The purpose of this study is to understand stem stele and vascular bundle types of monocotyledons. In order to attain the purpose, from total 749 classes of 26 families of Korean monocotyledons, 26 classes of 19 families were made into temporary sampling and paraffin method for observation. Stele types were classified based on shape of stem, availability of anomalous cambium, availability and position of aerenchyma, availability and position of bundle sheath fiber surrounding stem in a ring shape and arrangement shape of vascular bundle. Total 15 different types were observed namely, Zea, Lilium, Cymbidium, Dendrobium, Setaria, Allium, Canna, Cyperus, Narcissus, Commelina, Potamogeton, Acorus, Hydrilla, Luzula and Yucca. Zea type was observed in 1 class of 1 family, Lilium type was observed in 3 classes of 2 families, Cymbidium type was observed in 1 class of 1 family, Dendrobium type was observed in 1 class of 1 family, Setaria type was observed in 1 class of 1 family, Allium type was observed in 3 classes of 3 families, Canna type was observed in 2 classes of 2 families, Cyperus type was observed in 3 classes of 1 family, Narcissus type was observed in 1 class of 1 family, Commelina type was observed in 2 classes of 2 families, Potamogeton type was observed in 3 classes of 3 families, Acorus type was observed in 1 class of 1 family, Hydrilla type was observed in 1 class of 1 family, Luzula type was observed in 1 class of 1 family and Yucca type was observed in 2 classes of 1 family. Vascular bundles such as collateral vascular bundle, amphivasal vascular bundle and amphicribral vascular bundle were observed. Collateral vascular bundle was observed in 20 classes of 15 families, amphivasal vascular bundle was observed in 6 classes of 4 families, amphicribral vascular bundle was observed in 1 class of 1 family, and vascular bundle, consisting of only sieve tube was observed in 2 class of 2 family.
