This study provides molecular classifications by nuclear magnetic resonance spectroscopy for exudates from the monocots, the magnoliids, the basal eudicots, and core eudicots other than rosids and asterids. The monocots and magnoliids diverged prior to the eudicots from the angiosperm lineage. Our analyses include 78 samples from 10 orders and 14 families. The magnoliid exudates have diverse molecular origins. Within the monocots, the genus Aloe of the Xanthorrhoeaceae provides a conserved phenolic exudate that is different from the class called kinos and is proposed as a new class. Within the commelinid clade of the monocots, exudates of the Arecales (palms) are primarily gums, whereas those of the Poales (grasses) are diverse. A single sample from the Ranuncales within the basal eudicots is phenolic. The core eudicots (other than rosids and asterids) include the Saxifragles, from which the storax exudate of the genus Liquidambar of the Altingaceae is a terpenoid resin, not a phenolic material as previously reported. Also from the core eudicots, exudates from the Cactaceae of the Caryophyllales primarily are gums.
