General Information
Shorts bladderpod is distinguished in the field from other yellow-flowering mustards with a shared distribution based on dense pubescence (fine hairs) that gives the leaves a gray-green appearance, the small pubescent siliques (pods) born on straight pedicels (stems that attach single flowers to the larger flowering structure), and stems that are typically (though not always) branching to give the plant a low, sprawling, bushy appearance disinguish (Rollins and Shaw 1973, pp. 166-169, Shea 1993, p. 5). The following technical description of Shorts bladderpod is based on Flora of North America (OKane 2010, p. 639), Gleason and Cronquist (1991, p. 187), and Krosnick et al. (in prep). Shorts bladderpod is an upright biennial or perennial (lives for 2 years or longer) with several stems, some branched at the base, reaching heights up to 50 centimeters (cm) (20 inches (in.)), and which are leafy to the base of the inflorescence (a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches). The basal leaves, borne on short petioles (stalks) are 2.5 to 5 cm (1 to 2 in.) in length and 0.5 to 1.5 cm (0.2 to 0.6 in.) wide, obovate (egg-shaped and flat, with the narrow end attached to the stalk) or oblanceolate (with the widest portion of the leaf blade beyond the middle) in shape, with a smooth or slightly wavy margin, and gray-green in color due to a layer of dense hairs. Leaves are gradually reduced in size and petiole length higher up the stem. Numerous flowers are borne on a heterothetic compound raceme, with a rachis consisting of both primary (vertical) and secondary (lateral) axes, each of which produces an indeterminate raceme (elongate, spike-shaped inflorescence to which individual flowers are attached by slender pedicels, or stalks, which in Shorts bladderpod are longer than the flowers). The yellow flowers are composed of four spoon-shaped petals, 0.4 to 0.7 cm (0.16 to 0.28 in.) long, with a nectary at the base of each petal. The fruit is globose in shape and lightly beset with stellate (star-shaped) hairs, but becoming smooth with time, and typically contains one to four seeds.The species historical range included Indiana, Kentucky, Tennessee.

Habitat Requirements
Shorts bladderpod typically grows on steep, rocky, wooded slopes and talus areas. It also occurs along tops, bases, and ledges of bluffs and infrequently on sites with little topographic relief. The species usually is found in these habitats on south- to west-facing slopes near rivers or streams, and most populations are closely associated with calcareous outcrops. The most vigorous and stable occurrences are found in sites with a relatively open overstory canopy.
