips. Northern states and Eu., 

 and Asia. — The plant in the trade as A. tomenlosum 

 is probably a form of this species. Also in cult, under 

 the proper name, A. dioica. A. hyperborea, Hort., a 

 name common in the trade, is apparently a mere form 

 of this with pinkish fls. 



alpina, Gaertn. Plant 1-4 in.: involucral bracts in 

 fertile heads, dark browni.sh green, acute. Canada, 

 Rocky Mts., Sierra Nevadas. 



plantaginifdlia, Rich. Basal Ivs. 1 J^ in. or more long, 

 distinctly 3-nerv'ed: st. 6-18 in. high. — Stoloniferous, 

 making broad patches. Common in fields and old 

 pastures. Perhaps not in cult. 



cc. Heads loosely panicled. 

 racemdsa, Hook. Light-woolly, the flowering sts. 

 6-20 in. high, sparsely leafy, the heads mostly on slen- 



der peduncles: involucre brownish, white-tipped. Ore. 

 and Brit. Col. to the Rockies. 



A. margaritdcea^ADapha.[ia margaritacea.

ANTHEMIS (Greek name of the chamomile). Com- 

 positip. Chamomile. Pyrethrum-hke heavy-scented 

 plants, annual, biennial or perennial, members of a 



218. Anthemis tinctoria. ( X Ji) 



large, Old World temperate-region genus, used in bor- 

 ders and alpine gardens. 



Heads many-fld., the disk yellow, the rays white 

 and yellow and (in the common cult, species) pistillate, 

 the receptacle conical and chaffy, the achenes terete or 

 ribbed, and either naked or bearing a minute crown: 

 Ivs. pinnately dissected. 



Two or three of the species are weeds. Others are 

 excellent border plants. The true chamomile is a me- 

 dicinal plant. The hardy perennial species, which alone 

 are grown in this country, are easily handled in the 

 border, where they bloom from midsummer till frost. 

 They thrive in almost any soU, but need fuU exposure 

 to sun. 



Propagation is by seeds or division of the clumps, 

 usually the latter. 



a. Rays normally yellow. 



tinctflria, Linn. Golden Marguerite. Fig. 218. 

 Of bushy habit, 2-3 ft., with angular st. and pinnately 

 divided, and again pinnatifid or cut-toothed Ivs., and 

 large, daisy-Uke golden yellow fls. (1-2 in. across). 

 Gn. 42, p. 91; V. 18:133. A. Kelwayi, Hort. (or var. 

 Kelwayi, Hort.), has finer-cut foliage and deeper yellow 

 fls. There is also a pale-rayed variety and a white-fid. 

 form is sold under the name A. inontana. Gn. 52:484. 

 — An excellent hardy perennial border plant, and useful 

 at the same time for cut-fls.
