7. =Fràxinus excélsior=, L. (EUROPEAN ASH.) Leaflets 11 to 13 (in some cultivated varieties reduced to 1 to 5), almost sessile, lanceolate-oblong, acuminate, serrate, wedge-shaped at base. Flowers naked, somewhat dioecious, and so the fruit does not form on all the trees. Keys linear-oblong, obtuse, obliquely notched at apex. This species in its very numerous varieties is common in cultivation. One of the most interesting is the Weeping Ash (var. _pendula_). The most remarkable is the one with simple, from pinnatifid to entire leaves (var. _monophylla_). [Illustration: F. òrnus.] 8. =Fráxinus òrnus.= (FLOWERING ASH.) Leaflets 7 to 9, lanceolate or elliptical, attenuated, serrated, entire at the stalked bases, villous or downy beneath. Flowers fringe-like, white, in large terminal drooping clusters, of 4 or 2 petals. May to June. Fruit small, lance-linear, obtuse, attenuate at each end. A small tree, 15 to 30 ft. high, planted in parks. Not hardy north of New York City without some protection. GENUS =61. OSMÁNTHUS.= Shrub or small tree with opposite, thick, evergreen, nearly entire leaves. Flowers small, white, in panicles or corymbs in late spring. Fruit a spherical drupe, ½ in. long, with a 2-seeded stone; hanging on during the winter. [Illustration: O. Americàna.] =Osmánthus Americàna, L.= (DEVIL-WOOD.) Leaves thick, evergreen, oblong-lanceolate, entire, acute, narrowed to a petiole, 4 to 5 in. long. Flowers dioecious, very small. May. Fruit globular, about ½ in. in diameter, violet-purplish; ripe in autumn, and remaining on the tree through the winter. A small tree, 15 to 20 ft. high, from southern Virginia southward, in moist woods. GENUS =62. SYRÍNGA.= Leaves simple, entire, opposite; flowers ornamental, in large, dense clusters. The Lilacs are all beautiful, but form mere shrubs, except the following: [Illustration: S. Japónica.] =Syrínga Japónica.= (JAPAN LILAC. GIANT TREE LILAC.) Leaves deciduous, opposite, oval to cordate, thick, dark green, glossy; flowers white, 4-parted, odorless, in very large, dense, erect, terminal clusters, blooming in summer; fruit dry 2-celled pods with 2 to 4 seeds. A magnificent small tree, 20 to 30 ft. high; from Japan; probably hardy throughout. GENUS =63. CHIONÁNTHUS.= Low trees or shrubs with simple, deciduous, opposite, entire, thick, smooth, petioled leaves. Flowers 4-parted, with long, slender, delicate white lobes, drooping in clusters from the lower side of the branches and forming a fringe; in early summer. Fruit a purple drupe. [Illustration: C.
