Abstract Detail
Systematics Morse, Keir [1]. Taxonomy and Conservation of the genus Malacothamnus (Malvaceae). Malacothamnus (Malvaceae) is a genus of “fire-following” shrubs found throughout much of California and northern Baja California with a disjunct location in central Arizona. The taxonomy of the genus is controversial due to overlapping morphological variation and limited analyses with between 11 and 28 taxa recognized by the three primary researchers. Resolving this taxonomy is of critical importance for conservation management as 16 Malacothamnus taxa currently have a California rare plant status. To address this, I am using a combination of morphometric analyses, restriction site associated DNA sequencing (RAD-Seq), and comparative phenology to assess the evolutionary relationships and morphological distinctions between hypothetical taxa in the genus. This is a work in progress. Here I present an introduction and preliminary data.
