ANSELLIA 



ANSfiLLIA (in honor of John Ansell, African 

 explorer). Orchiddcese. Epiphytic hothouse orchids 

 with tall, thickened leafy stems. 



Flowers 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-fld.; 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.

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

 Differs from the above in the smaller fls. with narrower 

 segms. which are spotted on the lower part only.

ANS&NIA: Amsonia. 



ANTENNARIA (pappus likened to antennae). Com- 

 pdsitse. EVERLASTING. CAT'S-EAR. LADIES' TOBACCO. 

 PUSSY'S TOES. Field 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 lip, minutely 

 roughened. 



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

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

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

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

 B. Not spreading by stolons. 



Geyeri, 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. Calif, and Ore. 



BB. Spreading by stolons. 

 ' c. Heads solitary or in a cymose cluster. 



dioica, Linn. (A. cdndida, Hort.). Basal Ivs. \ 1 A in. 

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

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

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

 and Asia. The plant in the trade as A. tomentosum 

 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 brownish green, acute. Canada, 

 Rocky Mts., Sierra Nevadas. 



plantaginifdlia, Rich. Basal Ivs. 1H in. or more long, 

 distinctly 3-nerved: st. 6-18 in. high. Stoloniferous. 

 making broad patches. Common in fields and old 

 pastures. Perhaps not in cult. 



cc. Heads loosely panided. 



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

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

ANTHEMIS (Greek name of the chamomile). Com- 

 pdsitx. CHAMOMILE. Pyrethrum-like heavy-scented 

 plants, annual, biennial or perennial, members of a 



218. Anthemis tinctoria. ( X h) 



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 soil, but need full exposure 

 to sun. 



Propagation is by seeds or division of the clumps, 

 usually the latter. 



A. Rays normally yellow. 



tinctoria, 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-like golden yellow fls. (1-2 in. across). 

 Gn. 42, p. 91; V. 18:33. 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-fld. 

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

 An excellent hardy perennial border plant, and useful 

 at the same time for cut-fls.
