BBOOM CORN. Brooms are made of the rays or pe-

BBOUGHTdNIA (Arthur Broughton, English bota- 

 nist). On'hidiiceo'. tribe Epidendre<p. Two or three W. 

 Indian Orchids much like Ltelia and Cattleya. Several 

 species which have been referred to this genus are now 

 distributed in Epidendrum, Maxillaria, Phajus, etc. 

 Plant producing pseudo-bulbs, and sendingup a bracted 

 scape bearing several or many showy fls. : calyx of 3 

 equal lanceolate sepals; two lateral petals broad -ovate 

 and somewhat crisped, the labellum round-cordate and 

 somewhat 2-lobed, crenate. with a spur at the base ad- 

 nate to the ovary. Require warmhouse treatment. Cul- 

 ture like that for Lfelia. Do not dry off enough to 

 shrink the bulbs. Prop, by division.

 ing of small tli-shy nutlets. Three species in E. Asia. 

 and there ofteu cultivated, the i>ark being used for 

 paper-making. Ornamental trees with broad, round 

 heads, but under culture often shrubby, of vigorous 

 growth when young, and effective by its large, often 

 deeply lobed foliage, not hardy north or only in very shel- 

 tered positions. They thrive best in rich, somewhat 

 moist soil and sheltered positions. Prop, by seeds, sown 

 after matiirity or in spring, by greenwood cuttings under 

 glass, or by cuttings of ripened wood, kept in colder 

 climates during the winter in the greenhouse ; also by 

 root-cuttings and layers. Budding in summer or graft- 

 ing in early spring in the greenhouse is sometimes 

 practised. Known as Paper Mulberries.

 than >2 in. in diam. China, Jap. — This species is more 

 tender than the former, which is also cultivated some- 

 times as B. K(pmpferi, while the true B. Kcempferi, 

 Sieb., with the lvs. resembling in shape those of B, 

 Kazinoki, but much smaller and pubescent, and with 

 very small fr. -heads, seems not to be cultivated.

BBOWALLIA (after John Browall, Bishop of Abo, 

 Sweden). SolantlceiP. A genus of about 10 South 

 American annuals, with abundant blue, violet or white 

 flowers. The seeds can be sown in the open border, but 

 for the sake of the earlier blooiu it is better to start 

 them indoors in early spring and transplant into the 

 open about May 15, where they will bloom profusely all 

 through our hot, dry summers, and until frost. They 

 can be grown in poorer soil than most half-hardy an- 

 nuals, and make excellent bedding plants. Thev are 

 also used for winter decoration, the seeds being sown in 

 midsummer, earlier or later according to the size of 

 the specimens desired. They should be placed near the 

 glass and frequently stopped, in order to produce com- 

 pact plants. Large specimens are excellent for cutting, 

 and small potted plants should be grown more com- 

 monly by fl.orists for home decoration at Christmas. It 

 is even possible to lift flowering plants from the open 

 before the first frost of autumn and pot them for con- 

 servatory decoration, though the flowers are likely to 

 become successively smaller. Blue flowers are rare in 

 winter, and Browallias are especially desirable for their 

 profuse bloom all through winter and early spring. 

 The flowers are. however, likely to fade, especially the 

 purple ones. In the names of the early species, Linnapus 

 commemorated the course of his acquaintancship with 

 Browall : elata, reflecting the exalted character of their 

 early intimacy ; f?emis«rt, its rupture ; a.nd alievafa, the 

 permanent estrangement of the two men. 



A. Corolla segments long, arumiuate : fls. large. 



specidsa, Hook. Lvs. sometimes opposite, sometimes 

 alternate : fls. thrice as large as in B. grandiflora, all 

 solitary, axillary: peduncle shorter than the lvs.: co- 

 rolla-tube thrice as long as the calyx, and abruptly 

 swelled at the top into a globular form : limb of 5 ovate.
