Lepidospartum burgessii is a rare gypsophiliccshrub with limited distribution in New Mexico and Texas. Most of the known plants are restricted to two large populations, with a few small, isolated populations scattered in the surrounding area. The low recruitment observed in the two largest populations may be due to low seed set resulting from high inbreeding and/or self-incompatibility. We will use microsatellite loci to quantify diversity,
relatedness, inbreeding, population structure, and frequency of clonal reproduction.
