Missouri Bladderpod - physaria fioiformis

Missouri Botanical Garden is currently conducting a range-wide population genetics study of bladderpod (Physaria filiformis) using microsatellite markers.

The bladderpod (also known Missouri bladderpod and Limestoneglade Bladderpod) is a sun-loving annual that occupies limestone, dolomite, or shale glades, which are sparsely vegetated grasslands with shallow soils and exposed bedrock. Known from the limestone glades of the Springfield Plateau area of southwestern Missouri and from parts of Arkansas. The species is currently known from about 60 sites (in 1987, when the species was listed endangered, only 9 sites where known); further inventories may continue to uncover additional populations. Population sizes fluctuate greatly, but may reach half a million in the most favorable years. Populations may face significant threats from exotic plant species, especially Bromus tectorum, and from fire suppression and subsequent woody plant encroachment.

The Missouri Botanical Garden currently maintains 59 seed-bank accessions. In 2017-18, MBG is seed-banking populations using newly generated genetic data to guide sampling. We thank them from their important contributions to CPC!

The conservation experts at CPC participating institutions such as the Missouri Botanical Garden share their in-depth conservation expertise about rare plants through CPC’s National Collection Plant Profiles.
