description
Magonia pubescens grows as a deciduous, quite fast-growing tree, with a dense crown to about 9-10 meters high. The trunk diameter reaches about 30 centimeters. The grayish to brownish bark has small scales.
The alternate and stalked leaves are pinnate in pairs with about 6–12 leaflets . The entire, ovate to obovate, oblong or ovate to ovate to ovate and rounded or rounded to indented, edged leaflets are (almost) sessile. They are up to 11.5 inches long and up to 6 inches wide, they are lighter underneath and slightly hairy. The stipules are missing.
Magonia pubescens is monoecious . Fine-haired and loose, paniculate , terminal or axillary inflorescences are formed. The stalked and five-fold, functionally unisexual, slightly fragrant flowers have a double flower envelope . The fine-haired, five-part and small calyx is yellow-greenish. The elongated, narrow, about 1–1.3 centimeters long and spreading petals are fine-haired and yellow-green on the outside and purple-red on the inside. There are about 8 stamens . The three-chambered, short hairy ovary is on top. The male flowers have a pistillode and the female staminodes. There is a cup-shaped, double-layered disc on one side and here elongated concave upwards .
Spherical, about 7.5–11.5 centimeters in size, brownish and slightly scabbed, somewhat rough, glabrous, woody, loculicidal, three-part, multi-seeded capsule fruits are formed. The flat, orange-brown, elliptical to kidney-shaped, myxosperm seeds, with a soft, papery seed coat are winged all around and with wings about 5.5–8.5 centimeters long.
use
The leaves can be used as fish poison . The bark is used medicinally. Soap can be made from the seed oil.
The fairly durable, moderately hard and heavy wood can be used for various applications.
