BOM AREA 



Ziiricli in ISOS. It has roroivrsl the name B.-C. Froe- 

 beli&na, Copn. This nat-iiral hybriil lias a slciulor erect 

 ptxluiu'lc i in. lonp, at the top bearing 2 nieiul)ranou.s 

 bracts half the length of the ovary: fl. 3'.i in, wide, the 

 sopals and jH>tals lanceolati^ligiilate, yellow-white, 

 lightly tinptni with rose, especially at the summit; dor- 

 ead sepal }X>intc<.l, curving outwarti at the top, the lateral 

 ones much incurved; petals obtuse, almost flat, curved 



589. Boltonia latisquama. ( X H) 



back at the tip; lip somewhat thick and fleshy, more 

 deUcate than in B. coekstis, the blade widely obovate 

 and rounded; crest orange-yellow, with a yellowish 

 border and an edge of brown-purple. 



BOLOCANTHUS, BOLUSANTHUS: Lophocarpus. 



BOLTONU (James Bolton, English botanist). Com- 

 ■p/jKilaf. False Chamomile. Four or .5 species of aster- 

 like glabrous often glaucous herbs of the United States 

 and ea-stem Asia, sometimes planted in borders and 

 wild gardens. 



They are tall and leafy plants, blooming profusely 

 in late summer and autumn, and excellent for the 

 hardy border. 'I'hey have alternate, entire and sessile or 

 clasping Ivs. and angled, often striate, sts. Differs from 

 Aster in having very few pappus bristles which in 

 Aster are numerous, and in other technical characters. 



Boltonias are of easiest culture. They take care of 

 theriLselves when once established. Propagation is 

 efTectwl by division. Should be better known to garden- 

 ers. They stand without staking. 



asteroides, I.'Her. {B. glaslifblin, L'Her.). Sts. 2-8 

 ft., simple below and branching at the top: Ivs. broadly 

 lanceolate or the upper narrower: heads short-pedun- 

 clcd, numerous, the rays varying from white to violet 

 and purjjle; involucral bracts lanceolate and acute, 

 greenish; scales of the pappus numerous and conspicu- 

 ous, the 2 aw^os sometimes missing. Pa. to 111. and S. 



P.M. 2381, 2,').'->4. Mn. 1:33. Gn. 74, p. 438. R.H 

 1903, p. 59.— Perennial. 



latisquama, Gray. Fig. 589. A handsomer plant, 

 with larger and more showy heads with blue-violet 

 rays: involucral bracts oblong or obovate and obtuse 

 (often bearing a minute point); pappus scales small, 

 the awns present and conspicuous. Kan. and Mo. to 

 Ark. G.P\ 5:271 (adapted in Fig. 589). C.L.A. 7:490. 

 Perennial. Yar. nana, Ilort. A dwarf form scarcely 

 2-3 ft. tall, with pinkish rayed fls. Branches freely 

 from the base. 



B. cantonUnsis, Franch. & Sav., is native to Japan, where the 

 young plants are used for greens. See Georgeson, A.G. 13, p. 8, fig. 

 4. It is annual. _ Has not yet appeared in the American trade. Gray 

 restricts Boltonia to the U. S., and regards his species as of another 

 genus. B. Ixvigata, Hort.=B. asteToidesil) 



BOLUSANTHUS: Lonchocarpus.

BOMAREA (named after the French botanist, J. C. 

 W. de Poniare). AmaryUidacese . Tender South Ameri- 

 can plants allied to Alstra-meria, and with similar fls. 

 but a twining habit. Lvs. parallel- veined, usually 

 borne on short, twisted petioles: fls. in pendulous 

 umbels, variously colored and spotted, borne in early 

 spring and summer; perianth funnel-shaped; tube 

 none. 



The most beautiful species now grown is probably 

 B. Carderi. It has large terminal cymes of rose-col- 

 ored flowers, about 2 inches long, with dark purple 

 spots and blotches. Another valuable form is B. Shut- 

 lleworlhii with pale yellow flowers, spotted with green. 



Bomareas delight in a rich, fibrous soil, and require 

 plenty of water during the growing season, which be- 

 gins early in the spring. A little well-decayed cow- 

 manure mixed with the soil improves the growth and 

 results in larger clusters of flowers, as does also manure 

 watering during the growing season. Late in fall the 

 stems are cut down to the ground and the roots are 

 kept in the soil in a dry state. While they often make 

 satisfactory pot-plants, they do best when planted out 

 in an open sunny position in a cool conservatory where 

 they have plenty of air in summer. In the south, 

 bomareas may be grown in the open air on trellises in 

 half-shady places. All are woodland plants and cannot 

 be successfully grown in the glaring heat of the sun. 



Propagation is by fresh seeds, which germinate 

 readily if sown in shallow pans in a warm propagating- 

 house; also, and more rapidly, by careful division of 

 the rhizome, to which some of the roots should be 

 attached. 



A. Perianth-segms. equal. 



B. Umbel simple; fls. medium-sized. 



oligantha, Baker. Lvs. 3-4 in. long, oblong, acute, 

 lax, thin, densely pubescent beneath: fls. 6-8 in an 

 umbel; bracts large, If.-like; segms. l-lJ4.in. long, 

 outer dull red, inner bright yellow with reddish brown 

 spots. Peruvian Andes.
