Introduction：
Juglans microcarpa is a large shrub or a small tree that grows up to 15 m tall with low hanging branching. Leaves 12-29 cm; leaflets 17-25, lanceolate or narrowly lanceolate, weakly to strongly falcate, 5.2-6.3(-9.6) × 0.8-1.1(-2.2) cm, margins entire or toothed, apex long-acuminate; surfaces abaxially with capitate-glandular hairs (sometimes becoming sparse late in season except along veins). It has a gray to dark brown trunk and produces a greenish fruit with capitate-glandular hairs that turns black at the end of fall. Nuts globose to depressed-globose, 1.1-1.7 cm, grooved, surface between grooves smooth. J. microcarpa grows from southwestern Kansas all the south into Northeastern Mexico and grown in sandy and loamy soils.
