description
Vegetative characteristics
Acacia celastrifolia grows as a shrub that can reach heights of 1 to 3 meters. All parts of the plant are bare. The bark is smooth in young trees and becomes deeply fissured with age. The usually frosted bark of the branches is finely ribbed and, like the bark, bare.
The wavy, curved, leathery and green to gray-green to almost blue-green phyllodes are 3 to 7 centimeters long and 1.5 to 3.5 centimeters wide, obovate, lanceolate to elliptical in shape. The hardened tip of the leaf is blunt, tapering sharp to spiky. The midrib and the leaf veins on the leaf margin are raised and yellow in color. The few side nerves are inconspicuous. There is a noticeable leaf gland about 0.5 to 2 centimeters above the pulvinus .
Generative characteristics
The somewhat stocky inflorescence shafts are 3 to 10 millimeters long. The 3 to 12 centimeters long, racemose total inflorescences contain ten to twenty spherical, capillary partial inflorescences, each containing two to three flowers.
The light golden yellow to sometimes sulfur yellow, hermaphrodite flowers are radial symmetry and four-fold with a double flower envelope . The four sepals are fused to form a calyx that ends with trimmed to lobes. There are three to five bald and sessile in each flower ovary .
The leathery to slightly woody legumes are more or less straight to slightly curved and have thickened and wavy edges. They are linearly shaped with a length of up to 12 centimeters and a thickness of 0.3 to 0.4 centimeters. The slightly shiny, mostly brown seeds are oblong with a length of 4 to 5 millimeters. The aril is terminal.
