Trees or shrubs, with scaly bark, terete branchlets, terminal buds

formed in summer, and fibrous roots. Leaves usually clustered at the end

of the branches, revolute and entire on the margin, persistent or

deciduous. Flowers in terminal umbellate corymbs from buds with numerous

caducous scales; calyx 5-parted or toothed, persistent under the fruit,

corolla 5—10-lobed, deciduous; stamens 5 or 10, rarely more, more or

less unequal, ultimately spreading; filaments subulate-filiform, pilose

at the base; disk thick and fleshy, crenately lobed; ovary 5—10-celled;

style slender, crowned with a capitate stigma and persistent on the

fruit; ovules numerous in each cell, attached in many series to an axile

2-lipped placenta projected from the inner angle of the cell,

anatropous. Fruit a woody many-seeded capsule. Seed scobiform; seed-coat

loose, reticulate, produced at the ends beyond the nucleus into a short

often laciniate appendage; embryo minute, cylindric, axile in fleshy

albumen; cotyledons oblong, shorter than the radicle turned toward the

hilum.

Rhododendron with some four or five hundred species occurs in eastern

Thibet, on the Himalayas, in southwestern China, the Malay peninsula and

Archipelago, New Guinea, northern China and Corea, Japan, the mountains

of central Europe, on the Caucasus, and in eastern and western North

America, the largest number of species being found in southwestern China

and on the Himalayas. Of the twenty-three or twenty-four North American

species one only is arborescent.

Rhododendron possesses astringent narcotic properties. It produces hard

close-grained compact wood sometimes used in turnery and for fuel. Many

of the species are cultivated in gardens for the beauty of their large

and conspicuous flowers.

The generic name is from ῥόδον and δένδρον, the Rose-tree.

Bumelia, with about twenty-five species is confined to the New World,

where it is distributed from the southern United States through the West

Indies to Mexico, Central America, and Brazil. Of the twelve species in

the United States which have been distinguished five are small trees.

Bumelia produces hard heavy strong wood, that of the North American

species containing bands of numerous large open ducts defining the

layers of annual growth and connected by conspicuous branched groups of

similar ducts, presenting in cross-section a reticulate appearance.

short few-flowered bracted cymes; pistillate generally solitary; calyx

4-lobed, the lobes valvate in the bud, accrescent under the fruit;

corolla 4-lobed, the lobes sinistrorsely contorted in the bud, more or

less contracted in the throat, the lobes spreading or recurved; stamens

usually 16, inserted on the bottom of the corolla in two rows and in

pairs, those of the outer row rather longer than and opposite those of

the inner row; filaments free, slender; anthers oblong, apiculate, the

cells opening laterally by longitudinal slits; stamens rudimentary or 0

Diospyros, which is chiefly tropical, is widely distributed with more

than two hundred species in the two hemispheres, with a few species

extending beyond the tropics into eastern North America, eastern Asia,

southwestern Asia, and the Mediterranean region.

Diospyros produces hard close-grained valuable wood, with dark or black

heartwood and thick soft yellow sapwood. The ebony of commerce is partly

produced by different tropical species. The fruit is often edible, and

some of the species are important fruit-trees in China and Japan.

The generic name, from Διός and πυρός, is in allusion to the life-giving

properties of the fruit.

broad-ovate acute foliaceous ciliate calyx-lobes inflexed on the

margins; stamens with short slightly hairy filaments and

linear-lanceolate anthers opening throughout their length; pistillate

flower ¾′ long, with a greenish yellow or creamy white corolla nearly ½′

broad; stamens 8, inserted in one row below the middle of the corolla,

with short filaments and sagittate abortive or sometimes fertile

anthers; ovary conic, pilose toward the apex, ultimately 8-celled, and

gradually narrowed into the four slender styles hairy at the base. Fruit

on a short thick stem, ripening at the north late in autumn or earlier

southward, often persistent on the branches during the winter,

depressed-globose to ovoid or slightly obovoid, rounded or pointed at

apex, ¾′—2′ in diameter, yellow or pale orange color, often with a

bright cheek, and covered with a glaucous bloom, turning yellowish brown

when partly decayed by freezing, surrounded at base by the spreading

calyx 1′—1½′ in diameter, with broad ovate pointed lobes recurved on the

margins; flesh austere while green, yellowish brown, sweet and luscious

when fully ripened by the action of frost, or in some forms remaining

hard and green during the winter; seeds oblong, rounded on the dorsal

edge, nearly straight on the ventral edge, rounded at the ends, much

flattened, ½′ long and ⅓′ wide, with a thick hard pale brown rugose

testa, a narrow pale hilum and a slender raphe.

