Lilioids - petaloid monocots

4 main groups: Diversity and • Acorales - sister to all monocots • Alismatids of Monocots – inc. Aroids - jack in the pulpit • Lilioids (lilies, orchids, yams) – grade, non-monophyletic . . . petaloid monocots . . . – petaloid • – palms – – spiderwort – – grasses & sedges
