Abstract Detail
Systematics Section / ASPT Farmer, Susan B. [1], Schilling, Edward [1]. Status of the Trillium pusillum species complex. TRILLIUM pusillum is a widespread spring ephemeral of the southeastern United States. The composition of this group in recent taxonomic treatments has ranged from a single species that may or may not have associated subspecific taxa to several species. Each of these taxonomic entities is geographically and ecologically distinct. Analysis of chloroplast and nuclear DNA sequence data has clarified the taxonomic boundaries within this group. This sequence data coupled with a morphological analysis has led to a better understanding of these taxa.
