rees, with leaves furnishing a yellow dye.

alternate, thick, 3 to 5 in. long, elongate-oblong, acuminate, nearly
entire, almost persistent, pale beneath, with minute pubescence,
sweet-tasting. Flowers 6 to 14, in close-bracted, axillary clusters,
5-parted, sweet-scented, yellow; in early spring. Fruit a dry drupe,
ovoid, 1/2 in. long. A shrub or small tree, 10 to 20 ft. high. Delaware

ORDER =XXIX. OLEACEAE.= (OLIVE FAMILY.)

An order of trees and shrubs, mainly of temperate regions.

GENUS =60. FRAXINUS.=

Trees with petioled, opposite, odd-pinnate leaves (one cultivated
variety has simple leaves). Flowers often inconspicuous, in large
panicles before the leaves in spring. Fruit single-winged at one end
(samara or key-fruit), in large clusters; ripe in autumn. Some trees,
owing to the flowers being staminate, produce no fruit. Wood
light-colored, tough, very distinctly marked by the annual layers. The
leaves appear late in the spring, and fall early in the autumn.

[Illustration: F. Americana.]

1. =Fraxinus Americana=, L. (WHITE ASH.) Leaflets 7 to 9 (usually 7),
stalked, ovate or lance-oblong, pointed, shining above, pale and either
smooth or pubescent beneath, somewhat toothed or entire. Flowers almost
always dioecious (May), thus the fruit is found on but a portion of
the trees. The fruit (August to September) terete and marginless below,
