 (Sorghum vulgare), the species which in other forms is 

 known as sorghum, kafir, and Guinea corn. For culti- 

 vation of broom-corn, see Cyclo. Amer. Agric., II, 216. 



BROSIMUM (Greek, edible). Horaces:. A genus of 

 8 species of large trees of Trop. Amer., yielding edible 

 f r. : fls. monoecious, or rarely dioecious, inside or on the 

 outside of a fig-like receptacle. B. Alicdslrum, Swartz, 

 is the bread-nut of Jamaica, but it is not grown within 

 the U. S., except in most of the botanic gardens. It 

 bears round yellow fr., about an inch in diam., con- 

 taining a single large seed, which is edible after 

 roasting. The tree has shining lance^elliptic entire Ivs. 

 Prop, by cuttings of young wood in a bell-jar with 

 bottom heat. 



BRpUGHTONIA (named in honor of an English 

 botanist, Arthur Broughton). Orchiddcess. Epiphytic

petals similar, somewhat spreading, the latter a little 

 the broader; lip sessile on the base of the column or 

 sometimes a little adnate, lateral lobes inclosing the 

 column, middle lobe spreading; ovary extended into a 

 long cavity; pollina 4, waxy. A West Indian genus of 

 2 or 3 species. Sometimes united with Epidendrum. 



sanguinea, R. Br. Pseudobulbs up to 2 in. long, 

 2-lvd.: Ivs. 2-4 in. long, leathery, linear-oblong: racemes 

 of 510 fls. about 1 % in. across and of a crimson-purple; 

 sepals lanceolate, acute; petals oval-oblong; lip nearly 

 orbicular, denticulate on the margin. Jamaica. B.M.

BROUSSONfeTIA (after T. N. V. Broussonet, a 

 French naturalist). Moracex. Ornamental trees or 

 shrubs, grown chiefly for their large handsome foliage. 



Leaves alternate, petioled, serrate, undivided or 

 lobed: fls. dioecious, apetalous, the staminate in cylin- 

 drical, nodding catkins, with 4-parted calyx and 4 sta- 

 mens, the pistillate in globular heads with a tubular 

 perianth including the stalked ovary; stigma filiform: 

 collective fr., a dense globose head consisting of the 

 persistent perianths and bracts with numerous small 

 1-seeded drupelets protruding at maturity and orange 

 red. Three species in E. Asia, and there often cult., 

 the bark being used for paper-making. 



These are deciduous trees with wide-spreading 

 branches, under culture often shrubby, with rather 

 inconspicuous greenish white flowers. B. papyrifera, 

 the hardier of the two species in cultivation, is fairly 

 hardy as far as north New York. It is usually a small 

 tree with a rather low wide-spreading head and may be 

 used in cities in situations in which small shade trees 

 are wanted, as it stands heat and dust well. It is not 

 particular as to the soil. 



Propagation is by seeds, sown after maturity or in 

 spring, by greenwood cuttings under glass, or by cut- 

 tings of ripened wood, kept in colder climates during 

 the winter in the greenhouse; also by root-cuttings with 

 slight bottom heat and layers. The varieties are also 

 sometimes budded in summer or grafted in early spring 

 on the roots of the type in the greenhouse. Known as 

 paper mulberries. 



papyrifera, Vent. (Mbrus papyrifera, Linn.). Tree, 

 30-50 ft., with thick, pubescent branches: Ivs. long- 

 petioled, usually cordate-ovate, acuminate, coarsely 

 dentate, often deeply lobed, especially on younger 

 plants, rough above, pubescent beneath, 3-8 in. long: 

 fr. -heads %in. across, red. May.
