1. SYMPLOCOS L’Her.

Characters of the family.

Symplocos with nearly three hundred species inhabits chiefly the warmer

parts of America, Asia, and Australia, one species occurring in the

southern United States.

Symplocos contains a yellow coloring matter, and the bark and leaves of

some species have medical properties.

The generic name, from Σύµπλοκος, relates to the union of the filaments

of some of the species.

1. Symplocos tinctoria L’Her. Sweet Leaf. Horse Sugar.

scattered white hairs, reddish brown to ashy gray, tinged with red and

usually more or less pubescent or often covered with a glaucous bloom

during their first and second years, later growing darker, roughened by

occasional small elevated lenticels and marked by the low horizontal

obcordate leaf-scars displaying a central cluster of large

fibro-vascular bundle-scars; or more often a shrub. Winter-buds ovoid,

light, soft, close-grained, light red or brown, with thick lighter

colored often nearly white sapwood of 18—20 layers of annual growth. The

leaves are sweet to the taste and are devoured in the autumn by cattle

and horses, and, like the bark, yield a yellow dye occasionally used

domestically. The bitter aromatic roots have been used as a tonic.

Distribution. Moist rich soil, often in the shade of dense forests;

peninsula of Delaware to northern Florida and from the coast to

altitudes of nearly 4000° on the Blue Ridge in North and South Carolina,

and to eastern Texas and southern Arkansas; in the Gulf states usually

the short terete superior radicle turned toward the minute hilum.

The Olive family with twenty-five genera is widely distributed in

temperate and tropical regions chiefly in the northern hemisphere. Of

the five genera indigenous to the United States four are arborescent. To

this family belong _Olea europæa_ L., the Olive-tree of the

Mediterranean basin, now largely cultivated in California for its fruit,

and the Lilacs, Forsythias, Privets, and Jasmines, favorite garden

plants in all countries with temperate climates.

terminal buds much larger than the lateral buds. Leaves petiolate,

unequally pinnate or rarely reduced to a single leaflet, deciduous;

leaflets conduplicate in the bud, usually serrate, petiolulate or

sessile. Flowers diœcious or polygamous, produced in early spring on

slender elongated pedicels, without bractlets, in open or compact

slender-branched panicles, with obovate linear or lanceolate caducous

bracts, terminal on leafy shoots of the year, developed from the axils

of new leaves, or from separate buds in the axils of leaves of the

previous year, or at the base of young branchlets, and covered by 2

ovate scales; calyx campanulate, deciduous or persistent under the

united at base, or 0; stamens usually 2, rarely 3 or 4, inserted on the

base of the corolla, or hypogynous; filaments terete, short or rarely

elongated; anthers ovoid or linear-oblong, the cells opening by lateral

slits; ovary 2 or rarely 3-celled, contracted into a short or elongated

style terminating in a 2-lobed stigma; ovules suspended in pairs from

the inner angle of the cell; raphe dorsal. Fruit a 1 or rarely 2 or

3-seeded winged samara; body terete or slightly flattened contrary to

the septum, with a dry or woody pericarp produced into an elongated more

or less decurrent wing, usually 1-celled by abortion or sometimes 2 or

3-celled and winged. Seed solitary in each cell, oblong, compressed,

gradually narrowed and rounded at the ends, filling the cavity of the

fruit; seed-coat chestnut-brown.

Fraxinus with thirty to forty species is widely distributed in the

temperate regions of the northern hemisphere, and within the tropics

occurs on the islands of Cuba and Java. Of the eighteen North American

species here recognized all, with the exception of _Fraxinus dipetala_

Hook., of California, are large or small trees.

Fraxinus produces tough straight-grained valuable wood, and some of the

species are large and important timber-trees. The waxy exudations from

the trunk and leaves of _Fraxinus Ornus_ L., of southern Europe and Asia

Minor furnish the manna of commerce used in medicine as a gentle

laxative; and the Chinese white wax is obtained from the branches of

_Fraxinus chinensis_ Roxb.

_Fraxinus_ is the classical name of the Ash-tree.

rich bottom-lands of eastern Texas and here often 60°—70° high, with a

trunk 2°—3° in diameter; on the southern Appalachian Mountains ascending

to altitudes of 2000°—2500°. As it usually grows in the east with its

bright green glabrous leaves and glabrous branchlets the Green Ash

appears distinct from the Red Ash, but trees occur over the area which

it inhabits, but more often westward, with slightly pubescent leaves and

branchlets which may be referred as well to one tree as to the other and

make it impossible to distinguish satisfactorily as species the Green

Trees or shrubs, with oblong-obovate or ovate leaves involute in the

bud, persistent. Flowers on slender bracteolate pedicels, in terminal

corymbose many-flowered cymes, with linear-lanceolate caducous bracts

and bractlets; calyx campanulate, 5-toothed, the divisions closed and

valvate in the bud; corolla white, campanulate, the lobes broad-ovate,

spreading after anthesis; anthers ovoid, rugulose, apiculate; ovary

incompletely 4-celled by the development of the 2 parietal placentas,

narrowed into a terminal style 2-parted at apex, the divisions more or

less coalescent; stigmas capitate; ovules attached on the back near the

middle of the inner face of the revolute placentas, anatropous; raphe

ventral; micropyle superior. Fruit subglobose, flesh thin; stone

somewhat 4-lobed and separable into 4 thick-walled bony 1-seeded nutlets

rounded and furnished on the back with a thick spongy longitudinal

many-ridged appendage, flattened on their converging inner faces and

attached at apex to a filiform column. Seed terete, filling the seminal

cell, longitudinally incurved round a rather small cavity opposite an

elevated oblong scar on one of the inner faces of the nutlet and

connected with the hilum by a narrow passage; seed-coat membranaceous,

light brown; embryo axile in fleshy albumen; cotyledons plane; radicle

slender, elongated, turned toward the hilum.

Beureria with forty species is confined to tropical America, two species

reaching the shores of southern Florida; of these one is a tree and the

other _Beureria revoluta_ H. B. K. is an arborescent shrub.

The generic name is in honor of J. A. Beurer, an apothecary at

Nuremberg.

shrub; on the Bahama Islands and on many of the Antilles.

2. AVICENNIA L.

Trees, with coriaceous persistent leaves, stout pithy branches thickened

at the nodes and marked by interpetiolar lines, and long thick

horizontal roots producing numerous short vertical thick and fleshy

leafless stems rising above the surface of the soil. Flowers opposite,

cymose, in centripetal pedunculate spikes or heads, closely invested by

a bract and 2 bractlets, the peduncles solitary or in pairs in the axils

of upper leaves and ternate on the end of the branches, their bracts and

the apex in the bottom of the capsule to the withered columella by a

minute papillose point; plumule hairy.

Avicennia with three species is widely distributed on maritime shores of

the tropics of the two worlds, with one species reaching those of the

southern United States. Avicennia produces hard strong wood. The bark is

rich in tannic acid, and is used for tanning leather. The chief value of

these trees is in their ability to live on low tidal shores by the

structure of the embryo, which is growing and ready to take root as soon

as it falls into the soft mud, and in the long horizontal roots

furnished with short vertical fleshy leafless branches or aerating

roots, forming a close network which holds the soil together and

prevents it from being washed away by outflowing tides, and extends the

growth of the tree by numerous stems which soon form dense thickets.

The generic name is in honor of the illustrious physician of the Orient,

Avicenna of Bokhara (980—1036).
