Summary A number of recent publications have erroneously stated that the Orchidaceae are characterized by stornata that lack subsidiary cells. The situation is clarified in this article by information obtained from the study of development of the stomatal complex in Ludisia discolor and Spiranthes sp., representatives of the subfamily Neottioideae of the Orchidaceae, as well as by studies of mature stomata of five additional genera of the Neottioideae. These developmental studies document the presence of mesoperigenous subsidiary cells in the Neottioideae and also substantiate the presence of mesoperigenous subsidiary cells in at least one group of the monocotyledons.
