Abstract
Attempts over the past 50 years to explain variation in the abundance, distribution and diversity of plant
secondary compounds gave rise to theories of plant defense. Remarkably, few phylogenetically robust tests of
these long-standing theories have been conducted. Using >50 species of milkweed (Asclepias spp.), we show