A tree, occasionally 50°—60° high, with a short trunk 16′—20′ in

diameter, spreading often pendulous branches forming a broad or narrow

round-topped head, and slender slightly zigzag glabrous or rarely

puberulous branchlets with a thick pith-cavity, light brown when they

first appear, becoming during their first winter light brown or ashy

gray and marked by occasional small orange-colored lenticels and by

elevated semiorbicular leaf-scars, with deep horizontal lunate

depressions; or in the primeval forest, under the most favorable

conditions, sometimes 100°—130° high, with a long slender trunk free of

branches for 70°—80° and rarely exceeding 2° in diameter; frequently not

more than 15° or 20° high and sometimes shrubby in habit. Winter-buds:

axillary, broad-ovoid, acute, ⅛′ long, with thick imbricated dark

red-brown or purple lustrous scales often persistent at the base of

young branchlets during the season. Bark of the trunk ¾′—1′ thick, dark

brown tinged with red, or dark gray, and deeply divided into thick

square plates broken into thin persistent scales, with heavy strong dark

brown sometimes nearly black heartwood often undeveloped until the tree

is over one hundred years old; used in turnery, for shoe-lasts,

plane-stocks, and preferred for shuttles to other American woods. The

fruit contains tannin, to which it owes its astringent qualities, and is

eaten in great quantities in the southern states. The inner bark is

astringent and bitter.

Distribution. Light sandy well drained soil, or in the Mississippi basin

sometimes on the deep rich bottom-lands of river valleys; Lighthouse

Point, New Haven, New Haven County, Connecticut, and Long Island, New

York, through southern Pennsylvania, southern Ohio, southern Indiana and

Illinois, to southeastern Iowa, eastern Kansas, central Oklahoma, and

southward to De Soto County, Florida, southern Alabama, Mississippi,

Louisiana, and Texas to the valley of the Colorado River (Burnet

County); very common in the south Atlantic and Gulf states, often

covering with shrubby growth by means of the stoloniferous roots

abandoned fields and springing up by the side of roads and fences;

ascending on the Appalachian Mountains to altitudes of 3500°; rare

toward the western limits of its range in Texas. In Missouri and

Arkansas passing into the var. _platycarpa_ Sarg. with larger

broad-ovate leaves rounded or cordate at base or rarely elliptic, more

or less densely pubescent on the lower surface, especially on the midrib

and petiole, often 2½′—4′ long and 2′—2½′ wide, and at the end of

vigorous shoots up to 6′ in length, and depressed-globose, yellow,

rarely nearly black (f. _atra_ Sarg.), fruit much depressed at top and

bottom, 1¾′—3′ wide and about 1′ high, with sweet succulent flesh,

ripening in September or early October, and seeds conspicuously rounded

on the dorsal edge, much compressed, dark chestnut-brown and lustrous,

only slightly rugose, ¾′ long and ½′ wide. A tree usually not more than

12°—25° high, with a trunk 16′—30′ in diameter and rather stouter

branchlets densely villose-pubescent sometimes for two or three years,

or becoming glabrate at the end of their first season. Hills near

Allenton, St. Louis County, and on the western slopes of the Ozark

Mountains and the adjacent prairies of southeastern Missouri and

prairies of northwestern Arkansas, eastern Kansas and Oklahoma. In Dade

County, Florida, _Diospyros virginiana_ is replaced by the var.

_Mosieri_ Sarg. with smaller staminate flowers, nearly globose fruit

with rather less compressed dark chestnut-brown lustrous only slightly

rugose seeds. A small tree with slightly fissured light gray bark.

Several named varieties of _Diospyros virginiana_ are distinguished and

cultivated by pomologists.

rufous tomentum, ashy gray, glabrous or puberulous during their first

winter, later becoming brown and marked by minute pale lenticels and by

small elevated semiorbicular leaf-scars displaying a lunate row of

fibro-vascular bundle-scars; often much smaller, and toward the northern

and western limits of its range a low many-stemmed shrub. Winter-buds

obtuse, barely more than 1/16′ long, with broad-ovate scales rounded on

the back and coated with rufous tomentum. Bark of the trunk smooth,

light gray slightly tinged with red, the outer layer falling away in

large irregularly shaped patches displaying the smooth gray inner bark.

Wood heavy, with black heartwood often streaked with yellow and clear

bright yellow sapwood; used in turnery and for the handles of tools. The

fruit, which is exceedingly austere until it is fully ripe, stains

black, and is sometimes used by Mexicans in the valley of the Rio Grande

to dye sheepskins.
