Kodachrome bladderpod is a small but charming perennial herbaceous plant that forms as a dense rounded clump 4 cm tall. Its leaves are between 1 and 10 mm in length, and only about 1 mm wide. They are covered in fine hairs arranged in a star-shaped pattern. The tiny yellow flowers of Kodachrome bladderpod have petals 5 to 7 mm long that are spatula-shaped. The fruit is an ovoid (resembles an egg) and densely covers the plant. The length of the fruit is about 3 mm, with 2 to 4 seeds in each. Plants can usually be seen flowering beginning in late April and continuing through May, with seed dispersal occurring in June. Although the species was threatened by energy and mineral extraction activities, with the creation of Grand Staircase-Escalante National Monument (GSENM) in 1996, those activities are no longer considered a threat (USFWS 2009, Natureserve 2013). The largest threat to the species currently is illegal OHV use because the plants occupy barren rolling hills, which are easily accessed from the main road and are sought out by OHV recreationists (USFWS 2009).
