The leaves of bumald bladdernut are composed of three elliptic to lance-shaped leaflets, each up to 2 inches (5 cm) long. The tips taper to a point. The upper side is a darker green compared to the lighter, hairy underside, particularly along the veins. This color contrast and the persistent hairs on the veins are key identification features.

Bumald bladdernut flowers consist of mildly fragrant, reddish panicles of small, dull to creamy white blooms appearing from May to June. Each tiny flower, reaching around 0.2 inches (5 mm) in diameter, features a delicate and modest arrangement of petals. The clusters, or panicles, span approximately 2-3 inches (5-8 cm) in length, with a subtle scent that adds a gentle charm to their presence. This distinctively understated yet elegant flower display enhances the plant's visual appeal during its blooming period.

The stem of bumald bladdernut features a multistemmed suckering habit, often leading to the formation of a dense, thicket-like appearance. The stems are moderately thick, typically measuring around 0.5 inches (1.27 cm) in diameter. They exhibit a smooth texture with a greenish-brown hue, transitioning to a more pronounced brown as they mature. Branching is profuse, contributing to its bushy structure. Distinctive for its ability to produce new shoots from the base, promoting extensive lateral growth.

The fruit of bumald bladdernut manifests as distinctive, bladder-like seed capsules. Initially emerging as a vibrant green, these capsules gradually dry and transition to a brown hue, reflecting the fruit's maturation. Typically, they retain their inflated appearance, providing a key identification trait. Each capsule securely encases seeds that possess a subtle yellow tint, contributing to the fruit's unique character. While fresh, the surface of the fruit maintains a certain firmness to touch, softening and becoming more brittle with age. Notably, the transition in color and texture of the fruit provides visual cues for the different stages of its lifecycle.
