0 a type of plant that produces flowers and has only one cotyledon (= leaf part inside the seed). Monocotyledons include daffodils and grasses. -- 單子葉植物（一種開花植物，種子內部只有一片子葉，如水仙、草等）
Her scientific research focused on the monocotyledon group of flowering plants.
Coverage of monocotyledon families is complete; other families are being added.
The leaves of the vast majority of monocotyledons lack petioles.
As the rainy season arrived, both the species took to a diet of mainly monocotyledons, and the impala consumed more of them.
All are monocotyledons, typically with narrow leaves and parallel veins.
The cotyledons contain (or in the case of gymnosperms and monocotyledons, have access to) the stored food reserves of the seed.
The plant bedding consisted of sedge and other monocotyledons topped with aromatic leaves containing insecticidal and larvicidal chemicals.
In the absence of secondary growth (most monocotyledons and a few eudicots), the endodermis commonly undergoes certain wall modifications.
