The commelinids constitute a well-supported clade within the monocots, [5] and this clade has been recognized in all four APG classification systems. It consists of four orders: Arecales (palms) Commelinales (spiderwort, water hyacinth) Poales (grasses, rushes, bromeliads)
Asparagales (asparagoid lilies) are a diverse order of flowering plants in the monocots.Under the APG IV system of flowering plant classification, Asparagales are the largest order of monocots with 14 families, [5] 1,122 genera, and about 36,000 species, with members as varied as asparagus, orchids, yuccas, irises, onions, garlic, leeks, and other Alliums, daffodils, snowdrops, amaryllis ...
