Abnormal stomata in monocots

Figure 1. The stomata of all species were anomocytic type and Epidermal
cell walls were straight in N. pseudonarcissus, I. langport, C. sativus, I.
tataricum and A. cepa, Only in A. reticulate was cross shape.

The present investigation describes abnormal stomata and cytoplasmic connections between guard cells of neighboring stomata in mature leafs of six species of the monocots. The study is made on leaves of Amaryllis reticulate L. Her., Narcissus pseudonarcissus L., Iris langport Wern., Crocus sativus L., Ixiolirion tataricum (Pall.) and Allium cepa L.

N. pseudonarcissus(2,5,6,7).

Anomocytic stomata type was observed in all species. Several stomata abnormally include single guard cells, aborted guard cells, arrested developments and cytoplasmic connection between guard cells of neighboring stomata was common to all species except in Allium cepa wasn’t observed cytoplasmic connection.
